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.

Many argue that repair is a process that is almost impossible to complete, it can only be stopped. Despite this, in order not to turn a minor repair into a global one, it is very important to correctly calculate all the necessary numbers and carry out the necessary calculations, one of which is the square measurement types.
Now you know how to find the area of a room, knowing the length and width, and after all the manipulations performed, it’s enough to simply add up the received data by room, then you can to cover the square of the entire apartment.
This process is required for purchasing materials. The last stage will only be the development of a plan, where all the lengths, widths of window and door frames, etc. will be indicated. This is necessary, for example, for laying floor tiles or laminate. This scheme will be required when laying heated floors.
There are also modern applications for smartphones or services on the Internet that will simplify these moments and help you find the area.

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.
Converting other area units
Foreign units of measurement also denote square meter. Only for this purpose they should be converted correctly. This can be done using a simple mathematical calculation:
- Square feet - multiply by 0.093 (exact rate - 0.093903). Measure the length and width in feet and multiply them. Get a square foot. One foot is equal to 0.093 square meters. The result in square feet is multiplied by 0.093 to get a square meter. Example: 13.41 ft x 0.093 = 1.24713 sq. m. Rounding – 1.25 sq. m.
- Yards - multiply by 0.84 (exact course - 0.83613). Everyone does the same thing as when converting from square feet to square meters. Example: 24.7 yard x 0.84 = 20.748 sq. m. Rounding – 20.75 sq. m.
- Acres - multiplied by 4050 (exact rate - 4046.9). We repeat the procedure. Example: 55.3 acres x 4050 = 224014.77 sq. m. Rounding – 224015 sq. m.
Quantitatively, foot or yard values always appear larger than meter values.

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.

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.
Apartment area
Since renovation is a “disaster” that periodically visits us, it is better to make a plan of the entire apartment with detailed measurements. On the same plan, indicate the area of each room. After you calculate the square footage of all the rooms, add up the numbers and get the square footage of the apartment.
For the plan, it is better to calculate the footage of each room
One option could be as in the figure above - in order to know exactly the area of each room. This will be required to purchase materials. But you will also need a plan that will show all the lengths. Partitions, width of windows, doors, etc. This will be required, for example, to develop laying plans for laminate flooring, floor tiles or other coverings. You will also need such a plan when planning a heated floor.
By the way, there is a calculator application for your phone, with which all calculations are very easy to do.
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.
To get the area of a room in the shape of a circle, it’s worth remembering the formula:
S=
