How to calculate the number of tiles for finishing the floor?
The calculation of the required number of tiles for a flooring device is the easiest. For him you will need to know the following values: the area of one tile from the collection chosen for finishing the room, and the area of the floor itself. To calculate the floor area, you need to measure its width and length, and then multiply these values. To calculate the area of one tile, you should multiply its length and width, respectively. After that, the floor area is divided by the area of one tile element.
As a result, you will find the desired value: the number of tiles you need in pieces. If the number is obtained fractional, it should be rounded up. Example: if the length of the floor is 4 m and its width is 2 m, then the floor area is 4 mx 2 m = 8 m2.If the dimensions of the selected tile are 0,4 m and 0,3 m, then its area will be 0,4 m х 0,3 m = 0,12 m 2.Then the floor area is divided by the area of one tile - 8 m2 / 0.12 m2, resulting in 66.66.We round this number upwards. As a result, you will need 67 tiles for finishing the floor.
This calculation is basic and ideal. It does not imply that you will cut the tile or spoil it, but such situations are the norm. That's why experts advise buying material with a margin of 10%.So, 10% of 67 tiles will be 6.7( rounded to 7).Accordingly, all you have to buy 74 tiles. Problems can arise even when the room has a complex configuration, rather than the shape of a rectangle or square that is convenient for calculation. In this case, the room is divided into several simple figures, the area of each of them is calculated, and the values obtained are summed. Then the calculation proceeds according to the already known scheme.
Calculating the number of tiles for the walls of the room
In principle, if you plan to purchase a tile of the same color for the walls, you can follow the scheme for calculating the amount for the floor. However, most often for the decoration of walls used tiles of different tones, which is diluted with decorative borders and other inserts. This somewhat complicates the task. First, you will need to know the number of rows of tiles from floor to ceiling, and secondly - the number of finishing elements in them. A good piece of paper will be a piece of paper in a box on which you schematically display the alternation of different shades of tiles and denote the rows of curbs.
To determine the number of horizontal rows of finishing material on one wall, it is necessary to measure its height and divide this result by the height of one facing element. The result is the number of horizontal rows of tiles on this wall. For example, if the height of the wall is 2.6 m and the height of the finishing element is 0.4 m, then your wall will be decorated with 2.6 m / 0.4 m = 6.5 or 7 rows of tile( rounding the result upwards).Thanks to this simple calculation, you can more accurately determine the future pattern on the wall and the alternation of tiles on it.
Many large stores or salons offer to calculate the amount of lining material you need with a special computer program.
At the same time, all your wishes regarding wall decoration are fully taken into account. Such a calculation is very rarely inaccurate, but if you doubt it, you can additionally calculate the number of tiles manually, and then compare the results. Then you need to determine the number of finishing elements in one horizontal row. For this purpose, the width of the wall is measured and is divided by the width of one finishing element. So, if the width of the wall is 3 m and the width of the selected tile is 0.3 m, then its number for one row is 3 m / 0.3 m = 10 pieces. For convenience of calculation, the rows of the same tiles can be added together.
As for the doorway in the room, it is necessary to measure its height and width, calculate the area( multiply the values found).The obtained area is divided into the area of one finishing element. The result is the number of tiles, which should be subtracted from the required amount of material for the entire wall. In doing so, do not forget to round up the fractional values in the larger side! In addition, the final amount of material should be increased by 5-7%, which will go to bleed.
How to calculate the required number of tiles for non-standard masonry?
The above methods of calculating the amount of finishing material for floor and wall decoration are suitable only for those cases when the "seam in the seam" is being laid, that is, when the tiles are stacked strictly in line under each other. However, in order to create an original interior, more complicated methods of laying ceramic tiles are often used - "rip-off", "herringbone", etc. How to be in this case? Again, take up the pencil. On a millimeter or a piece of paper in a box, it is necessary to draw the floor of the room being decorated or one of the walls at the most convenient scale. To do this, the perimeter of the room is calculated and the dimensions of the tile chosen for finishing are determined.
Then on this sheet of paper, focusing on the scale, you should accurately depict the pattern of tile masonry. Different icons mark the whole elements of decoration and those that will be cut off. Then you need to calculate how much and what tiles you need in the end. Do not forget to increase this quantity by 10% to avoid unforeseen situations. Thus, an attentive approach to the calculation of the required number of tiles for finishing the premises will make it possible to rationally spend not only money for its purchase, but also time for laying.
