The range of tiles, which is sold in stores, differs not only in texture and color, but also in size. When carrying out repairs, the owner of the apartment must know how to correctly calculate the number of tiles. Experts recommend purchasing building material with a small margin.
What features should be considered when making calculations?
Area is not the only indicator that affects the number of tiles. There are several important points that the landlord must know:
- The consumption of material depends on the installation method used in the work process. When finishing can use the direct or diagonal method.
- From the total area of the room you need to subtract the space that does not require decoration. For example, in the room you can not lay tiles under a cast-iron bathtub or furniture.
- Tile overruns may be due to factory defects or the need for trimming.
Fragile material can crack or break in the wrong place at any time. In the process of installation, specialists have to achieve the coincidence of the drawings. The situation is complicated by the presence of uneven walls and ledges.
Calculation Methods
To reduce your expenses, you must try to measure the dimensions of the room as accurately as possible. Some elements in the installation process will have to be cut into pieces.
It is often difficult for builders to combine a ceramic pattern. Inaccurate actions can ruin the appearance of the floor.
By area
Before laying tiles, it is recommended to measure the size of the room. In this way, you can determine the consumption of tiles in square meters. In rooms that have a rectangular shape, it is best to use plain grades of tile.
You can measure the dimensions of the floor using a tape measure. The obtained values must be multiplied by 10%, since during laying the material can be damaged in one careless movement.
A room with complex geometry can be divided into shapes that have the correct shape. It can be rectangles, circles, triangles and squares. Do not forget to measure the size of the tile itself.
To understand the features of calculating the number of tiles, consider the following example.
The owner of the apartment decided to use the direct laying method. After measuring the room, the following parameters were obtained:
- The width of the room on which it is planned to lay the tile is 200 cm.
- The length of the room is 300 cm.
The owner decided to lay the tiles with dimensions of 20 × 15 cm on the floor. Now we use a simple formula:
D / d1 x S / s1, where;
- D and S - length and width of the room;
- d1 and s1 are the overall dimensions of the tile.
300/20 = 15 pcs.
200/15 = 13.3 pcs.
Now you can calculate the total number of tiles.
15 x 13.3 = 200 pcs.
When laying diagonally
For laying tiles in rooms with uneven walls, you can use the diagonal method. The disadvantage of this method is to increase the consumption of material by 15%.
During the installation process, specialists are faced with the need to cut tiles to a given size. In a room with a complex configuration, it is quite difficult to calculate the amount of material.
First you need to determine the floor area on which the tiles will be laid.
The total area of the room must be multiplied by a factor of 1.15.
For example, the owner of the apartment decided to lay the tiles in a diagonal way. The floor area is 19.53 m.
19, 53 sq. M. x 1, 15 = 22, 46 sq. m
Advice! Do not forget to round up the obtained values upwards, as the preparation of ceramics will be accompanied by the formation of substandard waste.
By the number of rows
The method consists in determining the number of rows of elements on which the finishing material will be laid. To get the desired value, divide the width of the room by the width of the tile. The resulting figure must be rounded up, since during the installation process some elements will have to be cut off.
Piece method
Before buying expensive tiles, it is recommended to use the piecewise method of calculating the amount of material.
The procedure can be divided into the following steps:
- First you need to measure the length and width of the floor area on which you plan to carry out repairs.
- After this, it is necessary to measure the dimensions of the tile.
- The layout can be pre-drawn on graph paper.
As an example, consider the following case. The owner decided to lay the tiles in the bathroom. After measuring the room with a tape measure, the owner received the following indicators:
- length 1.75 m;
- width 1.7 m.
The bathroom has a rectangular shape, without protrusions and niches. For laying, it is planned to use tiles with dimensions of 33x33 cm. To calculate the area of the room, we multiply 1.75 by 1.7 m (2.975 sq. M). Round the resulting value to 3 square meters. m
Now divide the width of the room (1.7 m) by the size of the tile (0.33 cm).
170 / 0.33 = 5.1 pcs.
In the same way, we calculate the number of tiles taking into account the length of the room.
175 / 0.33 = 5.7 pcs.
After rounding, multiply the obtained values.
5.1 x 6 = 31.6 pcs.
To lay tiles in the bathroom, you need to purchase at least 32 tiles.
Combined method
The need to use a combined method arises in the case of laying different types of tiles. To more accurately determine the amount of material, it is recommended to draw up a laying pattern.
Online calculator
To facilitate the process of counting the number of tiles, you can use the online calculator. This method is suitable for rooms with a standard shape.
The benefits of using online calculators include:
- The ability to verify the correctness of manual calculations.
- Buyers do not need to do mathematical calculations on their own.
- Similar systems can be found on the websites of companies that sell building materials.
- Thanks to the scripts, you can quickly determine the amount of tile that will be needed to finish the apartment.
Online calculators have several disadvantages:
- Users encounter errors in the calculations.
- Developers cannot put parameters into the formula that take into account all the features of the room.
Often the room has a non-standard layout. In this case, it is recommended to clarify the size of the room. After entering indicators, the script automatically determines the number of tiles that are needed for finishing work.
