Calculation of the number of tiles. How to correctly calculate the tiles on the floor: three reliable ways. Additional elements on which the tile is laid

22.11.2019

Bathroom finishing - difficult process. Except technological subtleties There is still a design problem. Bathtubs, toilets, combined bathrooms are usually tiled. But how to plan its placement on the walls so that the finish is beautiful? For those who decide to do the repair themselves, there is a good way out - to use the software. There are special programs for laying out tiles, there are such sections in general construction or design software, and there is also an online service from large manufacturers and stores selling finishing materials. About them and will be discussed further.

Tile 6.0

A specialized program for laying out tiles and wallpapers. There are three versions: Home for home use, Profi - for professionals, Profi + Render - professional with advanced functionality. For independent design creation, Kafel 6.0 Home is suitable, but it is not free - 1000 rubles per month of use. All of them can be purchased on the campaign site tile3D.com. Naturally, there are hacked copies, but it is difficult to say how safe it is to download them.

The current version of the program is good: even a truncated home version allows you to create three-dimensional projects (3D) and receive calculations for necessary materials(except for whole and cut tiles, it counts the amount of glue and grout for joints). What else can she do?

Take into account door and window openings, columns, arches and other curved surfaces.
It is possible to add new tiles to the directory, save them for future use.
Tiles can be installed and moved at any angle.
You can add 3D images of other objects (bath, shower, etc.) by specifying their coordinates.
The program calculates tiles and Supplies, but in the “home” version you can’t print them, but you can write off the screen or take a screenshot and print them as an image, not a table.

In addition, you can change the degree of illumination, gloss and relief of the tile. All these settings can be done for each individual object. Another good thing is that the site has tutorials on working with the program, where the creation of a project is described step by step. It is easy to work in the program, the interface is clear, mastered from the first time. Of the shortcomings of the home version - you can not get a scan on the walls, which is quite inconvenient. In general, the program is good, but not free.

ViSoft Premium

This is a specialized bathroom design software for professionals. One of the functions is tile layout. In base big number samples - almost 39 thousand types of tiles from different manufacturers (at the time of writing, there are 362 of them). The layout project is developed on the basis of samples that are in the database; new ones cannot be made.

Here is a summary of the features of the program:

The selected tile samples are automatically placed on the specified area.
It is possible to view other layout options.
To create a bathroom interior, you can choose plumbing from a huge database. In this case, the sets are generated automatically. If necessary, they can be corrected.
During the creation process, the project can be deployed in any direction, evaluating the result from different points.
Take snapshots of the result.

There are two modes of operation: drawing and sketch. Drawing mode creates a black-and-white image, which can later be “filled” with different colors. Sketch mode - immediately with color.

Ceramic 3D

Good professional bathroom design software. Naturally, it is not free, but there is a demo version with full functionality, which is available to everyone without payment. The free license is valid for 1 month. If you decide to make the layout of the tiles for yourself, this is a good option, but you must meet the deadline.

Ceramic 3D program - there is a demo version for a period of 1 month, it is free

Ceramic 3D allows you to quickly create projects: each operation takes about 2-4 seconds. So that simple projects They are “built” in 5 minutes, complex ones take 15-20 minutes. Here is the feature set:

creation of premises of any configuration according to the exact dimensions, including attic rooms;
easy drawing of niches, shelves, ledges, boxes of any configuration;
the ability to create a tile outline of any shape (polygonal, rounded, etc.);
drawing columns and their finishes;
saving laying patterns of any complexity;
replacement of the contours and dimensions of the room while maintaining the layout;
the possibility of creating stairs and their decoration with tiles;
automatic calculation of the number of tiles.

In general, Ceramic 3D is not only a tile layout program. In it, you can create the overall design of the bathroom and work out the design of other elements or parts of the room that involve laying tiles. It's nice that detailed lessons are attached to the program, with which it is easy to master.

Compass-3D LT

This is a free version professional program for three-dimensional design of various objects and details, created by the Russian company ASCON. So it's not just a tile layout program. This is just one small part of it. The Compass-3D LT version is an introductory version that allows you to master volumetric modeling and planning. Complete with the program are training materials - video and graphic examples.

Compass 3D in the light version has a very limited functionality, but it is more than enough for laying out tiles. To plan the layout of the tiles during installation, a package with a building configuration is loaded (there is also a machine-building one). The base and build package will require about 3.5 GB of disk space.

With this program you can:

make a site plan;
design a room using different finishing materials and evaluate the result in the form of a three-dimensional picture;
develop unique decor items and get their drawings;
after completion of the project, receive drawings with dimensions.

In general, the program is multifunctional even in the free version. At the same time, you can learn the basics of designing in 3D.

A simple program for laying tiles without special effects - Arculator 7

If you do not need a three-dimensional image, but you need to look at the layout, and even calculate the amount of material without errors, pay attention to the Arculator 7 program. It is designed to calculate materials for interior finishing work. That is, with its help, you can accurately determine the required amount of tiles, wallpaper, laminate, etc. It is also possible to calculate the amount of materials for ventilated facades. Pleasant surprise: this tile layout software (and more) is free.

What can be done in it:

Create surfaces of any size and shape, expose openings of any shape on them.
The position of the tiles can be adjusted, deployed at any angle.
On the same surface, objects of different sizes can be located in different directions.

Learning not to work is not a problem even for not the most “advanced” user. The interface is clear, the requirements for the computer are very modest, it takes less than 1 MB on the disk. A great option if you only need a layout, and not a design development with the arrangement of plumbing, furniture, etc.

What else can you work with?

In addition to specialized programs, there are many software, designed for planning other objects, but in which there are sections for laying out tiles. If you have experience in one of them, it will be easier to work with a familiar interface than to master a new one. Here are some general building or furniture programs in which you can draw tiles.

AvtoCad (AutoCad) is a general construction program with wide functionality (there are 2D and 3D).
NanoCad is an analogue of the one described above, but the development is Russian. The basic version is free.
PRO100 (PRO100). The program is designed for the development of furniture, but there is a solid section for designing the layout of tiles, laminate, wallpaper. Many people say that it is easier to work in it than in AutoCAD.
SketchUp is a program for designing rooms and furniture, there is a section for tiles, but the functionality is small and difficult to work with. In addition, you have to manually recalculate the quantity, since errors in the calculations are not uncommon.

Of course, this is not specialized software and it is not so convenient to work with them. But if you have already worked in them in other sections, it will be easier and faster to figure it out than learning to design in a new program.

Online tile laying programs

Most large online stores selling tiles or manufacturers provide the opportunity to create online free of charge own project. The peculiarity is that basically you can work only with those collections that are on the resource. You cannot enter your own data into such programs.

They work on the principle of browser games - you do not need to download and install them. You work through the browser on the campaign resource. The procedure for creating a project is standard: select or draw a plan of the room for which you need to create a tile layout, select a collection (from those that are on the site), then create a layout. Based on the results, a statement is usually formed: how many tiles are needed, you can also print or save the layout that you made in the form of a sweep along the walls.

Why and how to calculate the tiles in the bathroom? This is necessary to purchase the required volume of building materials: you will not overpay for unused material, and the money saved can be spent, for example, on buying tile adhesive.

Calculation of tiles for bathroom walls

We calculate the area. Measure the perimeter of the room and multiply it by the height of the walls. For example, the height of the room is 2.7 m, the width is 2.5 m, the length is 3 m. Find the perimeter: 2.5 + 2.5 + 3 + 3 = 11 m. Multiply the perimeter by the height: 11 × 2.7 = 29, 7 m2. From this number, the area of \u200b\u200bthe door and windows, if any, is subtracted. Suppose, after subtracting, an area of \u200b\u200b28 m2 was obtained.
Find the area of 1 tile. For example, the dimensions of one tile are 0.3 × 0.2 m. Then its area is 0.06 m2.
Find out the number of bathroom tiles. The area of the walls is divided by the area of one tile: 28 / 0.06 = 467 pieces. 10% stock is another 47 pcs. The total number is 514 tiles.

How to calculate the number of tiles per floor

The mathematical calculation of the number of tiles per floor is similar to the algorithm described above:

Finding the floor area.
Divide the floor area by the area of one tile.

Common Questions

How to calculate the number of bathroom tiles if it is placed diagonally on the floor or wall? In this case, the calculation algorithm is no different.
What to make a margin when calculating bathroom tiles? The allowable stock of a tile from its calculated quantity is 10%. Buying a larger volume of tiles is unreasonable for reasons of economy, less is risky, because you also need to take into account the seams for tile grout.
How to calculate how many tiles are needed in the bathroom if the floor area is partially covered by a bath or shower? Just subtract it from total area gender.

As you can see, simple calculations allow you to find out how many tiles you need in the bathroom. The calculation principle is also relevant for

August 18, 2016
Specialization: master of internal and outdoor decoration(plaster, putty, tile, drywall, lining, laminate and so on). In addition, plumbing, heating, electrical, conventional cladding and balcony extensions. That is, repairs in an apartment or house were done on a turnkey basis with all necessary types works.

To begin with, you can use the bathroom tile calculator, but I will warn you right away - this will give you the most inaccurate result. And all the flood that such programs are not able to take into account the nuances.

However, making such calculations yourself is easy and simple, and they will be the most accurate, up to one unit of a tile (although a couple of extra pieces will still be needed in reserve). I suggest you study a short course of study, more precisely, an understanding of the very principle of calculation.

Calculation of tiles according to the size of the room

What to Consider

In a room with the same quadrature, a different amount of material may be needed. Therefore, the question of how to calculate the number of tiles in the bathroom also depends on the number and location of plumbing units and pipelines.

There are several nuances that you should pay attention to, since it is most accurate to calculate how many tiles you need in the bathroom, you can only take them into account. First of all, in order to understand how to calculate the area of \u200b\u200ba bathroom for tiles, you need to accurately determine the installation of plumbing fixtures and the size of the tile itself.

Let's get started with this:

the very first thing you need to consider is how the tile will look in those places that are most visible. As a rule, they are located under the ceiling (top row), as well as above the bathrooms, for example, above the bathroom;
but here the catch is that you can set the height of the same bath arbitrarily, but changing the height of the ceiling is much more difficult. Therefore, the focus should be on the level of the ceilings;
under the ceiling, even if they are suspended, it is desirable to have a whole, uncut row. So, the calculation of the number of pieces vertically should come from there;

this means that we measure the number of tiles from the stream to the first row (usually, these are 8 pieces of tiles 200 × 300 mm), and leave the bottom row for later;
but it also happens when you can fit into an integer number of tiles, then you can also make an uncut row above the bathroom, as shown in the bottom photo;

on the walls where the bathroom will be pressed, calculation tiles you shouldn’t do it for the bathroom - you can leave an empty space there, since no one needs cladding in an inconspicuous place;
the same can be said about the tiles on the floor - tiles are not needed under the bathroom and no instructions require them to be installed there. The bath fits perfectly on the screed, especially since it is easier to adjust its height ;
some also save tiles under the cabinets, but I don’t advise doing this, it’s too “slippery place” - after all, the doors open and everything is visible there;
another point in the question of how to calculate the tiles more economically is a shower cabin or a box, although I don’t quite understand the point of installing a box in a tiled room - this is just an absurdity or a thoughtless waste of money;
under the pallet, tiles are not needed, but it depends on the desire of the owner (the area is small), but why put a box where you still need to put tiles on the walls, since they will be noticeable ?! I repeat once again - this is absurdity and it is unlikely that anyone will find arguments to convince me otherwise;

one more thing, how to calculate the consumption of a tile, is the presence or absence of it on, but there usually the calculation is clean, without any resets;
and finally, these are boxes that can be in any bathroom, although again I think that they a large number of- this is the negligence of a plumber. They are needed only where vertical or horizontal pipe impossible to hide in a shtroba.

Calculation examples

As they say in Odessa: “What will I get from this?”. In our case, it means how to correctly calculate the tiles for a certain layout of plumbing units? Let's start with the total area.

Imagine that our area has 3.0 × 2.5 m - this, of course, private house, but for example there is no difference. We will take the height of the walls to the draft ceiling 2.6m, therefore, we will get the whole room 3.0 × 2.5x 2.6m. The cubic capacity will be of little interest to us, since the tiles should be counted according to the area.

Again, let's move on to abstract images and by default we will take a 200x300 mm tile, since it is used most often. We will have spacer crosses with a thickness of 3 mm (also the most popular).

I will say right away that the thickness of the seam should not be taken into account - this, of course, also applies to determining the quantity, but even the most experienced tiler can have force majeure. Any of the tiles may fall and break, or simply burst when cutting.

Then one row will require 3000/200 = 15 pieces exactly. But here, for symmetry, you need the width of the seam. This means that between fifteen pieces you will get 13 seams of 3 mm, in total, 13 * 3 = 39 mm (we consider 40 mm). This means that the extreme tiles will need to be cut 2-3 cm each, leaving 180 mm each, although their number will remain the same - 15 pieces.

Next, we move on to the vertical - everything is calculated in the same way. And if we have a room height of 260 cm (2600 mm), then we need 2600/300 = 8.6 pieces for this. That is, the first row will be slightly more than half. A little wrong!

The price of the material will decrease if we make the correct calculation:

first, we have seams;
and, secondly, it is not necessary to put the tiles right up to the ceiling, because there will still be floor tiles below.

Therefore, the number of copies can be reduced to 8.5 pieces, then the bottom row will go one for two. So, at the bottom you will need not 15, but only 8 pieces!

Now, let's define areas that can be skipped, especially if it's an expensive tile, like 3d. Since it is not needed under the bathroom, then its quantity can be calculated from the total quadrature. For example, let's take a bathtub with length/width/height dimensions of 1700x700x570 mm (this is an ordinary standard bathroom).

So, if we have a height of 570 mm, then the row of tiles above the bathroom will start (third row 150 + 300 = 450 mm) from 570-450 = 220 mm, that is, almost from a whole row.

We do the same with the end and side in width - we calculate the absence of tiles on this segment. If you want to tile the bathtub, and not install a plastic screen there, then you should not do such calculations - everything will remain in place.

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 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 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 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.

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 done 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.
