Formula: the area of the room and its dimensions

If you plan to make repairs yourself, then you will have to make an estimate for construction and finishing materials. To do this, you will need to calculate the area of the room in which you plan to make repairs. The main assistant in this is a specially developed formula. The area of the room, namely its calculation, will allow you to save a lot of money on building materials and send the released money resources in a more appropriate direction.

Geometric shape of the room

The formula for calculating the area of the room depends on its shape. The most typical for domestic buildings are rectangular and square rooms. However, during the re-planning, the standard form can be distorted. There are rooms:

• Rectangular.
• Square.
• Complex configuration (for example, round).
• With niches and ledges.

Each of them has its own calculation features, but, as a rule, the same formula is used. The area of a room of any shape and size, one way or another, is computable.

Placing a rectangular or square shape

To calculate the area of a room in a rectangular or square shape, it is enough to recall school geometry lessons. Therefore, for you it should not be difficult to determine the area of the room. The calculation formula has the form:

S rooms = A * B, where

A is the length of the room.

B is the width of the room.

To measure these values you will need a regular roulette. To get the most accurate calculations, it is worthwhile to measure the wall on both sides. If the values do not converge, take as a basis the average value of the resulting data. But remember that any calculations have their own inaccuracies, so the material is worth buying with a margin.

A room with a complex configuration

If your room does not fall under the definition of "typical", i.e. Has the form of a circle, a triangle, a polygon, then perhaps for calculations you will need another formula. The area of a room with such a characteristic can be arbitrarily divided into rectangular elements and calculated in the standard way. If you do not have such an option, then use the following methods:

• The formula for finding the area of a circle:

S room = π * R ² , where

Π = 3.14;

R is the radius of the room.

• The formula for finding the area of a triangle:

S room = √ (P (P - A) x (P - B) x (P - C)), where

P is the half-diameter of the triangle.

A, B, C are the lengths of its sides.

Hence P = A + B + C / 2

If in the process of calculation you have difficulties, it is better not to torment yourself and turn to professionals.

Area of a premise with ledges and niches

Often, the walls are decorated with decorative elements in the form of various niches or protrusions. Also, their availability may be due to the need to hide some unaesthetic elements of your room. The presence of protrusions or niches on your wall means that the calculation should be carried out in stages. Those. First, the area of an even section of the wall is located, and then the area of the niche or ledge is added to it.

The area of the wall is according to the formula:

S walls = P x C, where

P is the perimeter

С - height

Also, you need to consider the presence of windows and doors. Their area must be taken away from the resulting value.

A room with a multi-level ceiling

A multi-level ceiling does not complicate calculations as much as it seems at first glance. If it has a simple construction, then calculations can be made by the principle of finding the area of walls complicated by niches and projections.

However, if the design of your ceiling has arc-and wave-like elements, it is more expedient to determine its area with the help of the floor area. For this you need:

1. Find the dimensions of all the straight sections of the walls.
2. Find the floor area.
3. Multiply the length and height of the vertical sections.
4. Summarize the resulting value with the floor area.

Step-by-step instruction for determining the total

Space

In order to correctly calculate the area of your room, you will need not only a certain formula. The area of the room is measured in stages within a strict sequence, which includes the following items:

1. Free the room from unnecessary things. In the process of measuring you will need free access to all parts of your room, so you need to get rid of everything that can hinder it.
2. Visually divide the room into areas of regular and irregular shape. If your room has a strictly square or rectangular shape, then this step can be skipped.
3. Make an arbitrary layout of the room. This drawing is needed to ensure that all data is always at your fingertips. Also, it will not give you the opportunity to get confused in numerous measurements.
4. Measurements must be made several times. This is an important rule to exclude errors in calculations. Also, if you use laser roulette, make sure that the beam lies exactly on the surface of the wall.
5. Find the total area of the room. The formula of the total area of the room is to find the sum of all the areas of individual sections of the room. Those. S total = S walls + S floor + S ceiling
