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 bathroom finish, when the same type of tile laying is used for facing all surfaces (straight, diagonal or offset), the need for tiles is calculated in square meters or piece by 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 doorway in meters to the nearest centimeter, rounding down fractions of a centimeter. 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 required amount 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 repair 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 doorway has dimensions of 210 x 80 cm. Its height will fit 210:20 = 10.5 pcs. 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, usually desired views ceramics are already scheduled for purchase, and the format facing material, which will get off the bathroom, 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 the 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.

Depending on the specific type, the cost of ceramic tiles can reach high values. Its rational use is one of the options for reducing costs. finishing works. Correct calculations needs -effective method saving 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 in the execution of any construction works, 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 plumbing 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 outside corners, at the junction of the wall and floor. Have different color and dimensions 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 up internal 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

Tiles are usually sold in square meters. For order floor tiles it is quite enough to know the footage of the room: if you have a kitchen area of ​​​​10 square meters. meters, then you will need to order 10 m of tiles + margin for trimming and fighting (usually around 10 percent).

However, sometimes you want to imagine exactly how many tiles will go to each meter. If you just want to imagine this number in order to visualize the picture (how much will it take per meter: 4, 10 or 20 tiles), then it is very easy to do. If you need to calculate the exact number of tiles in pieces that you will need to buy in order to lay out a square meter in your room, then this is a bit more complicated. (These two values ​​may be slightly different, yes)

Let's start easy: how many tiles per square meter(any meter, completely abstract)

Calculate the area of ​​a tile

First you need to calculate the area of ​​​​one tile in square meters. For this, her length(in meters) multiply by width(in meters). It is better to multiply in meters, and not in centimeters, so as not to get confused with the conversion of square centimeters to square meters)

For example, let's take a 20x20 cm tile. Since there are 100 centimeters in one meter, 20 cm is 0.2 meters (20/100 = 0.2). We multiply the length by the width 0.2m x 0.2m = 0.04 sq.m. Thus, a 20x20 cm tile has an area of ​​0.04 sq.m.

If the tile is 30 cm by 60 cm, the calculation gives 0.3 m x 0.6 m = 0.18 m2. For a 12.5 cm x 120 cm tile, the area will be 0.125 m x 1.2 m = 0.15 m2.

Counting the number of tiles

Knowing the area of ​​​​one tile, it is enough to divide 1 square meter by this area to get the number of tiles. For a 20x20 cm tile, the calculations will be as follows: 1m2 / 0.04m2 = 25. Thus, there will be exactly 25 20x20 cm tiles in a meter.

For a 30x60 cm tile, the results will be 1 / 0.18 \u003d 5.555 (5). Approximately five and a half tiles.

It is important to understand that this value is indicative, calculated. In reality, a different number of tiles may go per meter. Let's see why.

Let's say our room has dimensions of a meter by a meter (that is, the most square meter of the area), and the tiles have dimensions of 30x60 cm. According to preliminary calculations, we needed 5 and a half tiles, right? In reality, we may need 7 tiles

Why is this happening? Because the calculations consider the entire area of ​​\u200b\u200bthe material as a whole, as if we poured it or laid it in tiny pieces. If desired, of course, scraps from tiles 4, 5 and 6 can be used to cover the area of ​​the seventh tile. This is quite enough, as the calculations show. But the length of the remaining pieces is less than necessary (they are 20 cm each), so all this will look doubtful.

Bad news, we will most likely need eight tiles. We want the tile to look nice, small pieces not very aesthetically pleasing, so let's align it in the center.

Well, you can decide that the whole trouble is that we took a large tile of the wrong size (30x60 cm) for such small footage(1 sq. meter). No one does this, you need to take a small tile. Okay, let's take a 10x10 cm tile. What can happen to it? It would seem, nothing. Exactly 100 pieces of such tiles are placed in a square meter (1 / 0.01 \u003d 100).

Here and no.

The fact is that a square meter is not necessarily a square room measuring a meter by a meter. It can be a narrow corridor measuring 2 meters by 50 cm. Worse, it can be a passage with exact dimensions of 57 cm by 1.76 m. Non-multiple 10 dimensions will instantly give us waste. As a result, 108 tiles will go to the area. 18 horizontal, 6 vertical.

Of course, as the footage increases, the percentage of extra tiles usually decreases. In any case, before calculating the number of tiles, decide for yourself for what purpose you need it: just for orientation or for ordering. If for an order, and you want to count the number of tiles to the nearest piece, you cannot divide the area of ​​\u200b\u200bthe room by the area of ​​\u200b\u200bthe tile. You need to either draw and see, or divide the length of the room by the length of the tile, the width by the width and decide how you can combine the leftovers.

Many rooms in a house or apartment are traditionally or at the request of the owners tiled with ceramic coating, and it is very important to know how to calculate how many tiles you need.

If you are going to make a beautiful apron in the kitchen, laying it out of pastel-colored tiles, you can literally calculate the amount of material on your fingers, only having decided on the number of rows. In this case, most likely, it will be possible to completely avoid any costs, especially if you use square tiles. However, with full wall or floor cladding, certain difficulties arise. The fact is that in addition to the main type of tiles, there are also curb ones. Ceramic elements are not only square, but also rectangular, as well as multilateral and figured, with a complex patterned contour.

Provided that the first two types of form factor are laid in even rows, it will be quite easy to correctly calculate the number of tiles for a kitchen or bathroom. It is enough to know the square of the surface to be finished and the area of ​​the ceramic element to determine how much material is needed on the walls or floor. But it is not always preferred the simplest scheme cladding, it is enough to include a couple of borders in it, and the calculations will become much more complicated. Another problem will be added when tiles of different formats and all kinds of decorative elements are included in the decoration.

You will face certain difficulties if you want to lay out the floor or walls with different types of multifaceted ceramic elements. The geometric pattern will turn out beautiful, but to determine the required number of details, you will have to calculate the area of ​​\u200b\u200beach figure, as well as determine the percentage of its content in the overall composition. The same applies to tiles with a complex contour, here the task is complicated by the fact that for a shape that is far from geometric, it is rather problematic to calculate the area. Add to any of the options the presence of plumbing and communications in the room, as well as lighting on the walls, and it will become clear that for each individual case you need to look for your own approach, how to calculate the tile.

The shape of the bathroom, and in some cases the kitchen, is not necessarily perfectly rectangular. Therefore, be prepared by dividing its gender into simple geometric shapes. For the most part, it will be all the same rectangles and triangles. But in standard version, when the lengths of opposite walls are equal, and all angles are 90 degrees, it is enough to multiply only 2 values ​​\u200b\u200b- the dimensions of adjacent sides.

Then, having found out the quadrature of the surface, we determine the area of ​​\u200b\u200bthe tile, and since we are looking for the simplest version of the cladding, we have a rectangular tile and it is enough to multiply its adjacent faces. Thus, the easiest way to calculate ceramic tiles for a floor is to apply the formula N = (AB) / (ab). Here N- amount, A and B- adjacent walls of the room with a common angle, a and b- adjacent sides of the tile.

It is possible to determine the amount of material by the area of ​​one ceramic element for tiles of any regular geometric shape, for which there are corresponding formulas.

Suppose you decide to decorate the bathroom with cladding using not only ordinary tiles, but also borders. In addition, for greater effect, it was decided to lay, alternating rows ceramic elements with the same width but different height. In this case, even if only 2 different sizes are involved, it will not be possible to determine the total amount of material, taking into account the borders, using the above formula. Therefore, we use another method, which, however, begins in the same way as the first one - by determining the quadrature of the surface to be lined with the deduction of the area of ​​​​the door and (if any) window opening. To count the material on the floor, it is enough to know its length.

Next, you should take all the elements that will be located in alternating rows one above the other and lay them out in a vertical column for the entire height of the finish. We determine the total area of ​​\u200b\u200bthe tiles, taking into account the gaps that are allocated to the seams, and then divide by the result the quadrature of the surfaces to be trimmed and find out the required number. However, this method is not ideal, since small errors occur: where the window and the door are located, only the tiles will remain in the columns, laid on the lintels and the wall under the window opening. Therefore, you can use a slightly different and more accurate method.

We determine the perimeter of the bathroom or kitchen minus the door and window opening. We divide the resulting value by the width of the column into which we have folded tiles of different heights. Thus, we learned the number of rows in that part of the room where there are no openings. For jumpers above the door and window, as well as for the section of the wall under the latter, we lay out the columns and count their number on these segments separately. Further, it will not be difficult to determine the amount of material of each individual size by folding similar tiles in one vertical row and multiplying by the number of columns in the perimeter.

The walls and floor look very nice, on which they laid ceramic tiles with a figured contour. However, it is difficult to come up with enough reliable way correctly calculate patterned tiles. And indeed, if there are no edges, and the contour is various smooth or sharp bends, alternating with all kinds of angles, it is almost impossible to calculate the area of ​​the facing element.

It is very good if the manufacturer indicated on the packaging how many square centimeters on the finished surface the tile will cover. But such information may not be available if you were not interested in advance. Therefore, the only available way is to practice drawing. First you need to take paper in a box, or better - graph paper. We draw on it an exact plan of the room where the decoration will be performed, on a convenient scale. And then we carefully depict, also in due proportion to the real size, a curly tile. We draw the cladding according to the scheme you have chosen.

If all the elements are of the same color, then upon completion of the drawing, you are unlikely to have a question about how to calculate the tile, it will be enough to count the tiles piece by piece. Separate fragments are counted in pairs, taking each for a whole facing element. However, it may be that for finishing you want to use 2 or even 3-4 colors of tiles. In this case, we turn the plan of the bathroom or kitchen into a coloring book, marking on it where this or that tinting will be located. Next, we count the monochromatic elements, and thus find out how many assorted tiles are needed on the wall or floor. This method also suitable for determining the amount of material in complex mosaic laying of conventional rectangular ceramic elements when using a large number colors.

Production repair work begin with right choice technology and the acquisition of appropriate materials. Floor finishing work ceramic tiles are 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

This calculation of material requirements gives a smaller error and is mainly used when using expensive finishing materials by direct laying or when drawing up an artistic 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.

At direct way laying ceramics across the room in the value of its length will fit the following number of sheets of ceramics:

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 required 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.
