A square meter is the basic unit of measurement, without which you will not buy the right amount of paint to paint the walls, build a house or tiling. When buying building materials, you should also remember to buy them with a 10% -15% stock, even if the calculations are correct. Moreover, e.g. in the case of calculating the roof area, the steel roofing tile has a specific covering efficiency: e.g. 1 m2 of the roof may contain more material than we think, because the elements are placed overlapping.

No house, roof, walls or floor is a perfect, simple solid or figure that you can count according to the ready formula for counting square meters. Calculating square meters can be difficult if you are dealing with slopes, curves, slopes, or even windows in the wall. The number of square meters of plaster, polystyrene or metal tiles leaves no less doubt. How to count square meters of a troublesome area?

How to calculate the m2 of a room

How to calculate the area of ​​a room with windows, balcony or slants? In theory, the rule is simple: Just multiply the width by the length to get the dimensions in square meters.

They can count the wall areas and only subtract doors and large openings, and leave windows (plastering is a lot of work on door frames and frames, so many contractors include them). The issue of bevels and unevenness when counting interior plasters (usually the price per square meter is included in the service) is agreed individually, in any case, do not stick to your own rigid calculations - treat them as a starting result for negotiations.
