Starting repair work, first stipulate the amount of necessary building materials: glue, wallpaper, paints and varnishes. To make such calculations and not to get too much or not enough consumables, first you determine the area of the room. Such a concept will be required not only for repairs, but also for the sale of real estate. How to calculate the quadrature of the room, get and put into practice the collected data, we will try to understand.
Calculation Features
If the question arises, how to correctly calculate the quadrature of the room, start from what types of work will be done.
To find out the necessary data, you have to apply the formula. The calculation is carried out taking into account the shape of the room and the presence of additional structures in it: loggias, niches, arches, lintels, walk-in closets.
The square of the room is not only the floor area. Therefore, when posing the question of how to calculate the quadrature of a room, it is necessary to build on future work.
So, when plastering, S walls and ceilings are calculated, and for tiling the kitchen with tiles, it will be necessary to calculate the floor area and wall surface to a height of 1.0-1.5 m. During the operation, difficulties may arise if the design of the room is complicated: there are beams, niches or alcoves, especially if they are located near window openings.
It would be a mistake to think that S floors and S ceilings are equal. In the attic, for example, roof slopes hang overhead above the head, forming the so-called tented ceiling. It is immediately noticeable that the square of the floor covering will be larger. Therefore, proceeding with the repair in the under-roof space, the area of each surface is calculated separately.
Calculation of the quadrature of a rectangular room
In a standard room, the floor is always equal to the ceiling and is calculated according to the formula for the rectangle S = AxB.
When covering with gypsum plasterboard panels, wallpapering, plastering, painting walls and / or ceilings, tiling with tiles and other types of repair work that require leveling and wall covering, area calculation is required.
All calculations are based on the perimeter and height of the room. Having measured them with a tape measure, substitute in the formula:
S = PxN , where H is the height of the room, P is the perimeter. Formula P = 2 (A + B), where A and B are the length indicators of adjacent walls.
Do not forget about window and doorways that do not fit into the finish. Their area must be taken away from the total number.
Therefore, before calculating the quadrature of the room for wallpaper, all window openings are measured, after which the area of each is calculated, summed and subtracted from the S room , resulting in a quadrature for decoration.
Important! Remember that for door and arch structures, the formula for the circle segment or for the semicircle is additionally used.
How to get a measurement result
How to calculate the quadrature of a room? Measure the walls first. To do this, use regular roulette. For a square shape, the formula is suitable:
S rooms = AxB (A - length; B - width).
* Width is multiplied by height, after which a number is obtained that reflects the area of the room in m 2 .
Putting the formula into practice
Problems should not arise if you know how to calculate the quadrature of a room. Try to understand the features of calculating the area of a room for wallpapering in more detail, according to an example.
Often, after the completion of repair work, excess material remains. Or at the end of the pasting, it turned out that the canvas of the wallpaper was not enough. When planning the finish, do not forget about the exact and correct calculation of the area of the room. So you save yourself from uncomfortable situations in the process of wallpapering.
How to determine how much wallpaper is needed?
It all depends on the perimeter of the room and the width of the roll. Having these data in a notebook, it is not difficult to calculate the cubic capacity. When working with such material, consider its drawing.
The easiest way is to paste over the wall with segments with a simple image: the paintings do not have to be customized. If you purchased rolls with complex geometric patterns, get ready for more material consumption, because the pieces will have to be cut so that the elements of different cuts fit together to form a single whole.
Important! Regardless of the texture and style of the canvas, always add 2-3 centimeters to the skirting allowance.
Counting wallpapers: how to figure it out?
Consider an example. With a perimeter of 12 m and a standard roll width of 53 centimeters, 23 strips of wallpaper will be needed to wall the walls.
Important! When sticking overlap do not forget to take into account allowances.
If the ceiling height in the room is 2.7 m, add at least 5 cm to the allowance. This results in a length of 1 sheet - 2.75 m. With a standard length of material in a roll of 10.05 m, 3 whole strips come out of one package. To calculate the number of rolls, 23 are divided by 3 and get the number of packages necessary for finishing - 7.54, that is, you will have to purchase 8 rolls of wallpaper.
Bathroom cladding: how many tiles will be needed
We will analyze the calculation of the required amount of material using an example. Masters use a proven methodology for calculating the volume of consumables for decorating a bathroom.
To do this, measure the walls and calculate according to the formula in order to calculate the quadrature of the bathroom. Here, as in calculating the required number of wallpapers, door and window openings are subtracted from the total area.
Consider an example. So, having received a number of 21 square meters, they find the required number of tiles. First, they calculate the area of 1 ceramic product, with a size of 0.3 x 0.2 we get 0.06 m 2 .
S bath / S products = n, where n is the number of tiles.
21 / 0.06 = 350 pcs. The stock when laying products is 10% of the required number. For example, 35 pieces. As a result, it turns out that for the lining of the bathroom you will need 385 whole tiled squares.
Important! The amount of flooring is determined according to the same scheme.
Now you know how to calculate the square of a bathroom under a tile, for wallpapering or for installing flooring.
Using a simple formula, you can independently determine how much finishing material, adhesive mixture, screeds will be required to carry out repairs in any of the premises of the house. It is convenient and simple, because there is no need to hire specialists for such a simple job.
