How to calculate square meters? Probably, there is no more complicated and at the same time simple issue during the repair. Endless calculations, calculations get people crazy. How many families collapsed after starting repairs? It is unknown, but absolutely not without divorces.
There is a very simple way to calculate the wallpaper on the room, or rather their required number. It is necessary to present the walls in the form of a sweep, and even better to draw them. Measure each wall: height and length. It is better to do this more than once and in several places. As you know, in most apartments it is impossible to find at least one right angle. After measuring the wall, you should take the largest numbers obtained for its size. If the wall is a rectangle or almost a rectangle, then the way how to calculate the square meters that make up its area is simple: you need to multiply the length and height of the wall. Adding the area of all the walls in the room, we get the required number of wallpapers. But the calculations are not over yet.
Before calculating the square meters that need to be covered with wallpaper, it should be decided whether the wallpaper panels will be glued butt or lap, when calculating these values will also need to be taken into account. Wallpaper rolls have a specific length and
width, and glued, usually vertically, although options are possible. At the same time, it is not recommended to
glue the wallpaper so that the middle of the panel is at an angle, it is better to stick 2 overlap. In general, the problem is not trivial, at the lessons of geometry for this was not prepared. In addition, you need to take into account that you do not need to glue the door and windows with wallpaper, but the space above and below them - yes. In general, the question of
how to calculate the square meters of the wall is not very relevant, but measurement of the walls still cannot be avoided.
The standard width of the roll of wallpaper is 53 centimeters. Length - 10 meters. Take
for example, a room with walls 5.5 by 8.3 meters, the ceiling width is 2.6 meters. Plus, the space above the door is 60 centimeters, as well as above and below the window - 1 meter. The width of the door takes 1 meter from the smaller walls, and the window 2 meters. That is, the width of the walls remains as follows: 2 walls - 8.3 meters each, 1 wall - 4.5 meters and the last wall - 3.5 meters. And do not forget about the pieces near the door and window.
The ceiling height is 2.6 meters, which means that each roll will produce almost 4 panels, 16 centimeters are not enough, that is, 4 centimeters for each piece of wallpaper. A small detail - the wallpaper does not stick close to the floor and ceiling, it remains
a small gap, so it can be said that from each roll it will turn out 4 pieces from floor to ceiling. On the walls with a length of 8.3 meters, you need 8.3 * 0.53 = 4.4 panels, that is, 4 and a
half, half will have to be at the corners, so you will need to glue the first piece, slightly departing from
angle. On both walls, thus, 9 strips of wallpaper. The 2 most difficult walls remained. Excluding additional pieces on the wall 4.5 meters - 4.5 * 0.53 = 2.4 panels, on the wall 3.5 meters - 3.5 * 0.53 = 1.9. To the whole room - 2.4 + 1.9 + 9 = 13.56, which will be more than 3, but less than 4 rolls. Do not forget about the space above the window and under it, as well as above the door. In general, 4 rolls are definitely enough, and there should not be much left.
Calculating the cost of repairs in such a way as to do everything qualitatively, but not to breach the budget, is the greatest art. But also cases when the wallpaper is missing a little bit are also not uncommon, so all calculations need to be done very carefully.
