In order not to stop work during the renovation of the bathroom due to a lack of material or not to think about where to put its excess, it is important to correctly calculate the need for tiles. There are several calculation methods, depending on the type of tile laying and differing from each other in accuracy.

With a monotonous finish of the bathroom, when the same type of tiling is used for facing all surfaces (straight, diagonal or offset), the need for tiles is calculated in square meters or by the piece.

The amount of ceramics necessary for the implementation of complex artistic cladding must be calculated separately for each independent fragment of the room decoration. Let's consider these methods.

Calculation of ceramic consumption in square meters

When choosing a monotonous type of tile laying, dimensions are measured: length, width, height - rooms in meters to the nearest hundredth (centimeter), rounding fractions of a centimeter up.

Calculation of the cost of finishing the floor

To calculate the quadrature of the floor, multiply the metric values ​​\u200b\u200bof the length and width of the floor, after which the result is rounded up to integer units. If laying is carried out in a direct way or "with an offset", 10% must be added to the amount obtained. If ceramics are laid diagonally, 15% is added to the floor area.

For example:

The area of ​​​​the room with a length of 4.21 meters and a width of 2.34 meters is:

• 4, 21 x 2, 34 = 9, 8514 sq. m. Rounded to the nearest 10 sq. meters.

Adding 10%:

• 10 x 1.1 = 11 sq.m.

With the diagonal method, you need to add 15%, it turns out: 10 x 1, 15 = 11.5 square meters. ≈ 12 sq.m.

Calculation of material for wall cladding

The square of the surface of the bathroom walls is calculated by multiplying the perimeter of the room and its height, the resulting value is also rounded up to integer units:

(4, 21 + 2, 34 + 4, 21 + 2, 34) x 2, 68 = 35, 108 sq. m. ≈ 36 sq. meters.

Then measure the height and width of the doorway in meters to the nearest centimeter, rounding fractions of a centimeter down. Multiplying these values, get the area of ​​the doorway, rounding it down to tenths of a square meter.

For example:

• the area of ​​a doorway measuring 2.1 x 0.8 is 1.68 sq. m. ≈ 1.6 sq.m.;
• from the surface area of ​​​​the walls subtract the area of ​​\u200b\u200bthe doorway 36-1.6 m \u003d 34.4 square meters.

10 or 15% is added to the result, depending on the type of tiling and rounded up to integer values:

• direct or offset method: 34.4 sq.m. x 1, 1 = 37.84 sq. m. ≈ 38 sq.m.
• diagonal way: 34.4 sq.m. x 1, 15 = 39, 56 sq. m. ≈ 40 sq.m.

If you do not clad the walls for bathroom, then the area of ​​\u200b\u200bthis hidden surface is also subtracted from the area of ​​\u200b\u200bthe walls, but this savings leads to a weakening of the waterproofing of this area behind the bathroom, which is fraught with damage to the finish in the adjacent room by seeping condensate.

Having calculated how many square meters of tiles are needed for repairs, they purchase finishing material. The packaging of ceramics indicates how many square meters of cladding it contains. To calculate the required number of packs correctly, the need for tiles in square meters must be divided by the quadrature indicated on the package and rounded up to integer values.

Calculation of the consumption of tiles per piece

Piece counting has a smaller error, but this advantage also has a downside - with this method there is no material left in case of accidental damage to the tile during installation or unforeseen spot repairs of the cladding.

With this method, measurements of the dimensions of the room are also made, but in centimeters, rounding fractions of a centimeter up to integer values. For example, a length of 420.5 cm is rounded to 421 cm, a width of 233.7 cm to 234 cm, and a height of 267.6 cm to 268 cm.

Then a certain tile is looked after in the distribution network and the dimensions of one tile are measured. For example, the tile chosen for the walls has a width of 15 cm, a length of 20 cm, and ceramics of 20 x 20 cm were chosen for the floor. To calculate how many pieces of tiles are needed for wall cladding, the consumption must be calculated for each wall separately.

Piece calculation of ceramics for walls

In our example, the bathroom has two walls with dimensions of 421 x 268 cm and 234 x 268 cm. If the tiles are laid vertically, then 268:20 = 13.4 pieces will fit from floor to ceiling. With a minimum width of tile joints, this value should be rounded up to 14 products.

In length, 421:15 = 28.06 pieces will fit on one wall, and 234:15 = 15.6 pieces on the second. Let's round up to 28 and 16 products.

We consider how many pieces will be needed for finishing:

• 14 x 28 = 392 pieces; multiply by two walls, we get 784 products.
• 14 x 16 = 224 pieces; we also multiply by two walls, we get 448 products.

On vertical surfaces, 1232 pieces will be required, but from this amount you need to subtract the number of tiles corresponding to the area of ​​​​the doorway. Suppose the doorway has dimensions of 210 x 80 cm. Its height will fit 210:20 \u003d 10.5 pieces. Round down to 10. The width of the opening will fit 80:15 = 5, 33 pcs. Identical round up to 5 products.

Therefore, the area of ​​the doorway corresponds to the area of ​​10x5=50 pieces. tiles to be subtracted from the total for walls: 1232–50 = 1182 pieces.

Piece calculation of ceramics on the floor

Let's calculate how many products of the 20x20 cm format will require floor cladding with dimensions of 421x234 cm:

• in length 421 cm: 20 cm = 21.05 ≈ 21 pieces;
• wide 234 cm: 20 cm = 11.7 ≈ 12 pcs.

Multiplying these values ​​​​gives the number of tiles per floor in pieces:

• 21 x 12 = 252 items.

Calculation of ceramic consumption for complex artistic finishing

If it is decided to make the decoration of the bathroom exclusive, the calculation of ceramics is done in a combined way - by the footage and by the piece. On horizontal and vertical surfaces to be decorated, it is necessary to make markings according to a previously developed cladding sketch map. By this time, as a rule, the necessary types of ceramics are already scheduled for purchase, and the format of the facing material with which the bathroom will be finished is known.

Marking is carried out with construction chalk, it starts from sections of the main plan, which will be occupied by artistic panels and ornaments, trimming of which is not allowed for aesthetic reasons. How many tiles are needed for facing such surfaces is easy to calculate piece by piece.

Then they calculate the consumption of tiles for the frieze (if available on the sketch map) and lining under the background for the panel. How much material is needed for laying the frieze can also be calculated by the piece method.

The choice of method for calculating the amount of ceramics when decorating the main background depends on the cost of the material, since not everyone plans to purchase excess expensive tiles.

Results

The accuracy of calculating the consumption of ceramics when finishing a bathroom depends on the pricing policy. If after the end of the work there is a meter or two of facing material left, do not rush to call it a calculation error. This surplus will be indispensable for unforeseen spot repairs of the cladding. It is much worse when there was not enough material, and this type is no longer on sale.

Getting to the finishing work in the bathroom, you first need to calculate and purchase the required amount of material. It is advisable to immediately buy the entire volume, since the next batch may differ in tone, so the calculations must be performed very accurately. In this case, tiles are used to finish the walls and floor. Manufacturers offer material of various shapes and sizes. Which collection will be preferred will largely depend on how many tiles per bathroom will be required. There are several calculation methods that we will introduce you to today.

Preparatory stage

Before proceeding with the calculation, you must carefully measure the bathroom with a tape measure or rangefinder. The following parameters are required for the calculation:

• Wall height.
• Wall width.

If the walls have the correct shape, it will be enough to make two or three measurements. If there are niches or various protruding elements, it will be necessary to measure their parameters too and clarify the dimensions of the door.

Even if at first glance the walls seem perfectly even: square or rectangular, be sure to take a few control measurements. This will avoid errors in the calculations.

Required number of floor tiles

First way

Calculations begin with determining the floor area. To do this, its length is multiplied by its width. Then, the area of ​​one tile is calculated in the same way. After that, the first value is divided by the second, and the result is rounded up. The result is an approximate value, which experts recommend increasing by 5% by multiplying by a correction factor of 1.05. The resulting value is again rounded up to a larger integer.

As an example, consider a bathroom that has a ceiling of 2.65 m, walls of 1.8 m and 1.7 m, and a door 0.6 m wide. In this case, if the floor tiles are 33 cm by 33 cm, you will need: ((1 .8 * 1.7) / (0.33 * 0.33)) \u003d 28.1 pieces; 29*1.05"31 tiles.

Second way

The calculation of the number of tiles for the bathroom begins with determining the number of tiles that will need to be laid in length and width. To do this, divide the length and width of the room, respectively, by the length and width of the tile. We multiply the obtained values ​​​​by each other, round up to a larger integer and also increase by 5%.

According to the above example, we obtain the following sequence of calculations:

1. 1.8/0.33=5.5 pieces;
2. 1.7/0.33=5.2 pieces;
3. 5.5*5.2=28.6 pieces;
4. we round the value obtained in paragraph 3 to 29;
5. 29*1.05=30.45 pieces, i.e. to finish the floor (after rounding up), you need to purchase 31 tiles.

If, when calculating one of the methods, a larger value is obtained, it is worth choosing it. However, it is worth noting that sales consultants prefer to use the first option.

Required number of wall tiles

First way

To determine how many bathroom tiles are needed for wall cladding, we calculate the perimeter of the room. To do this, we sum up the lengths of all its walls. If we are talking about a standard bathroom, it is enough to add the length and width and multiply by 2. In our example: (1.8 + 1.7) * 2 = 7 m.

Based on the perimeter, the required number of friezes is calculated. To do this, the width of the door is subtracted from the perimeter of the bathroom. The resulting value is divided by the length of the frieze or border, respectively.

If desired, you can save money if you do not clad the part of the wall located under the bathroom. In this case, it will be necessary to subtract the area pertaining to this area from the total calculations.

So, for example, assuming that the dark tiles will be laid at a height of 1 m, we get that the height of the light top will be equal to: 2.7 m -1 m - 0.08 m (frieze height) \u003d 1.62 m. Now you can calculate the required number of tiles. For this:

• We calculate the area that will be occupied by light and dark tiles.
• The resulting values ​​are divided by the area of ​​​​one tile.
• Round up to the next integer value.
• We increase by 5%.
• Round up to a whole number.

In our example, we need:

• Dark tiles: (7-0.6)*1/(0.2*0.4)=52.5pcsÞ53pcs*1.05=55.56Þ56pcs;
• Light tiles: (7-0.6)*1.62/(0.2*0.4)=55.05 pcsÞ56 pcs * 1.05=90.3Þ91 pcs.

If decorative inserts are planned, then the number of light or dark tiles should be reduced by the amount of decor purchased

Second way

In this case, we do the layout of each wall in order to understand how many tiles can be placed in horizontal and vertical rows. In this case, the tiles that need to be cut are taken into account as whole. We increase the resulting value by 5% to insure ourselves in case of marriage or battle. We calculate the required number of dark, light tiles and borders and go shopping.

Thus, knowing the above methods, everyone can calculate how many tiles per bathroom they need on their own. It is only necessary to take measurements correctly, decide on the type of tile, as well as how it will be located on the wall and floor.

Depending on the specific type, the cost of ceramic tiles can reach high values. Its rational use is one of the options for reducing the cost of finishing work. Correct calculations of needs are an effective way to save money. How to calculate bathroom tiles accurately and reduce waste? Work should be done in several stages.

First, consider the simplest option for finishing the walls of the bathroom - ordinary plain tiles are used for work.

We will not touch on the decorative side of the matter, let's talk about its characteristics from the point of view of tilers. They are very fond of this material for several reasons:

• during laying, there is no need to monitor the placement of individual tiles, taking into account the pattern. This not only greatly speeds up the laying process itself, but also simplifies the layout. You can start laying tiles from any angle and place; you do not need to select its position to obtain a symmetrical pattern;

  Such mistakes cannot be made when working with plain tiles.

• tiles can be cut from any side, segments are used without regard to the location of the pattern;
• it is possible to use pieces of tiles from one corner wall to another without prior adjustment. Less work and less waste.

We will describe the technology for calculating more complex tile options below, but now we will consider a simple option.

Important. Tiles are sold in packs, in a pack of 0.5 m 2, 1 m 2 or other quantity (check the number on the package). It is unlikely that any of the distributors will agree to sell tiles by the piece, in this regard, you should not count the number of pieces, operate with square meters. By the way, these calculations are universal and suitable for determining ceramic tiles of various sizes, and they can vary widely.

Step 1. Measure the length of all walls in the room. Use an ordinary tape measure, write down the data in a notebook or on a piece of paper. Sum the total length of the perimeter.

Step 2 Measure the height of the room, round the resulting values ​​​​to the nearest centimeter.

Consider an example. How to calculate the tiles in the bathroom on the walls? Start by tying in the length of the perimeter. Calculation: 1.5 m + 3.0 m + 1.5 m + 3.0 m = 9.0 m. For example, our ceiling is at a distance of 2.7 m from the floor. Total surface area 9.0 m×2.7 m = 24.3 m 2 .

Step 3 From this value, subtract the area of ​​the door and window opening.

Doorway dimensions 2.0 m (height) × 0.9 m (width) \u003d 1.8 m 2. If there is a desire, then add the area of ​​\u200b\u200bplatbands to the opening area. Their width can vary from five to ten centimeters. But we do not recommend doing this for several reasons.

1. The savings are not big enough to pay attention to. And any calculations may be in error, you should not risk it again.
2. Some types of platbands are fixed to surfaces with liquid nails. It is fast and beautiful, carnations or self-tapping screws are not visible. And liquid glue holds well with even surfaces; using it on ceramic tiles is the best technology.
3. Not all walls in the bathroom are even, some have to be corrected under the architraves. Why do the same job twice - put ceramic tiles around the perimeter of the opening, do not waste time in vain.

The same applies to the window opening, if there is one in the room, of course. In our example, there is no window, which means that the area of ​​\u200b\u200bthe walls is 24.3 m 2 - 1.8 m 2 = 22.5 m 2. But this is not yet the final figure.

Step 4 Measure the tub.

If it is installed against a wall, then there is no need to tile invisible surfaces. For example, the width of the bath is 0.7 m, the length is 1.7 m, the height is 0.6 m. The bath will adjoin two walls, one end, and the second side. You need to calculate the area of ​​contact. From the end, it is equal to 0.6 m (height) × 0.7 m (width) \u003d 0.42 m 2. From the side, it is 0.6 m (height) × 1.7 m (length) = 1.02 m 2. We add these values ​​\u200b\u200b0.42 m 2 + 1.02 m 2 \u003d 1.44 m 2.

Step 5 We calculate the exact surface area of ​​\u200b\u200bthe walls of the bathtub for tiles: 22.5 m 2 (without a doorway) - 1.44 m 2 (adjacent area) \u003d 21.06 m 2, after rounding we get 21 m 2.

Important. If the decorative screen will be finished with the same tiles, then its dimensions are not deducted.

As with any construction work, unproductive tile waste is indispensable. What stock to keep? Several factors need to be taken into account:

• qualification of a master tiler. If a professional works, then 5% is enough. For a beginner, the total number of tiles should be increased by 10%;
• decorative characteristics of tiles. If there are asymmetrical patterns on the tile, then the segments cannot be used. The stock must be increased to 10%, regardless of the skill of the performer;
• availability and location of water and sewer pipes. During the finishing of these obstacles, the tile consumption may increase.

Tiles can be laid in a standard way (rows parallel to the floor), in a checkerboard pattern, an ordinary diagonal pattern, and a diagonal checkerboard pattern. Keep in mind that during the checkerboard-diagonal method, the amount of waste may increase slightly, but a margin of 10% in any case will be enough. This completes the count, you can go to the store for the material.

wall tiles in the bathroom

What to do if there is a curb in the bathroom

Step 1. Measure the height of the border and the number of rows of tiles. The height must match the dimensions of the tile.

Step 2 Measure the length of the walls along which the curb will be laid, multiply the value by the height. You will get the total area of ​​\u200b\u200bthe curbs.

Step 3 Calculate the area of ​​one tile, divide the area of ​​the borders by the area of ​​the tile. This quantity must be increased by 3-4 pieces. depending on the number of turns.

Calculation example:

• the length of the walls minus the doorway is 9 m (perimeter of the bathroom) - 0.9 m (width of the doorway) = 8.1 m;
• curb area for tiles 15 cm high: 8.1 m × 0.15 m = 1.215 m 2;
• the border has a height of one tile 15 cm. The area of ​​the tile is 0.15 m × 0.15 m = 0.0225 m 2;
• number of tiles. 1.215 m 2: 0.0225 m 2 \u003d 54 pcs. 2 pieces are enough for stock, total buy 56 pieces.

If a decorative pattern is planned on the wall, then it is purchased separately. The size of the picture is indicated on the package. Accordingly, this value must be subtracted from the total surface area, only the missing tile should be purchased.

Calculation of plastic corners

The use of such corners speeds up the process of laying tiles, allows you to hide small errors made during the measurement or cutting of tiles. They are installed in internal and external corners, at the junction of the wall and floor. They have different colors and sizes, they are realized in standard lengths of 2 m and 4 m. It is easy to work with them, one side is laid on the adhesive under the tile, and the edges go freely into the second. This allows you to hide cut irregularities, small chips, etc.

Count the inside corners, measure their total length. Do the same with the outside. You don’t need to round anything, the store will sell the standard length. These elements cost a penny, it will not be possible to save on them. Do the same actions around the perimeter of the bath, find out the total length. Do not forget to separately count the number of each type of plastic corners.

If possible, ceramic skirting boards can also be used for bathrooms. In addition to the length, you need to know the number of angles and their type. Professional craftsmen recommend that these skirting boards finish the place where the sides of the bathtub adjoin the wall.

Sum up the length and width of the bath, find out the minimum footage. The fact is that the length of ceramic borders is standard, they will have to be cut to fit their size. Decorative elements are cut on a special disk cutting machine. This is professional equipment, it is quite expensive. It is not economically feasible to buy for finishing one bathtub.

Calculation of the number of floor tiles

There is less work here, everything can be done in a few minutes. How to calculate how many tiles in the bathroom for the floor?

Step 1. Measure the two side walls of the room. There is no more need, the perimeter of the room looks like a rectangle, the sides are the same size. In our case, the length is 3.0 m and the width is 1.5 m.

Step 2 Find out the area of ​​the room. 3.0 m × 1.5 m = 4.5 m 2.

Step 3 If there is no desire to tile the floor under the bathroom, then you need to subtract its area. This can only be done in cases where the bath has a solid decorative screen that hides the lower space. The dimensions of our bath are 1.7 m by 0.7 m, the area is 1.19 m 2.

Step 4. Determine the area of ​​the open area of ​​the bath floor. 4.5 m 2 - 1.19 m 2 \u003d 3.31 m 2. Taking into account the stock, you will need approximately 3.7 m 2 of tiles.

Bathroom tile calculator

To begin with, it is worth noting that the correct calculation of bathroom tiles is the key to a successful, quick and high-quality renovation of the premises. It is for such cases that a special program for bathroom tiles has been developed, thanks to which you can avoid the extra costs associated with the purchase of unnecessary materials.

Variety of programs

The program for calculating tiles in the bathroom is an excellent solution on how to correctly calculate all repair aspects. To date, you can calculate bathroom tiles using a huge number of different programs, which we will introduce you to later.

When choosing a program, pay attention to the number of options and functions that it has.

A bathroom tile design program should include:

• selection of bathroom tiles;
• calculation of the required amount of solutions for tiles;
• selection of the most suitable shade of the tile, its texture, as well as parquet and wallpaper.

Today, the most common programs are "Tile", "Arculator", as well as "Tile 3D". Using the programs is very simple - you need to enter the initial data, after which you will receive the required number of tiles.

Tile calculation program "Tile"

For example, the Tile program today has many versions - it is used in tile salons. The program is intuitive, has simple navigation and control, you can easily create a three-dimensional model of your room according to real dimensions, taking into account windows and doors, plumbing and other elements.

"Arculator" is an original program that will not only calculate the tiles, but also help you lay linoleum, laminate, and make suspended ceilings.

Everything here is not as bright as in the Tile program, but the Arculator calculates more accurately, so you will get the most detailed calculation.

Some of the latest versions of the programs will also help you choose the tiles for the bathroom, taking into account the illumination of the room, as well as its dimensions. The latest option that allows you to design the entire design of the room is 3D tile layout in the bathroom. The layout of the tiles in the bathroom 3d not only allows you to place the position of the future coating, but also makes an accurate calculation of all materials and indicates their average cost. In addition, the calculation of 3D bathroom tiles allows you to look at the already finished room in a three-dimensional image. Thanks to this, you can notice and correct all the defects that we encounter when modeling tiles in the bathroom.

Bathroom tile layout 3d

The ViSoft Premium program should be noted here - this is a great way to design a bathroom with the most accurate dimensions - taking into account all plumbing fixtures and furniture. The program allows you to plan the little things - everything in order to minimize the cut tiles, calculate the cost as accurately as possible and create plans for the room and tile laying in particular. Such a program for visualizing tiles in the bathroom is designed exclusively for an advanced user, therefore, mainly specialists from construction companies work with them.

Self-planning

You can also do the exact design of tiles in the bathroom yourself. The work is quite simple and does not require a huge amount of time.

There are a sufficient number of ways to calculate the required amount of costly materials.

We will describe to you the simplest of them - the layout of the tiles in the bathroom with the help of them will help you in creating the perfect room.

Laying tiles in the bathroom on the floor

For this method of calculation, it is necessary to measure the surface area and dimensions of the tile. For example, the size of the bathroom is 2 meters by 2, and the tiles are 20x20 cm. In this case, the area of ​​​​1 tile is 0.2 * 0.2 = 0.04 m. That is, the number of tiles is 2 / 0.04 = 50 pieces .

To do this, it is necessary to measure the height of the room - 2 meters, the length of all walls 2.5 + 2.5 + 2.5 + 2.5 \u003d 10 m and determine the dimensions of the tile 0.2 * 0.2. Next, we divide the perimeter of the room by the width of the tiles 10 / 0.2 = 50 pieces. We do the same for the height 2/0.2=10 pieces. Next, multiply the result 50 * 10 = 500 pieces. The final step is to convert the number of tiles into square meters, for this we multiply the number of tiles by the area of ​​one piece. 0.2*0.2=0.04. 0.04*500=20. In total, we get 20 square meters of tiled material.

As you can see, DIY bathroom tile modeling is a very easy way, accessible even for non-professionals. We would like to draw your attention to the fact that 10-15% of the material for the reserve of tiles in case of unforeseen situations should be added to the results obtained.

You can also use the tile calculator on the site.

We consider the grout

After laying the tiles on the wall surface, the main thing to take care of is grouting the joints between the applied tiles.

When preparing the grout, the main thing is to correctly calculate the required amount, and for this it is necessary to calculate how much volume will need to be filled.

The optimal seam width ranges from 1.5-3.00 mm, no more, but no less. Plus, to the depth of the seam, which will be approximately equal to the full thickness of the tile, it is necessary to apply a coefficient of 1.5 millimeters. This will help when accounting for tile shrinkage, indoor humidity, and more.

Calculating how much grout is needed in a particular case, you need to divide 1/2 of the perimeter of the tile by its total area, and then multiply by the height of the tile. The result obtained must be multiplied by the width of the seam and by the coefficient. The result will be the required volume in kilograms of grout, which will be needed for one full square (square meter) of coverage. For example, if the tile area is approximately 0.04 square meters, and the joint width is about 2.00 millimeters, then one kilogram of grout is enough for an average of 3.5 square meters.

Calculator

We also want to say a few words about special calculators for calculating tiles. Calculator for calculation - another bathroom tile designer. They were developed to simplify calculations for construction companies. The calculation is as follows: we measure the area of ​​\u200b\u200bthe room, divide the result by the area of ​​\u200b\u200bthe tile. The result obtained by such calculations is presented in meters.

In this article, we introduced you to various ways to calculate the required amount of tiles, the most optimal of which is the program for laying tiles in the bathroom.

Repair work begins with the right choice of technology and the acquisition of appropriate materials. Ceramic tile flooring is no exception.

High-quality tiles in our time have ceased to be a scarce finishing material, and floor cladding is not produced so often as to purchase ceramics for future use in large quantities. Therefore, it is necessary to calculate the tiles on the floor correctly, taking into account the specifics of the technology and the possibility of spot repairing the flooring.

Correct is the calculation of flow with a minimum error, and - only in the big direction. This will save money and save you from an unpleasant surprise when there is not enough material, and you need to at least buy more.

With seeming simplicity, the calculation of the need for ceramics must be made taking into account many factors that affect the consumption of tiles:

• the size and configuration of the room;
• type of flooring (straight, offset, diagonal);
• tile format.

The length and width of the room is measured with a tape measure.

Determination of tile consumption in square meters

Monotonous flooring with ceramic tiles in the form of straight laying, diagonal laying or offset cladding is a common technology. The calculation of the need for tiles in this situation begins with measuring the floor with a tape measure and calculating its area by multiplying the length in meters by the width.

6.3m x 3.1m = 19.53 sq.m.

To calculate in square meters the number of tiles needed to finish this area, add 10% to the resulting value and round the result up, taking into account trimming of products during the sticker process and possible damage to the material.

Floor tile packaging

19, 53 sq.m. x 1, 1 = 21, 483 sq. m. We round up and get 22 square meters. tiles.

The packaging with ceramics indicates how many square meters of material are contained in a box of tiles, for example, 1.1 square meters. Dividing our received consumption value by this value, we get how many packs are required:

22: 1, 1 = 20 packs - the final result of the calculation of the need for tiles. If the value is fractional, then the number of packages must be rounded up to integer units.

Counting when laying diagonally

A diagonal tile sticker allows you to hide the defects in the geometry of the room, which justifies a slightly higher consumption of ceramics when using this type of flooring.

When laying tiles diagonally, 15% must be added to the floor area, since fitting ceramics when fastening in this way generates more substandard waste, and also rounds the result up.

19, 53 sq.m. x 1, 15 = 22, 46 sq. m.

After rounding, we get 23 square meters. facing material, divide by the quadrature of the ceramics in the box and get the amount of tiles, expressed in packs:

23 sq.m. : 1.1 sq.m. = 20.9 packs. We round up and get how many tiles you need to purchase - 21 boxes.

If the room has a different shape (trapezoid, polygon, oval, circle), then the area of ​​​​these figures is determined using the appropriate mathematical formulas, or the floor is divided into simple geometric components (rectangles, triangles), the area of ​​\u200b\u200bwhich must be calculated separately and summarized, and then, taking into account the type of flooring, apply a multiplying factor of 1.1 or 1.15.

When laying tiles diagonally, the calculation is carried out in the same order as with the usual

Piece method for determining flow

Such a calculation of the need for material gives a smaller error and is mainly used when using expensive finishing materials by direct laying or when drawing up an art panel on the floor. When laying ceramics diagonally, this counting method is not applicable.

Let's consider the calculation on a specific example.

Room dimensions: 6.3 m x 3.1 m.

Product dimensions: 0.25 m x 0.20 m.

With the direct method of laying ceramics across the room, the following number of ceramic sheets will fit in the size of its length:

6.3m: 0.2m=31.5 pieces. Round up and get 32 ​​pieces.

The size of the width of the room will fit:

3.1m: 0.25m=12.4 pieces. After rounding, we get 13 pieces.

We multiply these values ​​and get:

416: 10 = 41, 6 packs. Round up and get 42 packs of tiles.

Experts say that piece-by-piece calculation of tiles is more accurate.

Combined demand calculation

In this case, a map-sketch of the floor finish is drawn up, measurements are made of individual sections of the base and the format of the corresponding tile.

First, using the piece by piece method, the amount of ceramics involved in the composition of the panel or ornament in the center of the room is calculated, and then in square meters or piece by piece, you need to calculate how many sheets will be needed to design background sections with monotonous cladding, taking into account the difference in waste between direct laying and laying along diagonals.

Results

Using these recommendations, you can minimize the likelihood of an error in calculating the need for ceramics and save not only on the minimum amount of remaining material, but also on the absence of the need for additional trips to purchase tiles in case of a shortage.
