Square meter is: how to calculate the area of a room

A square meter is a generally accepted unit of measurement of area and size of objects. It simplifies the calculation of the area of premises, land plots, and the consumption of materials during repairs and construction.

Calculating square meters is not difficult. The main thing is to take measurements correctly and be able to use a simple calculation formula.

Areas of application

The area of a square with a side length of one meter is equal to a meter squared.

The Russian designation for a square meter is m², in the international system it is m². Used in the international systems of units SI, MTS, MKGSS.

The square meter as the basic unit of measurement is used in the following areas:

construction and repair;
interior design;
sale/purchase of real estate;
purchase/sale/rent of land plots.

In addition, it is found in the school curriculum in mathematics and physics.

Quadrature calculation is needed in the following cases:

find out how much corrugated sheeting is needed to cover a garage or fence;
determine the total consumption of building materials during the construction of a house, bathhouse or other building;
calculate the number of paving slabs for flooring in the local area, alley;
calculate the amount of wallpaper to decorate a room or an entire apartment;
to simplify the determination of the consumption of roofing materials for roof decking;
to understand how much plaster or putty will be needed for certain jobs.

The list is far from complete, since in the construction industry, many materials are usually measured in square meters.

It is also permissible to calculate the area of land that is in use in square meters. Sometimes you can find measurements in hundreds, acres. For large areas of land, it is more convenient to use square kilometers or hectares.

Legislative basis

All issues that relate to residential premises in apartment buildings are regulated by the Housing Code of the Russian Federation.

Also, if the need arises, you can refer to such regulatory documents as:

Construction norms and rules (SNiP) from 2003.
Federal Law No. 384 of December 30, 2009, which presents technical regulations for the safety of buildings and structures.

Important: The priority of regulation among these documents belongs to the latter (Federal Law No. 384). Thus, its provisions may cancel the effect of some clauses of the RF Housing Code and SNiP 2003.

When studying the Housing Code in order to calculate the square footage of an apartment, it is especially necessary to highlight Article 15, which provides a definition of what exactly is the object of housing rights.

Formula for calculating square meters

Correctly calculating the quadrature of most objects that have the shape of a rectangle can be done using the following formula:

S=P*h, where

S – area of the required object, surface (in sq. m);
P – perimeter;
h – height.

The perimeter should be calculated using the following formula:

P=(a+b)*2, where

a – length;
b – width.

If we are talking about the area of the premises, then the height should be measured at the vertical angle, the length and width should be measured with a tape measure along the baseboard.

Calculation rules

As you already understand, living space is considered the main indicator influencing the value of real estate. Let's try to figure out how it is calculated. This point is very important. A component of this space is the room in which you can live. Therefore, to calculate the living area of a room, it is enough to simply add together the footage of all the rooms. The result should be the required indicator. To calculate the area of a room, you should use simple mathematical formulas. Measurements are taken on the inside of the baseboard.

How to calculate the area of various rooms and their elements

Depending on the shape and purpose of the premises, the calculation procedure may differ.

Rooms, kitchens and apartments

You can correctly calculate the area of a room based on its size. You can measure the length and width with a regular tape measure.

For example, the area of a 3 by 3 kitchen is 9 square meters. m, since the length and width of the room are 3 m. We simply multiply these numbers together. The area of a 3 by 4 room will be 12 square meters. m, kitchens 3 by 6 - 18 sq. m.

These examples are only suitable for regularly shaped rooms that do not have protrusions or chamfered corners.

Paula

You can calculate the total square meters of the floor based on the geometric shape of the room. If the floor is square or rectangular, then you need to measure the length and width, and then multiply the results obtained by each other.

Calculating the floor area without taking into account the stove or fireplace installed there may be necessary when calculating the consumption of floor tiles, laminate or other flooring material.

It is necessary to count in the following order:

The first step is to find the total floor area.
Then calculate separately the area of the furnace area.
To get the final result, the area that the stove will occupy is subtracted from the total floor area.

The same should be done when other elements (windows, doors) need to be excluded from the total area of the room.

If the floor has a complex, multifaceted shape, then it should be divided into simpler shapes and the area of each of them should be found, and the results should simply be summed up.

Walls

The area of the walls, be it a living room, bedroom or kitchen, must also be determined based on the shape and the presence of additional elements.

To obtain the square footage of the walls, the perimeter of the room is multiplied by its height. The area of windows and doors is subtracted from the result obtained.

In the form of a formula it looks like this: S walls=P*H – S doors – S windows

Such calculations are useful for determining the amount of brick for building a house or material (wallpaper, drywall) for finishing rooms.

Ceiling

The area of a regular ceiling will be calculated similarly to the floor. If there are additional elements on the ceiling (chimney pipe) or it has a multi-level structure, then it is divided into simpler shapes. The areas of simple figures are summed together.

Land plot

The area of the land plot is calculated similarly to the previous options. Width and length measurements are taken. After which the resulting numbers are multiplied among themselves. For example, if the length of the plot is ten meters and the width is six meters, then the area will be sixty square meters.

It is often customary to calculate the area of land in acres. It is important to remember that 1 hundred square meters is equal to 100 square meters. m. Also in economics there is the concept of a hectare, where 1 hectare is equal to 100 acres.

For large areas of land, a square kilometer is used, which is equal to 1,000,000 square meters. m.

Room volume

The cubic capacity of a room, or volume in construction, is used when calculating the required heating, ventilation, and air conditioning power of a room.
Volume is measured in cubic meters. The unit is written as 1 m³.

From a geometric point of view, the room as a figure is a hexagon .

By measuring the length, width and height of a rectangular room, multiplying the resulting measurements, you get the volume of a simple room .

The volume of a complex-shaped room is calculated as follows:

the floor of the room is divided into simple geometric shapes;
calculate the quadrature of each figure;
the resulting values are added and multiplied by the height to the ceiling.

How to calculate the square footage of an irregularly shaped room

In apartments and private houses, rooms are not always made in the correct square and rectangle shape. There are no restrictions in design, so there are rooms in the shape of a circle, triangle, polyhedron and combined shapes.

To find out the area of a room of a non-standard shape, divide it in the drawing into simpler shapes and find the area of each of the shapes. The results are summarized.
