When repairing in an apartment or house, a moment arises when you need to know how much material you need to purchase. In order not to make a mistake with the volume, it is important to know how to calculate the perimeter of a room, its walls, floor and other surfaces.
Calculation of the number of wallpapers
This question arises almost at the very beginning of the repair, because you want to buy the right number of rolls so as not to run out of shortages, but also not to overpay for too much. So, you need to know how to calculate the perimeter of the room.
What is the perimeter in general, everyone remembers from the school course - this is the sum of the lengths of all sides. If we are talking about a room, then about walls. So, to calculate the perimeter, you need to find out the length of all the walls. This is very easy to do: you need to measure two adjacent ones and double the result. For example, if one wall has a length of 4 meters, the other 6, then its perimeter is 20 m: 2x (4 + 6) = 20.
Now you need to calculate how many rolls you need to purchase for such a room. In this situation, it is important not only to know how to calculate the perimeter of the room, but also to understand that knowledge of the ceiling height is also necessary. Suppose that in this case the room has a standard height of 2.5 meters.
Next, calculate the number of wallpapers that you want to purchase. Today, wallpaper, whose width is 1 meter, is becoming increasingly popular. Take for example just such an option. The length of the roll remains standard - 10 meters.
Now, having all the necessary information, it is not at all difficult to calculate the required number of wallpapers.
It is best to show on a sample how to calculate the perimeter of a room. Examples are the best option for most buyers. So, with our sizes, from one roll of wallpaper we get four strips of material (10: 2.5). These four stripes will take four meters from our perimeter, since their width is 1 m. Therefore, to calculate the number of rolls, you need to divide the perimeter by the number of meters that one roll of wallpaper covers: 20/4 = 5. It turns out that we need five rolls of wallpaper.
It is important to know: if the result of the last action is not an integer, it is necessary to round it up, even if there are not enough tenths. That is, if it turns out that you need to purchase 5.15 rolls, you need to buy 6. Otherwise, these 15 centimeters will simply have nothing to seal.
Inaccuracies
In our calculation, we used the knowledge of how to calculate the perimeter of a room, but did not take into account other facts - the presence of a door and a window. Therefore, when calculating how many wallpapers you need to buy, do not forget to reduce them to the required number of stripes.
Floor covering
To purchase flooring, it is also important to know how to calculate the perimeter of a room. The formula is the same: the sum of the lengths of all sides. There is no need to pay attention to doors and windows. It is enough to either measure two adjacent sides and multiply by two, or measure each side of the room and add these numbers.
Calculating the floor covering, knowing the perimeter and length, will not be difficult at all. Often, sites selling these same coatings have special calculators. They need to enter the length and width of the room, the desired coverage. After that, information will appear on how much material you need to purchase. If we are talking about linoleum, then the options for its width correspond to the standard end sides of the room. Therefore, they buy it based on the length of the room.
If you buy tile, parquet or laminate, more complex calculations are needed. Probably, for this it is better to use the help of managers working in a hardware store or outlet where you will buy coverage.
Ceiling coating
I count this material similarly to the previous method. If we are talking about suspended or suspended ceilings, it’s even easier - everything will be done by specially trained people who come to measurements completely free of charge before concluding an agreement with the company.
As you can see, you should not have any special problems with the calculations. Good luck
