When repairing an apartment or house there is a momentwhen you need to know how much material you need to purchase. In order not to be mistaken with the volume, it is important to know how to calculate the perimeter of the room, its walls, floor and other surfaces.
Calculating the amount of wallpaper
This question arises almost at the very beginningrepair, because you want to buy the right amount of rolls, so as not to suffer a shortage, but also not to overpay for excess. So, you need to know how to calculate the perimeter of the room.
What generally is the perimeter, we all rememberA school course is the sum of the lengths of all sides. If we are talking about a room, then - the walls. So, to calculate the perimeter is required to find out the length of all the walls. It is very easy to do this: it is necessary 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.buy on 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 height of the ceiling is also necessary. Suppose that in this case the room has a standard height of 2.5 meters.
Next, calculate the amount of wallpaper thatrequired to purchase. Today, wallpaper with a width of 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’s not difficult to calculate the right amount of wallpaper.
It is best to show on the sample how to countperimeter of the room. Examples are the best option for most buyers. So, with our size, from one roll of wallpaper will be four bands of material (10: 2.5). These four lanes will occupy four meters from our perimeter, since their width is 1 m. So, to calculate the number of rolls, you need to divide the perimeter by the number of meters covered by one roll of wallpaper: 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 should be rounded up, even if the tenths are few. That is, if it turns out that you need to acquire 5.15 rolls, you need to buy 6. Otherwise, these 15 centimeters will simply have nothing to glue.
Errors
In our calculation, we used the knowledge ofhow to calculate the perimeter of the room, but did not take into account other facts - the presence of doors and windows. Therefore, counting how much wallpaper you need to buy, do not forget to reduce them by the required number of bands.
Floor covering
To purchase flooring is also important to knowhow to calculate the perimeter of the room. The formula is the same: the sum of the lengths of all sides. There is no need to pay attention to the 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.
Рассчитать покрытие для пола, зная периметр и length, it will not be difficult. Often on sites selling these same coverage, there are special calculators. They must enter the length and width of the room, the desired coverage. After that, information will appear about how much material you need to purchase. If we are talking about linoleum, then the variants of its width correspond to the standard end sides of the room. Therefore, buy it, based on the length of the room.
If you buy tile, parquet or laminate,more complex calculations are needed. It is probably best to use the help of managers working in a hardware store or outlet where you will buy coverage.
Ceiling coating
This material is calculated as beforeway. If we are talking about suspended or suspended ceilings, it’s even simpler here - everything will be done by specially trained people who come to the measurements completely free of charge before signing a contract with the company.
As you can see, you should not have any problems with calculations. Good luck!
