During major renovations or construction, everything must be taken into account - even the width and height of the doors. The dimensions of the doorways, of course, can be arbitrary, but then you will always be forced to make doors to order. It’s easier to comply with standards - less costs and problems. Standard sizes of interior doors are specified in GOST. It may be old, but most of it is built according to them.

Standard door opening sizes

On the territory of the Russian Federation, there is also a standard from the times of the USSR, which describes the requirements and sizes of doorways and interior doors. There are quite a few technical specifications and DSTUs, but they have little relation to standards - each manufacturer writes them for himself. You can buy doors made according to technical specifications if their quality is high. But doorways should be made exactly of standard dimensions.

Why is it better to make them according to the standard? Because then there will be no problems with replacement. Almost all manufacturers make doors taking into account GOST. After all, high-rise buildings are built taking into account all the requirements (or should be built this way). If the opening has special dimensions, you will only have to order the doors. And this is a big expense, and there is no guarantee that you will like the finished product.

Dimensions according to GOST

So, even during a major renovation or construction of your own home, or when constructing interior partitions in a new building, in any case, we install standard doorways. GOST provides the following parameters:

• Width:
  • Single leaf 700 - 900 mm (in increments of 100 mm) and 1200 mm. It is recommended to install single-leaf doors in such doorways.
  • For double-leaf doors (the standard uses the term double-leaf doors), openings with a width of 1300 mm, 1500 mm and 1900 mm are made.
• The standard height of the doorway can be only in two options: 2100 mm and 2300 mm. The minimum permissible height is 2071 mm and 2271 mm, respectively.

These are the dimensions of standard doorways. No others. As for permissible deviations, the doorway can be 20-25 mm narrower than the standard one. In this case, it will also be possible to install a standard door block. Only the installation gap will be smaller, which will not make the work easier. That is, the narrowest doorway can be 675 mm (instead of 700 mm). Using the same principle, you can calculate the permissible deviation relative to each standard width. It can be reduced slightly, but not more than 25 mm.

What to do if the actual dimensions do not meet the standard

What to do if a few millimeters are not enough to meet the standard? Depends on the material of the walls, as well as on the actual width of the passage. If the walls can be machined, a few missing millimeters can be removed. Hew, grind, chop down. An axe, a chisel, a chisel, a grinder with a disc for concrete/brick, etc. Usually a couple of protrusions or curvature in some area interferes. If you level it, you can get closer to the desired size.

If the walls are made of very durable material, the only option left to adjust the opening to the standard is to reduce it to the next standard value. There are two ways: lay it with bricks, pieces of building blocks, or plaster. The second option is to install a foundation beam (treated with an antiseptic and dried), which, again, is covered with plaster, aligned with the walls. In general, you get the idea: it is more practical to bring non-standard dimensions to the standard.

Convenient sizes of interior doors

It is easier to determine the height of doorways. Everything here is tied up at the height of the ceiling. And the choice is small - only two options - 2.1 m and 2.3 m. But what about the width? There are more opportunities here. In general, there are certain recommendations that relate to the minimum door sizes. Namely doors, and not openings under them. The opening should be 70-100 mm wider. So, the dimensions of interior doors must be no less than the specified width:

• In technical rooms (storage rooms, bathrooms, baths and toilets) the recommended width of the canvas is 600 mm.
• For kitchens the minimum is 700 mm.
• For living rooms, at least 800 mm is recommended.

Of course, you can increase the size of interior doors if the doorway allows. Reduce at your own discretion. But the narrowest door leaf that can be found on sale is 550 cm, and even then it is inconvenient for obese people. In the kitchen and room where gas equipment may be located, the width of doorways is dictated and controlled by the fire safety service. So it won't be possible to do it anymore. Wider is possible.

As for residential premises, openings can also be made for double doors. That is, up to the maximum permitted in GOST 1.5 meters. There may be wider ones, but this is no longer standard. In a wide opening you can install not only conventional swing models, but also or. But large and wide doors look good in large areas. So the recommended sizes of interior doors were chosen for a reason. They took into account the not too large rooms in our homes.

How to determine what width the door leaf should be installed

If the doors are simply being replaced, the easiest way is to measure the door that is already in place. You definitely can't go wrong. If you are installing doors for the first time, you need to measure the doorway and select an option that will require minimal effort during installation.

How to measure a doorway

To choose the correct size of a door or door block, you need to know the exact dimensions of the opening in which they will be installed. Measurements are carried out using a regular construction tape. We measure any parameter at least at two points. If the difference is visually visible, you can measure more times, adjusting the position of the tape measure at your discretion.

The height of the doorway is measured at one and the other jamb, the width at the top and bottom, approximately at a distance of 30-50 cm from the floor and lintel. You can also take measurements in the middle of the height. You also need to measure the thickness of the opening (wall thickness). It must be checked at least at two points on each side.

We record all measurements. It is better to do this on a diagram of the doorway. If there are deviations, we look at how serious the situation is and whether it can be corrected. If the “narrowest” place corresponds to the smallest possible standard opening, you can leave everything as is. Otherwise, you will have to try to correct the situation. It is already described above how.

But size isn't everything. It is necessary to check whether there are any deviations in geometry. The side walls of doorways should be vertical, and the lintel should be horizontal. You can check the correctness of the shape using a regular building level (bubble level), but it is more convenient and accurate using. You can check the side walls with a regular plumb line. If the deviations are large, they need to be corrected. If their size is within a centimeter, it will be possible to compensate during installation using mounting plates and construction foam.

We select the sizes of interior doors and blocks

As already mentioned, the dimensions of interior doors are determined based on the dimensions of the existing opening. Doors are sold as a block assembled with a frame or just one leaf. It is more convenient to take the block - this speeds up installation. But it will be cheaper to buy the canvas separately and assemble the box. Here you choose either to pay less, but spend time and put in extra effort, or save time, but spend more money.

If you decide to buy a door block, make sure that its width (according to the outer dimensions of the door frame) is slightly less than the width of the opening. The minimum installation gap is 10-15 mm, optimal is 25-35 mm.

When purchasing only a door leaf, it is assumed that it should be 80-100 mm narrower than the opening. You will also need to add two jambs, and this is at least twice 25 mm each, plus an installation gap of 10-15 mm, plus a gap on the sides of the door leaf - 5 mm. Total we get: 25*2 + 15 + 5 = 70 mm. This is the minimum value that must be added to the width of the door. The resulting figure should be equal to or less than the width of the doorway in which it will be installed.

Entrance door sizes

The dimensions of entrance door openings are also standardized. They are described in GOST 6629-88. If you want to install standard products, make openings according to the recommendations. If you are building your own house, it is better not to install entrance doors smaller than the minimum width. And it’s not just the difficulty of finding suitable canvas dimensions. The fact is that there is a very high probability that the fire or gas department will force you to redo it.

Companies have their own standards for technical specifications

So, standard sizes of entrance doors can be:

• web width
  • for single doors - 900 mm, 1100 mm;
  • for double doors - 1400 mm (700 mm + 700 mm); 1800 mm (900 mm +900 mm).
• canvas height - 2300 mm.

If we talk about what is available for sale, then there are any doors. Moreover, you can order iron or wooden ones of any thickness. But again, this is non-standard. Although, the entrance ones are changed much less often than the interior ones.

A few words about what the doorway for the entrance doors should be like. According to the same standard, it should be 70 mm wider than the door leaf for single-leaf doors and 72 mm wider for double-leaf doors. These are the minimum values. A wider opening is possible, but a smaller one is not. The height of the doorway for installing the entrance door should be 71 mm larger. That is, for an entrance door with a leaf 900 mm wide, you need an opening of at least 970 * 2371 mm. Same with the others.

Replacing doors during the process is a very responsible matter. It is important not just to choose, it must fit into the opening. Adjusting the dimensions is often impossible without disturbing the structure of the coating. Taking risks in this case is very expensive. Therefore, when choosing, you need to take into account not only the design, but also the standard sizes of interior doors, standard markings, opening methods, and prepare as much as possible before going to the shopping center.

The purpose of interior products differs from those that are intended to protect housing from intrusion by strangers. First of all, they must be highly functional and provide comfort in the premises. The requirements for different rooms differ, but the main criteria can still be identified:

• Protecting the premises from unwanted visits. For example, it is necessary to create confidence that no one will accidentally interfere during procedures. In addition, protection is needed from increased noise, light, odors from the kitchen or drafts;
• division of space– this is necessary to delimit the premises into separate zones and organize the area according to its purpose;
• – the canvases must correspond to the general design of the premises.

Structures can be glazed or sheathed tightly. According to the opening method - cassette. The main selection criterion is that the canvas must completely cover the entrance.

Dimensions of interior doors according to GOST

The state standard has approved the dimensions of interior structures. In this case, it is necessary to take into account several parameters simultaneously: the length, width and thickness of doorways. All manufacturers adhere to certain standards. If necessary, structures can be manufactured according to individual measurements, but this will not be cheap for the customer.

Here are the main standard dimensions of interior doors with a frame for a leaf thickness of 44 mm:

You should know this! Standard parameters allow you to select and install the design as accurately as possible. However, its functionality will not be impaired.

How to correctly measure an opening

If it is not possible to invite a measurer, you need to measure all the dimensions yourself. To do this you will need a tape measure, a pencil and a piece of paper.

• Width measurements must be taken at the top and bottom at a distance of 20 centimeters from the top and bottom borders and in the middle;
• height is measured in two places: from the floor surface to the upper border. If there is a threshold, it should be taken into account when taking measurements;
• measuring the thickness of the door frame of an interior door. Moreover, if it is more than 100 mm, it will be necessary to additionally install additional elements in the form of slopes.

The gap between the box and the wall should be 15 mm. After installing the structure, it is filled with foam.

If you plan to install non-standard structures, for example, in the form of an arch, you need to contact professionals. It is quite difficult to perform such measurements correctly. You can draw a design on paper and give it to manufacturers.

Calculation of the proportionality of the box to the opening

If you don’t have a proportionality table at hand, you can calculate the necessary parameters yourself. To do this, you need to add the width of the box and the thickness of the installation gap on both sides to the width of the canvas.

• The standard width of the door frame is 25 mm;
• The recommended gap on each side is 15 mm.

Let's calculate the parameters of the opening width for a sash with a width of 550 mm:

550 + 25×2 + 15×2 = 630 mm.

To calculate the size of the opening for interior doors in height, you need to take into account:

• distance from the floor surface to the sash 10 mm;
• box thickness 25 mm;
• gap 15 mm.

The height parameters without threshold will be calculated as follows:

2000 + 25 + 15 + 1 = 2031 mm.

To install a box with a threshold, you need to add the height of the threshold instead of the indentation to the floor surface, and take into account the method of its fastening: with foam or screws.

Construction dimensions do not always fit into these formulas. In case of discrepancies, you can use the following tips:

• if a few millimeters of the opening width is missing, you need to expand it a little manually;
• if the frame is much narrower than recommended by building codes, you should select the appropriate dimensions for the extensions for the interior doors, they will close the free partition;
• if the product is installed in a load-bearing wall, its thickness may exceed the thickness of the box. For such a case, slopes are installed.

If none of the proposed options is suitable, the unit should be made to order.

Corridor Product Parameter Definitions

When choosing a product for a room, you need to take into account the dimensions of the openings. They must differ from the parameters of the valves. You cannot rely on standards; you must take your own measurements.

The standard height of doorways in the corridor is 2.01÷2.05 m. The width can vary within 1.28÷1.6 m.

In order to select a product according to these parameters, you can choose a double-leaf design with identical leaves of 60 cm, or different widths 0.6 + 0.8 or 0.6 + 0.9 m. The total width allows them to be installed in opening 1 .6 m.

Product marking

There is product marking in accordance with GOST; in practice, manufacturers make their own adjustments and designations. Let's first consider generally accepted norms.

The height and width of the structure are indicated in decimeters.

You can find individual manufacturer markings with other designations for the sizes of interior double doors, indicating the material of manufacture and the name of the product. Dimensions can be indicated in centimeters.

Standard sizes of swing interior doors with frames

Swing structures are installed in wide openings. Most often - in the living room. They attract attention and become the central element and decoration of the room. It is important to correctly determine the dimensions of interior doors with frames, as errors will immediately be evident.

Canvas dimensions

In apartments built in the last century, swing doors with a leaf width of 65 cm and a structure height of 230 cm were most often used. Currently, manufacturers have expanded the production of models and offer door frames with the following parameters.

Door frame dimensions

Swing door frames are made in a U-shaped design without thresholds. This is enough to completely fix the product around the perimeter. As in conventional models, when calculating the parameters it is necessary to leave a gap between the box and the opening.

Different materials are used in the manufacture of door frames. The width can be in the range of 15-40 mm; the optimal size is considered to be 30-35 mm wide.

Door opening dimensions

Manufacturers often indicate standard door opening sizes along with the product labeling.

The width can be determined using the formula:

width of two sashes + double frame width + double gap

The frame width is usually 30 mm, for the gap width you should leave 15 mm on each side.

To determine the height without threshold, you should include in the calculations the distance from the floor surface to the canvas of about 5÷20 mm:

sash height + frame width + gap + height from the floor surface

When installing a threshold, calculating the height is similar to determining the width.

Blade thickness

This is the third characteristic of interior structures. The strength of the entire structure and sound insulation depend on it. The standard thickness of the sheets is 40 mm. Manufacturers also offer thinner blades 20, 30, 36, 38 mm.

Products with a parameter of 50 mm can be produced upon individual order.

Interior doors of non-standard sizes

Free layouts of apartments and the construction of private houses require a non-standard approach to the design of premises. Often designs from . For such planning, standard parameters of door products may not be suitable.

By individual order it is possible to produce not only canvases of non-standard parameters, but also of an unusual design. In this case, it is important to take into account the thickness of the material, since drywall is limited in the perceived loads.

If you plan to produce a canvas of non-standard size, it is important to take into account some features and limitations.

• Reducing the height of the product is not recommended. Structures of increased height can be installed in rooms with high ceilings;
• when changing the width, it is important to consider the uniformity of load distribution. If the opening is more than 2 meters, additional supporting elements should be installed in the middle of the structure.

As a non-standard technique, you can change the width of one sash to a third or half of the standard width. This model is usually called one-and-a-half.

This is important to know! Manufacturing custom-made structures will increase the cost by 30÷40%.

Standard sizes of interior doors: main types and range

The modern market is filled with a variety of products. You can choose quite budget models or elite exclusive samples in different colors and designs. When choosing, you should take into account the basic design of the room.

Basic materials for making products:

Photo	Material
	Glass
	Tree
	, or MDF
	PVC

Classification of models by opening method

Manufacturers offer samples with a hidden box. To install such structures, certain requirements must be met:

• the thickness of the walls should not exceed 80 mm;
• the opening parameters must comply with the manufacturer’s recommendations, the vertical deviation is no more than 1 millimeter.

You can choose designs with a non-standard opening method. They save space; in addition, their attractive appearance will be a bright accent in the design.

• Swing models with the classic opening method, they can be left- or right-handed, with the hinges mounted on the opposite side.

• Sliding– significantly save space. They have one or two canvases moving along the floor surface along special guides.

• Harmonic- several canvases are folded in the form of an accordion; wide openings are required for their installation.

• Rocking are made from 1÷2 canvases, the mechanism allows you to open the canvases both inside and outside the room.

Conclusion

Interior doors complete the interior design. High-quality installation depends primarily on correctly performed measurements and calculations. When choosing a product, you need to take into account many parameters: material, weight and dimensions of the structure. Manufacturers offer a wide range of models that will fit into both regular and non-standard openings. If desired, you can make an individual design of structures.

Features of sizing can be seen in the video.

There is probably little that can be changed in renovating the interior of an apartment or private house without causing global devastation and without spending significant effort or financial resources so that it has such a practical and aesthetic effect as if you change the interior doors.

After all, no matter how beautiful the wallpaper or flooring is, when leaving the room, the last thing that fixes our consciousness is the decor and quality of the panel (canvas) with its frame. Therefore, such a final touch largely influences our perception of the design and comfort of the room as a whole.

Marking of door products

With the marking, which is the passport of the product, not everything is so simple. On the one hand, there are certain GOST designation recommendations, and on the other, the abundance of manufacturers sometimes creates confusion in the general standards. It is not uncommon that doors manufactured using the same technologies and having visual identity can be named and labeled in different ways.

First, let's look at the state standard, which no one has canceled. Thus, the production of wooden internal doors for residential and public buildings is still valid GOST 6629-88, according to which it is indicated (in order of positions in the marking):

Product type: D- door assembly, P- door leaf.

Fabric type: G- deaf, ABOUT- glazed, TO- glazed swinging, U- reinforced with continuous filling.

Height of the door with frame, in dm.

Width of door with frame, in dm. Additional letter indices: L- left door, N- with floating, P- with a threshold.

State standard index.

For example: DG20-10L GOST 6629-88 or PO19-7LN GOST 6629-88.

Despite the fact that any self-respecting manufacturer of door products still adheres to state standards, along with official model designations, entrances and individual factory codes. For example, one of the Russian brands uses such identification, producing doors 40 mm thick and 2000 mm high:

Model name.

Type of canvas. DG- deaf, DOF- with milled glass, DOOF- with two milled glasses.

Opening width, cm.

Veneer color.

Opening direction.

For a version of such products, you can read on the packaging: "Stella" DG 60 Oak lion.

Ultimately, no matter how different any factory marking is from the Gost marking, what is more important to us is the appearance, structure and operational properties of the door, about which you will need to ask the seller in detail and carefully study the company passport attached to each product with its characteristics and installation instructions.

What do you have to deal with or what types of doors are there?

The market does not allow you to relax in search of a suitable model, offering a seemingly huge variety of door products. However, upon closer examination, several main types of products can be distinguished:

For painting

Allows you to achieve a complete color combination with the surrounding design. Supplied primed, completely ready to be coated with decorative interior compositions.

In this group of products, two subtypes should be distinguished - elite and budget oriented. The expensive segment of doors for painting is produced for the so-called hidden installation. After installing and tinting such a product, only a protruding handle can indicate the presence of a passage in the wall.

Budget models can be found in many public institutions; they are also widely used in “economy” apartment renovations and as temporary options. They are a textured MDF coating on a timber frame. Their main advantage is the lowest price among all door designs.

Laminated

They are delivered to the retail chain ready for installation. In many ways, the design is reminiscent of the previous budget class. However, they have a stain-resistant coating laminated with a polymer film that can imitate any decorative material.

They can be filled with heat and sound insulating materials: corrugated cardboard, mineral wool, polyurethane foam or polystyrene foam. There are models with smooth or textured surfaces, as well as with profiled overlays made of pressed MDF.

Veneered

They are the next, higher level in quality and appearance. The basis for them is the same frame MDF with different types of fillers. The thinnest sections (0.7 mm) of valuable wood - veneer - are glued onto the base, which are then varnished. The result is a complete imitation of a product made from massive material, but with less weight and an affordable price.

Made from solid wood

You probably shouldn’t once again praise products made from completely natural materials. In addition to all its advantages, such a door will add sophistication and comfort to any interior, if you are willing to pay its high cost. However, one should not forget that wood is very sensitive to changes in humidity, therefore, for the long service of such elite products, mandatory control of the indoor microclimate is required.

Glass

They also belong to the high price segment of the market offerings of door products. They help in the implementation of special design delights, and are also ideal for installation at the entrances to bathrooms, showers, saunas and other places with high humidity. They come in transparent, translucent, matte, colored glass and with surface milling.

Metal-plastic

They serve as a good solution for exits to loggias, terraces, as well as for damp rooms, as a cheap alternative to glass doors. They have excellent sound insulation and heat retention qualities. The surfaces of products can be laminated with films to match any natural material

About dimensions and more. Standard sizes of interior doors

If we do not take into account the non-standard approaches of some private customers, for whom the binding of door dimensions is based on subjective requests and desires, then most manufacturers are guided by standard openings of typical buildings from the Soviet period. And why reinvent the wheel - from the point of view of the ergonomics of door products designed for the physiology of the human body, everything has long been invented and thought out.

At the same time, the share of individual requests (regarding product sizes) on the market is small, and therefore is successfully filled by the efforts of small private manufacturers, although they are much more expensive than standard models.

The ratio of the sizes of doorways and doors (door frame + leaf) according to domestic SNiP. From the tables below you can find out the size of the doorway for a door with a width of, for example, 80 cm.

The ratio defined by the DIN standard:

Width

First of all, when talking about the size of doors, both swing and sliding, any of us means the width of the door that we will use every day. In some places you need and want a wider one, but in others a narrow alignment is enough. Gostov's proven recommendations offer the following parameters:

For bathrooms - 600 mm,

For kitchens - 700 mm,

For living rooms - 800 mm.

If we consider real market products, then their range (adjusted to the needs of modern consumers) is somewhat wider:

For bathrooms - 550 mm And 600 mm,

For kitchens - 700 mm,

For living rooms - 800 mm And 900 mm.

Let’s not undeservedly forget double doors, because they often emphasize the special status of living rooms or passages to terraces. They are usually made up of the same standard fabrics in equal and unequal combinations, for example: 600+600=1200 mm or 600+800=1400 mm. Also for the “kopeck piece”, narrowed segments are used 400 mm - 400+400=800 mm or 400+800=1200 mm.

Height standards

If we start from the domestic “classics”, then they have been preserved in the proposals 1900 mm And 2000 mm, although now the European standard is also often found - 2100 mm. Higher products can also be installed - 2300 mm and even to the ceiling. It is clear that such “giants” are more convenient to use in a sliding version.

The thicker the canvas, the better?

Is it always like this? What does this parameter affect? Of course, massive thick doors perfectly highlight the interiors of living rooms, especially those made in the Empire, Baroque, and Renaissance styles, but thin screens and sliding partitions will be an excellent addition to passages to pantries or dressing rooms.

The thicker the door, the heavier it is (in its group of design solutions and type of materials), therefore, the requirements for its hinged fittings will be higher; it may be necessary to install additional hinges, which in total will lead to an increase in the cost of the entire product. Therefore, the choice of canvas based on the criterion of massiveness, as well as on other parameters, should be based on rationality and optimality.

Typical products prevailing on the market have thicknesses in a range of sizes 30-40 mm. Already in this fork of parameters, you can most often find doors 35 mm And 40 mm, as well as with intermediate values 36 mm And 38 mm.

In addition to the indicated running dimensions, sliding MDF partition doors can be very thin - from 20 mm, but products from solid wood enterprises are unlikely to be produced with a base cross-section less than 40 mm(can reach up to 50 or more on special orders). It should be noted that doors made of tempered glass, whose thickness starts from 8 mm, have come to private interiors relatively recently, but are gaining popularity.

What else is good to know when choosing an interior door?

When taking measurements of the opening to purchase a new door, keep in mind that it should be at least 30 mm larger dimensions of the box along the top edge and width. The installation gap will be required to adjust the product using wedges, followed by fixation with polyurethane foam. Of course, this value is relevant for the opening that is correct in relation to the vertical and horizontal.

Most boxes are made thick 35 mm. Those. dimensions of the width of the product assembled with the canvas 800 mm will 870 mm (+35 mm*2). Similarly, the size increases in height, although you still need to take into account whether there is or is not a threshold.

Thick doors retain heat better and counteract noise from adjacent rooms.

When installing the box, before installing the floor coverings, carefully calculate the level of the finishing surface. If the door starts to rest on the floor, then it is very difficult to trim it perfectly on your own, and this cannot be done with every model.

In conclusion, we can say that the interior door structure, despite the apparent simplicity of the device, is quite sensitive to installation errors. Therefore, either its installation and configuration will take a lot of your time, or you will have to involve highly specialized specialists.

Interior doors are designed to separate two interior spaces. Depending on what rooms they delimit, the parameters of the openings, the door material, opening methods, the presence of decorative elements and the geometric parameters of the door are distinguished. The standard box size may vary in each case.

Door block dimensions

Domestic door blocks can be 60-90 cm wide (depending on whether single-leaf or double-leaf doors) and 1.9-2 m high. Such standards, taking into account the frame, were already established by Soviet GOSTs for standard buildings.

European parameters of a single-leaf door: height - up to 2.3 m: width 60-90 cm (in the bathroom - 55 cm). For a double-leaf door - the width is 1-1.8 m. Moreover, if the door has the same leaves, the width of the leaves will be 0.7 m, with different dimensions - 0.6 and 0.8 m.

The frame can come as a kit or be a set of beams that must be assembled immediately before installing the door. It can be 1.5-4.5 cm in thickness, which means the width of the opening should be twice the width of the canvas. The same rule applies to height, taking into account the presence or absence of a threshold.

Standard sizes of interior doors with frames according to Euro standards are often indicated in modules (one module is equal to 10 cm). If the marking says M21, the door height is 2.1 m. What options can be found on the modern market are shown in the table in the photo.

If you take measurements yourself, you must take into account the requirements of SNiPs: the door must open in such a way as not to block access to other rooms or passages. In addition, you need to think in advance about what material the door will be made of (plastic, MDF, wood). In some cases, it is more expedient to widen the opening itself and order doors to non-standard sizes with a different opening radius, for example, if the door covers furniture or the entrance to a nearby room. Here it is more profitable to install a telescopic door.

How to determine the right size

Using a plumb line or level, determine the verticality of the slopes, measuring them on both sides, and drawing a horizontal line, find the width. The height is measured from the highest point on the floor to a horizontal line drawn from the corner of the opening.

The depth of the opening is measured along both walls and from above. On all slopes, measurements are taken at the top, bottom and middle. If the old door is not removed, determine the thickness of the frame and the parameters of its protrusion beyond the wall.

Standard and custom sizes

Regulated heights of interior fabric: 190-200 cm. They are used for openings of 194-203 cm and 204-211 cm. A 190 cm door is made with a width of 55 or 60 cm. For leaves of 20 cm - 60, 70, 80, 90 cm and double doors, width - 120, 140, 150 cm. The width of one door is 60 cm, the second can be as follows same or 80, 90 cm. Conventional dimensions in the table Further.

Which doors to choose are standardized by GOST. The living room needs a double door. The width of one leaf is 60 cm or 40 and 80 cm, which gives a total of 1.2 m. Height is 2 m with an opening depth of 7-20 cm.

A door with dimensions of 80x200 cm can be installed in a living room, with the same opening depth. For the kitchen: 70x200 cm, and for the bathroom - 55x190 cm or 60x200 cm, wall thickness - 5-7 cm.

If you need a door of non-standard sizes, you will have to make a custom order. In terms of price, it will be 25-40% more expensive. An increase in cost can also be expected with extraordinary design solutions (stained glass, forging, bas-reliefs).

Before purchasing a door, it is simply necessary to measure the dimensions of the opening. The fact is that GOSTs of past times adopted a standard height of 2 m. But modern manufacturers are guided by new parameters of 2.1, 2.2 and 2.3 m. However, not all new buildings are built according to these standards. It is important to remember that if the door is larger than the opening, the situation can be corrected, but if it is smaller, nothing can be done.

If the home has high ceilings, interior doors should also be higher than standard sizes. Here the costs of an individual order cannot be avoided. Therefore, the dimensions of future canvases with a box and the mechanism for opening them must be calculated at the stage of rough repair work. It is up to the owners to choose which model to install based on the ease of opening.

To determine the height of the opening, you need to decide whether the doors will be installed without a threshold elevation or with it.

As an example, let’s take the following parameters: height – 2 m, width – 0.8 m, box thickness – 0.03 m.

Calculation of the opening width: 0.8 + 2x0.03 + 2x0.015 = 0.89 m. Here 0.015 m indicates the approximate size of the gap that is needed to align the box relative to the slopes.

In the absence of a threshold, the width calculations are as follows: 200+3+1.5+1=205.5 cm (2.055 m). In this case, 1 cm will be needed for the clearance left under the door. If there is a threshold, 1 cm is added to its height. Parameters required for the door: 0.89x2.055 m.

Door material

Plastic is the lightest - up to 5 kg. Such a door cannot cause serious injury when opened if there is another person behind it. It will not cause trouble in operation for people with disabilities or children. Suitable for common areas: bathrooms, kitchen, utility room, as well as for a nursery or bedroom.

A glass interior door can weigh up to 19-23 kg. It is usually installed at the entrance to the living room or to delimit the space in the kitchen into a work area and a dining room.

Wooden doors are the heaviest - 26-45 kg. Such models are suitable for offices and libraries. With stained glass inserts - for the living room or dining room.

When choosing what the door will be made of and what size it will be, you need to know the characteristics of the partition: what it is made of and whether it is load-bearing.

In order to know the standard sizes of interior doors with frames, you need to study generally accepted standards. In addition, there is a special table with exact indicators. It is necessary when ordering, purchasing, and then installing the door leaf indoors. Each manufacturer has its own methodology for creating doors, but they are required to adhere to regulations. Below are the GOST standards on the basis of which standard doors are produced, tables with dimensions and possible markings.

Door size standards

GOST parameters must be taken into account not only when creating a door or frame, but also when calculating the opening. GOST standards related to interior doors:

• Opening to the kitchen - GOST 702007;
• For toilets and bathrooms - GOST 55-60190-2005-7;
• Bedroom – GOST 802007-20;
• Living room - GOST 2007-20.

The latter refers to double doors and an opening that must comply with the standard. Most often, when installation is carried out without the participation of a specialist, the standards prescribed in these documents are not taken into account. The construction market offers a lot of modern models of door leaves, but most often their size indicators have standard numbers: 200 cm, width 60-80 centimeters. The thickness of the box varies from 15 mm to 45 mm, but if you make an individual order at the factory or it is home-made, the thickness may vary.

If you do not comply with GOST standards for door sizes, this may lead to the need to expand the opening.

Common parameters

GOST standards state that the parameters of the box must correspond to the dimensions of the canvas, taking into account the gaps required for installation of the structure. If the manufacturer created the model correctly, the indicators will be as follows:

The proportionality of the frame and the thickness of the wall opening must be observed. If you purchased a canvas of a smaller size, it doesn’t matter, you can use such a device as an extension. It will tightly close the gap and hide the miscalculation.

The standard size of a door frame, which is prescribed in regulations, for a door to a room in height should be 190-200 cm. If the doorway is two meters, then the door itself is ordered several centimeters smaller. If this is not taken into account, then it will not be able to open and close freely.

The standard thickness of the canvas is 4.5 cm. The width, as a rule, depends on the dimensions of the room itself.

Double doors have their own characteristics. Wide openings can be present at the entrance to any room, but they are most often found in living rooms. GOST reports that the width of these canvases should vary from 120 to 150 cm. These parameters contain functionality and ease of use.

The largest sizes of door frames used by manufacturers in Russia for interior doors are 90 cm wide. As a rule, they are installed in industrial production, in offices or in large country houses. The opening should be proportional to the room itself. If the room is small, then a massive door leaf will look awkward or cumbersome. It is worth noting that in Soviet “Stalin” buildings this parameter was used, since the living area is very spacious. Such doors are produced in small quantities, and not very large enterprises make them exclusively to order.

Marking

The dimensions of the door directly depend on the dimensions of the opening. The markings even for absolutely identical doors may vary, but all wooden door structures must comply with GOST 6629-88. It states that these parameters are used for the manufacture of interior doors for residential and public buildings. The type of product is marked with the letter “P”, which means panel, and the letter “D” indicates that the product is prefabricated. There is a difference in the type of cloth. If the abbreviation is “O”, it means the product is glazed, and if the letter is “U”, then the glass is made with continuous filling.

You can also find markings in the form of the letter “P”, which means that the product has a threshold, or “L”, telling the buyer that the door is left-handed.

Canvas and box sizes

According to SNiP, the standard size of an interior door with a frame is divided into several separate indicators, which are reflected in the table:

If we talk about the European standard, the ratio will be as follows:

The Russian width of the canvas for the kitchen will be 70 cm, for the toilet or bath – 60 cm, and for the room – 90 cm.

Measurement formulas

To take measurements yourself, it is not necessary to call a specialist for this. First you need to take into account such nuances as:

• Height;
• Width;
• Thickness;
• Platband parameters.

If the height of the canvas is 200 cm, the width is 70 cm, the frame is 3 cm thick, then the gap should be 1 cm, the door block should be 2 cm, and the height of the threshold should be 2 cm. To make calculations, these numbers must be substituted into the following formula: W dv +2*T k+Mz+2*Bd. The result will be: 70+2*3+1+2*2=81cm. If you need to find the height of a doorway with the same parameters, then the formula is as follows: B dv + B p + 2 * T, it turns out: 200 + 2 + 2 * 3 = 208. As a result, it turns out that a door with parameters of 200 by 70 requires a doorway measuring 208 by 81.

The standard opening depth is 7.5 cm, so manufacturers create door frames for this size. If the door has already been purchased, but it turns out to be smaller than required, you can find a way out of the situation - buy additional elements.

Algorithm for measuring the size of a doorway

The measurement process itself is no less important. Experts assure that it is precisely in this work that mistakes are most often made, and, accordingly, subsequent calculations will be incorrect. To ensure that the door frame in a residential or public space for interior doors is measured correctly, and the dimensions allow for correct calculations, the following sequence of actions must be followed:

• First, the height changes from the floor itself to the top of the opening. If you are sure that it is not level, measurements should be taken in the middle;
• The width is measured from the middle of the left to the middle of the right casing;
• The depth can only be known by taking comprehensive measurements: at the top, middle and bottom to find the widest value.

Standard table for calculating doorways:

If a person lives in an apartment or house with a standard layout, then the indicators of his measurements will be identical to those indicated in the table.

Box and gaps

When purchasing a door leaf, you need to pay attention to the dimensions of the interior doors, which are indicated on the packaging. There should be an explanation that the dimensions are written along with the box. As a rule, they should be increased by 10-15 cm when compared with the door dimensions. We must not forget that a gap should be left between the wall and the mounting panel, so the parameters of the panel should be less than the characteristics of the frame. Experts also recommend purchasing the structure along with cashing, frame and fittings.

To make the box, manufacturers use bars, which can also vary in size. Average width: 1.5-4.0 cm, but the standard indicator: 3.0-3.5 cm. Only with the latest indicators can you count on the structure being strong enough and will last for many years. It is important to pay attention to the thickness of the box. It is best that it matches the parameters of the wall. For brick buildings it is 7.5 cm, and for wood it is 10 cm.

Conclusion

When it comes to standard premises, the applicant should not have any difficulties in choosing a door design and installing it. This applies more to apartments. When a person builds a house on his own according to an individual design, then the doors will have to be made to order, after taking measurements. If a person is afraid of making mistakes in measurements, then it is better to entrust this work to specialists.
