How to calculate the square of a room: tips of the master

Starting repair work, first specify the number of necessary building materials: glue, wallpaper, paints and varnishes. To make such calculations and not to purchase too much or not enough supplies, first determine the area of the room. This concept will be required not only for repairs, but also for the sale of real estate. How to calculate the square of the room, get and apply the collected data in practice, try to understand.

Features of the calculation

If the question arises, how to correctly calculate the quadrature of the room, and build on what types of work will be done.

To find out the necessary data, you will have to apply the formula. The calculation is carried out taking into account the shape of the room and the presence in it of additional structures: loggias, niches, arches, jumpers, wardrobes.

The room's area is not only the floor area. Therefore, when raising the question of how to calculate the square of a room, one must start from the forthcoming works.

So, when plastering S wall and ceiling are calculated, and for tiling the kitchen with a tile you will need to calculate the floor area and the wall surface to a height of 1.0-1.5 m. When carrying out the operation, it can be difficult if the structure of the room is complex: there are beams, niches or Alcoves, especially if they are located near window openings.

It would be a mistake to think that the S _floor and the S _ceiling are equal. In the attic, for example, the roof slopes hang overhead, forming a so-called hipped roof. It is immediately noticeable that the quadrature of the floor covering will be larger. Therefore, starting to repair in the under-roof room, the area of each surface is calculated separately.

Calculation of the squared rectangular space

In a standard room, the floor is always equal to the ceiling cover and is calculated by the formula for the rectangle S = AxB.

When plasterboard panels are plastered, wallpapering, plastering, painting of walls and / or ceiling, facing of tiled products and other types of repair works, providing for leveling and finishing of the wall covering, area calculation is required.

All calculations are based on the perimeter and height of the room. Measuring them with a tape measure, substitute in the formula:

S = PxH , where H is the height of the room, P is the perimeter. Formula P = 2 (A + B), where A and B are indicators of the length of adjacent walls.

Do not forget about window and door openings that do not fall under the finish. Their area must be taken away from the total number.

Therefore, before calculating the quadrature of the wallpaper room, all the window openings are measured, after which the area of each is calculated, summed and taken away from the S _room , resulting in a quadrature for the finish.

Important! Remember that for door and arch structures, an additional formula is used for a circle segment or for a semicircle.

How to get the measurement result

How to calculate the square of a room? First measure the walls. To do this, use a regular tape measure. To place a square shape the formula is suitable:

S _rooms = AxB (A is the length, B is the width).

* The width is multiplied by the height, after which a number is obtained reflecting the area of the room in m ² .

Application of the formula in practice

Problems should not arise if you know how to calculate the square of a room. Try to understand the features of calculating the area of the room for wallpapering more details, according to the example.

Often after the completion of the repair work, there are surplus materials. Or at the end of pasting it turned out that the canvas of wallpaper was not enough. Planning the finish, do not forget about the exact and correct calculation of the area of the room. So you will rid yourself of uncomfortable situations in the process of pasting wallpapers.

How to determine how much wallpaper will be required?

Here everything 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 cubature. In dealing with such material, consider its drawing.

The easiest way is to cover the wall with segments with a simple image: the canvases do not have to be adjusted. If you have purchased rolls with complex geometric patterns, prepare that the material consumption will be greater, because the pieces will have to be cut so that the elements of different cuts join together, forming a single whole.

Important! Regardless of the texture and style of the canvas, always add 2-3 centimeters to the allowance under the plinth.

Counting the wallpaper: how to figure it out?

Consider the example. With a perimeter of 12 meters and a standard width of a 53 centimeter roll, 23 stripes of wallpaper are needed to cover the walls.

Important! When overlapping, do not forget to consider the allowances.

If the height of the ceiling in the room is 2.7 m, add at least 5 cm to the allowance. This results in a length of 1 cloth - 2.75 m. With a standard length of material in a roll - 10.05 m, 3 whole strips come out of one package. To calculate the number of rolls, 23 are divided by 3 and the number of packages required for finishing is 7,54, that is, you have to purchase 8 rolls of wallpaper.

Bathroom tiling: how many tiles will be needed

Calculation of the required amount of material is analyzed by an example. Masters use the proven method of calculating the amount of consumables for finishing the bathroom.

To do this, measure the walls and calculate by the formula to calculate the square of the bathroom. Here, as in the calculation of the required number of wallpaper from the total area, door and window openings are subtracted.

Consider the example. So, having received a number of 21 square meters, find the required number of tiles. First, a calculation of the area 1 of the ceramic product is carried out, at a size of 0.3 x 0.2 we obtain 0.06 m ² .

S _bathtub / S _product = n, where n is the number of tiles.

21 / 0,06 = 350 pcs. The stock when stowing products is 10% of the required number. For example, 35 pieces. As a result, it turns out that for facing the bathroom will need 385 whole tile squares.

Important! The amount of floor covering is determined according to the same scheme.

Now you know how to calculate the square of the bathroom under the tile, for wallpapering or for installing floor covering.

Using a simple formula, you can independently determine how much of the finishing material, glue mixture, screed is required to carry out repairs in any of the premises of the house. This is convenient and simple, because there is no need to hire specialists to carry out such a simple job.
