Proper repair work depends on the correct calculation of square meters. After all, the purchase of all building materials is the first stage of any repair. Without these data, it is impossible to buy building materials necessary for repair. In order not to waste your savings and prevent a shortage of finishing materials, you need to know exactly how to calculate the square meters of the room.
Why you need to calculate the quadrature
There are different situations in which it is simply necessary to know the exact parameters of the room. Most often, such data is needed to carry out repairs, obtain a cadastral passport, or to sell a room. If an error occurred during the calculation, this leads to undesirable and additional costs. To avoid unpleasant consequences, you need to know exactly how to calculate square meters correctly.
The amount of housing tax depends on accurately calculated data. The amount of tax depends on the number of square meters of surface area. Selling the premises, the owners must measure it before deciding on the price.
As for repair work, accurate measurements of the quadrature make it possible to determine the required amount of building materials and the cost of finishing work.
The amount of wallpaper and paint depends on how square meters of the walls are calculated, and whether it is done correctly.
How to calculate square meters of wall
It is necessary to calculate the quadrature of the wall, since without these data it is impossible to determine the general parameters of the room. Taking a tape measure, a notebook and a calculator begin to measure the wall. First of all, the width of the wall and its height from the ceiling to the floor are measured. Often the rooms have uneven angles, and this affects the process of measuring quadrature and the source data.
The total result and the number of required building materials depend on how square meters of the wall are calculated. After measurements, the length and height of the wall are multiplied, for example: wall parameters: length - 3.8 m, height - 2.8 m. Thus, the total indicator is: 3.8 x 2.8 = 10.64 m 2 .
Calculations by this principle are done for each wall separately. When all measurements are made, the results need to be combined. If the walls are uneven, you need to measure them on each side, and then calculate the arithmetic average and multiply it by two.
Calculation of square meters
How to calculate the square meters of a room? The layout of the room is not always rectangular, there are also non-standard solutions. There are many diverse and unusual options, so you need to familiarize yourself with them so that in the future there are no problems with calculating square meters.
If the room is connected to the balcony, it is necessary to calculate the area resulting from the redevelopment of the room. To determine the total quadrature, it is worth doing the following:
- We measure a room without a balcony. For example, the length of a large room is 6 meters and the width is 7.8 meters.
- The measurements obtained must be multiplied: 6 x 7.8 = 46.8 m 2 .
- Next, you need to measure the balcony. Let's say the loggia is 3.2 m long and 2.5 m wide.
- The results need to be multiplied: 3.2 x 2.5 = 8 m 2 .
- All results must be added: 46.8 + 8 = 54.8 m 2 .
Thus, we get a common indicator of two connected rooms. If in the process of redevelopment the room is connected to a corridor or storage room, then the resulting measurements are also added to the overall indicator. Thanks to these calculation examples, you can easily find out how to calculate square meters correctly.
Wall area excluding windows and doorways
When measuring a room, a person who does not know all the nuances often encounters problems. Particular difficulties arise during the calculation of the squaring of a wall with windows and doorways.
If there are two windows in the wall, then you need to know how to calculate the area of the wall in square meters, excluding window openings.
It is necessary to multiply the width and height of the wall: 3.5 x 5.5 = 19.25 m 2 .
After the general indicator is found, we measure the window opening and calculate its area. For example, the height and width of the window frame is 0.8 meters by 1.4 meters.
Multiplying the indicators, it turns out that the window area is 1.12 m 2 .
Since there are two windows, 1.12 m 2 must be multiplied by two, and in the end we get 2.24 m 2 .
Then, from the total square of the wall, we subtract the area of both windows: 19.25 - 2.24 = 17.01 m 2 .
In the same way, the area of doorways located on the wall of radiators, fireplaces and other elements is excluded.
How to calculate the area in an room with irregularly shaped walls
Many people ask how to calculate how many square meters is the area of a curved room. An easy way to find out the quadrature of a room is to plan the room and divide the complex shapes into lighter ones.
The area of the room with beveled corners is found by the formula S = ab / 2.
This formula allows you to find the area of the triangle and subtract it from the total square of the room. The vertical sides of the triangle are indicated by the letters a and b. The slanted side does not need to be calculated.
To find out side a, it is necessary to measure the width of the wall from the beginning of the cut, then the opposite, and then calculate the difference between them. For example, the beveled side is 1.3 meters, and the opposite side is 3 meters, which means that side a will be 1.7 meters.
Side b is defined in the same way. To calculate, you need to compare the length of the room. For example, 6 meters and 3.4 meters, the difference between them will be 2.6 meters. Then we multiply all the results and divide them into two, in the end we get 2.21 m 2 - the area of the cut triangle. Thus, knowing how to calculate the square meters of the floor in a curved room, you can easily find the necessary indicators.
How to calculate the number of tiles
When making repairs in the bathroom or in the kitchen, you need to know how to calculate the square meter of tiles for surface finishing. Even the smallest errors in the calculations can provoke a halt in the workflow. As a result, you will have to buy the missing materials and spend a lot of time looking for identical tiles.
If the tile is needed for finishing the floor, then it is worth figuring out how to calculate the square meters of the floor correctly. In addition to the size of the room itself, you must know the size of the tile. For example, a square tile has sides of 0.33 meters, and a bathroom of 170 by 175 centimeters. To calculate the required number of tiles, you need to multiply the length and width of the bath, and then multiply the sides of the tile. The resulting floor area is divided by the area of the tile. The result is the exact amount of finishing material. When buying tiles, you always need to take a few pieces in reserve.
Area Tools
Before calculating square meters, decide on the tools used to calculate the area. To calculate cubic meters, two methods are used:
- Online editor. This is a special program that must be downloaded to your phone or tablet. The editor program allows you to obtain the necessary data and highlight individual fragments using a diagram drawn by the size of the room room. The advantage of this method is a quick and accurate calculation, even in rooms with the wrong layout. The minus of the program is a long study of the interface and features, the mandatory presence of a gadget.
- Manual parameter counting. Writing all the data you just need on a piece of paper with an ordinary pencil. This method requires special vigilance, since it is easy to make mistakes during calculations.
Some recommendations
If it is not possible to find out the floor area from the house book, you need to know exactly how to calculate square meters in another way. During the calculations, you will need good knowledge of geometric formulas and the skills of using a calculator online.
It is best to divide a room with an incorrect layout into separate figures or apply the formula for the radius of the circle, resulting in the necessary value.
It is not difficult to calculate the quadrature of the room, you just need to remember the school curriculum. But also do not forget that the resulting calculations must be properly rounded so as not to leave excess building materials and not to run to the store for missing items.
Use the examples and formulas given and calculating the area of a room or apartment will be an easily solved task for you. So you will find the answer to the question of how to count square meters of floor, walls and ceiling.
