In order to determine the cost of services for wallpapering by a private master, you need to know the total area of \u200b\u200bthe walls and the perimeter of the room. There are services that are calculated by square meters, such as gluing or priming. And there are services for which you need to know the running meters, for example, installation of skirting boards or gluing curbs. It is not necessary to use the services of measurers, just remember the school curriculum in geometry. This information will also help in calculating the required amount of wallpaper, glue, and so on.
Wall area = room perimeter * ceiling height
First you need to measure the width and length of the room. We must say right away that the obtained measurements of the length and width of the room must be converted into meters. For example, if the length of the room is 325 centimeters, then we consider 3.25 meters.
Room length 4.75 meters
Room width 3.25 meters
Calculate the perimeter of the room, which is equal to the sum of all sides.
P \u003d (a + b) x2, where a and b are the width and length of the room. Therefore (4.75 + 3.25) x2 = 16 meters.
The perimeter of our room is 16 meters. P=16 meters.
Now you need to measure the height of the room. We measure the height of the wall - we got 2.71 meters.
h=2.71 meters.
To get the area of the walls, you need to multiply the perimeter of the room by the height of the walls.
S walls \u003d Pxh, where h is the height of the walls.
S walls \u003d 16x2.71 \u003d 43.36 meters.
The area of the walls of our room is 43.36 square meters. meters. S=43.36 m2.
From this figure, you need to subtract the area of \u200b\u200bwindows and doors - after all, there is no need to glue wallpaper there. We have one window in the room, the area of \u200b\u200bwhich is 1.95 m 2 (1.3m x 1.5m). Door area 1.17 m 2 (0.61m x 1.92m). The sum of the areas of windows and doors that are not involved in wallpapering is 3.12 m 2.
The net area of the walls is 43.36 - 3.12 \u003d 40.24 m 2.
In cases where the room is of a non-standard size and does not look like a rectangle, you will have to calculate the area of \u200b\u200beach wall separately and then sum them up.
Table of wall areas for wallpaper and painting
Below is a table that will help you quickly determine the area of \u200b\u200bwalls for wallpapering (or painting). To calculate the indicators, the typical area of windows and doors was used. Wall area indicators vary according to the height of the ceiling of the room:
| Room area, m 2 | Room ceiling height 2.50 m | Room ceiling height 2.70 m | Room ceiling height 3.0 m |
| 10 | 29 | 31 | 33 |
| 11 | 30,5 | 32,5 | 34,5 |
| 12 | 32 | 34 | 36 |
| 13 | 33,5 | 35,5 | 37,5 |
| 14 | 35 | 37 | 39 |
| 15 | 36,5 | 38,5 | 40,5 |
| 16 | 38 | 40 | 42 |
| 17 | 39,5 | 41,5 | 43,5 |
| 18 | 41 | 43 | 45 |
| 19 | 42,5 | 44,5 | 46,5 |
| 20 | 44 | 46 | 48 |
| 21 | 45,5 | 47,5 | 49,5 |
| 22 | 47 | 49 | 51 |
| 23 | 48,5 | 50,5 | 52,5 |
When carrying out repairs, the question arises:how much is a square meteryou need materials to cover it.
In order not to spend extra money, it is better to start by makingcalculation of square metersrooms and only then go to the store with specific requirements.
On packages with paints, plaster, primer, it is necessarily indicated for what size of the room this amount of the mixture is calculated.
The main question is how many packages or cans are needed to cover the wall or floor area.
What is a square meter
First you need to decide what a square meter is. People who did not learn mathematics well at school still face the problem of counting the amount of building materials sooner or later. Sosquare meter - the main reference point in determining the area of \u200b\u200bthe room.
If you draw a square (this is a geometric figure with the same sides), and the side is equal to 100 cm, then when multiplied by 100 we get the number 10,000 cm. This means that the size of this figure is 10,000 cm2. It can be easier. Calculate in meters: 100 cm is 1 m. We apply the formula for calculating the area - we multiply the two sides, that is, we multiply 1 by 1, we get 1 m. So, the size of the square is 1 sq.m.
Square Meter Counting Tools
For calculations, you need to prepare a calculator.
If it is not there, then the multiplication table on a regular notebook for a first grader.
If the walls are not 2, not 3 meters, but, for example, 2.5 meters, then a calculator is still better. This is too much work for a brain that is not used to working with numbers.
It is advisable to have a piece of paper and a pen handy for writing.
You need to measure with a tape measure or centimeter.

Formula for calculating square meters
To calculate the area, you need to applysquare meter formulaA X B, where the number A is the length of one side, and the number B is the length of the second side. They can be the same if the shape of the floor or wall is square.
Most often, it is not square, but rectangular, that is, the number A will have one value, and the number B will have another. They will need to be multiplied in the mind, or according to the multiplication table, or on a calculator. And the resulting number will be the area that will need to be covered with paint or something else.
It happens that the shape of the floor is not standard, but, for example, trapezoidal. Then it is more difficult, especially for those people who do not know what a triangle is (this also exists in nature). To calculate the size of a trapezoid, you must first calculate the area of the rectangle in the middle, then the size of each triangle on the sides , then add these three numbers. Isn't it easier to call a team of workers right away? let them thinkhow to calculate the square meters of a room.
Important!If at this stage there is a misunderstanding, then it is better to immediately call the teacher of mathematics and ask to calculate,how many sq. meters has a room.

Floor or ceiling area
The ceiling and floor in an ordinary apartment are the same.How to calculate square meters?Very simple. If the room is attic, then there is no ceiling - there is only a floor and walls.
Stage number 1. Measure the length of the room and write down the resulting number on paper. If the number is an integer, then just write the number. For example, 5 (m). If the number is greater than 5, but less than 6, then you will have to remember the decimal fractions and write, for example, 5.5 (m).
Stage number 2. Measure the width of the room and record in the same way. For example - 3m.
Stage number 3. Now you need to multiply these two numbers. Example: 5 x 3 = 15m. So, the floor area is 15 square meters. m. Therefore, the size of the ceiling will also be 15 square meters. m. Write this number separately and circle it with a pen.
solid wall area
How to calculate quadraturesolid wall? Just like we measured the floor or ceiling. The algorithm of actions is the same as when calculating the size of the floor:
- measure the length of the wall and record;
- measure height;
- multiply two numbers - the result will bearea in square meters.
Example: height 2.20 m, length 7 m. 7 x 2.2 \u003d 15.4 m. Wall area - 15.4 square meters. m.
How to calculate the square meters of a wall with a window
It will be more difficult to deal with the wall on which the window is located.
Action algorithm:
- According to the scenario already passed, calculate the size of the wall. Let there be an already known number - 15.4 m2.
- Next, measure the height and length of the window. Multiply numbers. For example: length 1.5 m, height 1.2 m. If you multiply, you get 1.8. So, the area of the window is 1.8 square meters. m.
- We take the area of \u200b\u200bthe wall and subtract the size of the window from it: 15.4 - 1.8 \u003d 13.6. The area that will need to be put in order is 13.6 square meters. m.
Important!The numbers that are obtained during the calculations must be written down and circled with a pen so as not to get lost in your own calculations.
How to calculate the square meters of a wall with a door
Similar actions should be taken when requiredcalculate square meterswalls with a door. If the door is mathematically a simple rectangle, then we calculate its area using the usual formula A X B. That is, you need to measure the height and length, then multiply the numbers and get the size of the door.
Next, subtract the size of the door from the wall area and get the quadrature for which it will be necessary to buy finishing materials. If the previous owner of the apartment made a door with an arch, then here you can’t do without calculating the size of the circle.
Measuring the area of complex shapes
Circle and triangle - complex figures for self-calculation. How to measure square meters of a circle if there is no mathematical or engineering education? Again, formula.
How to measure the size of a circle
There is a formula for calculating the area of a circle. There is such a constant number - the ratio of the circumference of a circle to its diameter. It is the same for all circle sizes. It is called pi and equals 3.14. This is the number that is used in the calculations.
Stage number 1. We measure the diameter (this is the line that runs through the center of the circle from one edge of the circle to the other). Let the diameter be 3 m. Next, we find the radius - this is half the length of the diameter. That is, 1.5 m. We write down the radius on paper.
Stage number 2. We make calculations according to the formula S \u003d PR2, where S is the area of \u200b\u200bthe circle, P is a constant number, and R is the radius of the circle. It turns out 3.14 x (1.5 x 1.5) \u003d 7.065. The area of \u200b\u200bthis circle is 7.065 square meters. m.
But this is the area of a whole circle. The arch above the door is half a circle. This means that you still need to divide this number by two and then add it to the rectangular area of \u200b\u200bthe door. 7.065: 2 = 3.53 m2.
How to measure the area of a triangle
If the previous owner of the apartment was a mathematician, then he could well have made triangular figures on the ceiling, which have to be restored and highlighted with a different color or plaster. You have to consider not to overpay.
Calculation of a square meterin a triangular figure begins with a careful examination of this figure.
It is necessary to find the base of the triangle, that is, the line on which the other two rest (like a roof on a house). Next, draw a line from the opposite top to the base. Write down these two numbers.
Stage number 1. Divide the base of the triangle by 2 and write it down. This number will come in handy in the near future. Measure the height and write it down too.
Stage number 2. Produce calculation m2 figures. To do this, use the formula: S \u003d 0.5ah, where S is the area of \u200b\u200bthe triangle, a is the base, and h is the height. Example: base 3 m, height 2.5 m. Total: 0.5 x 3 x 2.5 = 3.75. The size of the triangle is 3.75 m2. Write it down so you don't forget.
Advice!When calculating, it is better to invite another person to help. One head is good, but two is more reliable.
The point is small - go to the store and buy materials. Here you still have to consider, since not all packages are designed for large rooms. For example, the size of the ceiling in the kitchen3 x 3. How many square metersplaster will be needed if one package can cover 3 square meters. m? We consider: the size of the ceiling is 9 square meters. m. One package goes to 3 square meters. m. Therefore, 3 packs are needed for the entire ceiling.
If it is written on the package that the cost of12 square meters, that means how muchmaterial is needed to cover a wall measuring 3 x 4 m.
Or another example. wall in the apartment6 by 4. How many square metersneeds to be painted? Multiply 6 by 4, we get24 square meters. How much is thisyou need cans of paint of 3 liters, if each can is spent on 6 square meters. m? We consider: 24 divided by 6. It turns out 4. So, you need to buy 4 three-liter cans of paint to cover the entire wall.
For repair work, it is always better to take a little more materials so that you do not have to go to the store again.In the future, if you have to tint or whiten something, the leftover materials can help out a lot.
You can do it even easier and simply multiply all sides of the room: ceiling, floor, walls.
Converting square centimeters to square meters
Before you find out how many square meters are in a room, it is very important to understand the values themselves, because when there is a calculation with hundreds of centimeters, they must be converted to meters in any case. This is done according to the following formula, already using a well-known example: 160 cm * 100 cm - the difference in values (in one meter - 100 centimeters), as a result, 16000 cm2 is obtained, which must be divided by 10000 and we get = 1.60 m2.
These numbers are much easier to operate and remember. Moreover, the "squaring" of the room is always measured in meters. To translate, you need to substitute the following formulas:
- 8000 cm² / 10000 = 0.8 m²;
- 34000 cm² / 10000 = 3.4 m²;
- 2400 cm² / 10000 = 0.24 m².
Everything is quite simple and it will not be difficult to make such simple arithmetic calculations, even for a schoolboy. It is very important before you know the quadrature of the room, to take the most accurate measurements, and then proceed to the calculations.
How to calculate the area of a room in square meters
The need to calculate the area often arises only during repair work, construction or when changing furniture. Almost all building materials (such as flooring) are calculated in square meters. For the correct calculation of the amount of material, it is important to know the floor area. Knowing the width and length of the room, finding the area will not cause any difficulties.
measurements
Before measuring a room in square meters, a minimum set of items is required:
- calculator;
- roulette;
- pencil;
- paper.
On paper, you need to make a detailed plan of the room. Each wall must be measured using a tape measure.
Attention! It is very important to take measurements at floor level, because there are cases (especially in older houses) when the walls are a little littered to one side. Since the floor is measured, it is necessary to measure with a maximum fit to the walls.
The second stage is putting down the obtained measurements on the plan. It is best to immediately do this in meters, but the accuracy of each measurement should be up to 1 centimeter. This is necessary so that when choosing the required amount of materials, it is possible to select the footage of the required material as accurately as possible. Rolled floor coverings are sold in running meters.
Rounding is possible only in case of a small increase, so that in case of unforeseen circumstances, there is a sufficient amount of material.
How to calculate the square of a room
To understand how to find out the total area of \u200b\u200bthe room, you need to use a simple formula and multiply the length readings by the width. As shown in the figure, the long wall has a length of 7 meters and the opposite is only 4. It turns out that the floor area will be 28 m2. This is how the quadrature is found. It is imperative to remember about the small margin that will be required for fitting and trimming, and the more difficult the styling option is, the more stock will be required.
Often, rooms do not have an even square or rectangular shape. Therefore, before finding out the area of \u200b\u200bthe room in square meters, you just need to break the room into several simple shapes (squares and rectangles) and then calculate the total square. So for example, for a room that has the shape of the letter G, it is enough to break it into 2 rectangles, separately calculate the area, and then add it up.
It all looks like this:
- we calculate the quadrature of a large rectangle: we multiply 5 by 4.35 and we get 21.75 square meters;
- now, according to the same principle, the second: 2.5 by 2.65 and we get 6.625 squares;
- then we sum up the total result of 6.625 + 21.75 and get the area of the room in the amount of 28.375 square meters.
Having the exact result in hand, you can round it up a little and take into account 28.4 square meters.
In the event that the room has a section with a cut wall, as shown in the picture, then you need to draw a rectangle so that the oblique divides it into 2 triangles. Then again the room is obtained in the shape of the letter G. Next, you can calculate the area using the method presented above.
You will need to find the area of three rectangles. The missing area is half a small rectangle. It will be enough just to find its area and divide by 2, then add to the rest of the dimensions.
So, for example, you can use the following data:
- large rectangle: 1.75 m * 1.93 m = 3.3775 m². To make it easier, let's take 3.38 m²;
- middle rectangle: 1.18 m * 0.57 m = 0.6726 m². Again, we will round up to 0.67 m²;
- smallest rectangle: 0.57 m * 0.57 m = 0.3249 m2, adjusted to 0.33 m2;
- now it remains only to add the resulting values \u200b\u200band add ½ of a small rectangle: 3.38 + 0.67 + 0.33 / 2 \u003d 3.38 + 0.67 + 0.17 \u003d 4.22 m².
This is the most convenient technique that anyone can use. It is enough to break a complex figure into several simple ones. Despite the fact that there will be more measurements, this method does not require much effort and time losses, and all calculations can be done literally on the knee.
Apartment area
Many argue that repair is a process that is almost impossible to complete, it can only be suspended. 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 measuring the quadrature.
Now you know how to find the area of \u200b\u200bthe room knowing the length and width, and after all the manipulations performed, just add the data obtained by the rooms, then you can get the square of the entire apartment.
This process is required for purchasing materials. The last step will only be the development of a plan, where all lengths, widths of window and door frames, etc. will be indicated. This is necessary, for example, for laying floor tiles or laminate. Such a scheme will be required when laying a warm floor.
There are also modern applications on a smartphone or services on the Internet that will simplify these moments and help you find the area.
Why you need to know the floor area
Determining the area of a rectangular room
Calculation of the area of the room of the wrong layout
Finding the area of a triangular room
How to calculate the area of the walls of a room
Proportions between floor and window area
It is impossible to repair the floor surface without knowing the exact floor area in a private household or apartment. The fact is that today the cost of building materials is quite high, and every property owner tries to save as much as possible on their purchase. Therefore, information on how to calculate the floor area will not be superfluous for someone who prefers to make repairs with his own hands.
Before starting work, you should decide on the scope of activities, plan costs and calculate the amount of building materials. To do this, you will need the original data. For this reason, it is important to know how to calculate the floor area accurately. This is especially true for uneven surfaces and rooms with a non-standard layout.
There are other reasons when there is a need to accurately determine the dimensions of the floor surface:
- checking the quality of construction work;
- the need for redevelopment of the premises.
Determining the area of a rectangular room
Before you calculate the floor area, you should stock up on a calculator and a measuring tape. Most often there are rooms in the shape of a rectangle. To calculate their area, they use a formula known to everyone from school: S \u003d a x b, where a and b are the length and width. For example, a room has parameters of 3 and 4 meters, then the desired value will be 12 square meters. m.
In the event that the room has a fireplace or built-in furniture, then you need to find out their area and subtract from the total area. In the case of a major overhaul of the floor, all unnecessary in the room will have to be dismantled.
Calculation of the area of the room of the wrong layout
It is much more difficult to calculate the area of a room that has a polygonal shape. Often in brick houses in the layout there are niches, triangular recesses and rounded elements, as in the photo.
In this case, before calculating the quadrature of the floor, the layout of the room must be divided into separate zones. For example, if the room has an L-shaped layout, it should be divided into 2 rectangles, then calculate the area of \u200b\u200beach of them and add the results.
Finding the area of a triangular room
When another part of the room is not perpendicular to the main area, this means that there is also a triangle between the two rectangles, which has a right angle.
In this case, the area of the triangle is calculated by the formula: S \u003d (a x b): 2 and added to the grand total. For example, a \u003d 2, b \u003d 3, then S \u003d (2x3): 2 \u003d 3 m².
You can define the area in another way:
- First calculate the square of the rectangle.
- Determine the area of the beveled triangular corner.
- Subtract the area of the triangle from the quadrature of the rectangle.
In the case when the triangle does not have a right angle, then use the Heron formula S \u003d √p (p - a) (p - b) (p - c).
For example, its sides are 5, 6 and 7 meters, then the calculations are made as follows:
- Find out the semiperimeter of the triangle p = (5+6+7):2 = 9.
- Digital values are substituted into the Heron formula and the result is obtained: √ (9 x (9-7) x (9-6) x (9-5) \u003d 14.7 m².
The square of the premises is rounded
Often, a similar form is present at the windows in old houses or on balconies that are combined with rooms. First, calculate 1/2 of the protruding part of the circle and add to the area of the rectangle, applying the formula S = πR²: 2, in which:
R² is the radius of the circle squared.
For example, the room has a protruding semi-circular balcony with a radius of 1.5 meters. Substituting this number into the formula, we get the result: S \u003d 3.14x (1.5)²: 2 \u003d 3.5 m². See also: "How to calculate the square meters of the floor with different shapes of rooms."
How to calculate the area of the walls of a room
The procedure for calculating the area of \u200b\u200bwalls and floor is different. The fact is that before you calculate the quadrature of the floor, you should find out the length and width of the room, and to calculate the walls you will need to measure its height. Therefore, they first find out the perimeter of the room and multiply by the height of the ceilings.
For example, the floor parameters are 3 and 4 meters, and the height of the room is 3 meters. In this case, the perimeter of the walls will be equal to (3 + 4) x2 = 14 m, and their area S = 14x3 = 42 m².
In this case, one should not forget about the quadrature of the openings of windows and doors. Their area is subtracted after the completion of wall calculations. But on the other hand, they can be ignored and thus provide a certain supply of materials.
Proportions between floor and window area
According to SNiP 31-01-2003, the parameters of windows and their number should depend on the quadrature of the floor. So for residential multi-apartment buildings, the ratio between the areas of window openings and the floor surface will be from 1:5.5 to 1:8. As for the upper floors, a minimum proportion of 1:10 is allowed there.
For private households, this norm is regulated by SNiP 31-02-2001. According to this documentation, for every 8 "squares" of the floor surface, there must be at least one "square" of a source of natural light flux. On the attic floors, this proportion cannot be less than 1:10.
To ensure high-quality repairs, you need to find out in advance how to calculate the floor area and other necessary dimensions of the room. The preparatory stage also provides for the purchase of building materials and then during the repair process, costs will be minimized, since there will not be large residues and the cost of delivery will be inexpensive.
The manual method of calculating how to find out the floor area will take longer than when making calculations on an existing building calculator, but it allows you to find out more accurate results.
Web Tools

The name "hectares" is formed by adding the prefix "hecto ..." to the name of the area unit "ar":
1 ha = 100 are = 100 m x 100 m = 10,000 m2
a unit of area in the metric system of measures, equal to the area of a square with a side of 10 m, that is:
- 1 ar \u003d 10 m x 10 m \u003d 100 m2.
- 1 tithe = 1.09254 ha.
land measure used in a number of countries using the English system of measures (Great Britain, USA, Canada, Australia, etc.).
1 acre = 4840 sq. yards = 4046.86 m2
The most commonly used land measure in practice is hectare - the abbreviation ha:
1 ha = 100 are = 10,000 m2
In Russia, a hectare is the main unit for measuring land area, especially agricultural land.
On the territory of Russia, the unit "hectare" was put into practice after the October Revolution, instead of the tithe.
Old Russian units of area measurement

The area of land plots for individual housing construction, private household plots is usually indicated in acres
One hundred- this is the area of \u200b\u200ba plot measuring 10 x 10 meters, which is 100 square meters, and therefore is called a hundred.
Here are some typical examples of the sizes that a land plot of 15 acres can have:
In the future, if you suddenly forget how to find the area of a rectangular plot of land, then remember a very old joke when a grandfather asks a fifth grader how to find Lenin Square, and he answers: “You need to multiply the width of Lenin by the length of Lenin")))
It is useful to know this
- For those who are interested in the possibility of increasing the area of land plots for individual housing construction, private household plots, gardening, horticulture, which are owned, it is useful to familiarize yourself with the procedure for registering cuts.
- From January 1, 2018, the exact boundaries of the site must be recorded in the cadastral passport, since it will simply be impossible to buy, sell, mortgage or donate land without an accurate description of the boundaries.
This is regulated by amendments to the Land Code. A total revision of the borders at the initiative of the municipalities began on June 1, 2015.
- On March 1, 2015, the new Federal Law “On Amendments to the Land Code of the Russian Federation and Certain Legislative Acts of the Russian Federation” (N 171-FZ “dated June 23, 2014) came into force, in accordance with which, in particular, the procedure for buying land plots from municipalities was simplified. with the main provisions of the law can be found here.
- With regard to the registration of houses, baths, garages and other buildings on land owned by citizens, the situation will improve with a new dacha amnesty.
Area search
In preparation for the renovation of a house or cottage, he must correctly calculate the size of the space, which is important when buying materials, but in fact for most repairs. It will not be a mistake in the amount of materials needed (tiles, wallpaper, etc.).
To determine the size of an aircraft, a special square calculator is useful on the Internet, which helps to find the size in square meters. With this, you can get the job done quickly and quickly.
The question of "how to calculate the area of a room" causes many owners of apartments and houses that have a square meter area. However, this is not a problem at all, especially if the measuring tape and calculator help you quickly and correctly find the result.
How to calculate the area of a square: square formula, web calculation of square meters of surface
Loyalty in calculating the area is necessary not only in order to know how much you need to buy repair materials.
It is also possible to follow the work of experts who will carry out repairs.
Methods for calculating square meters of space
First, in order to measure the surface, you must prepare a measuring tape.
It measures the width and length. The results are multiplied. S is the width along the length. Using note and pencil, the data should be written down.
The calculator gives accurate results. If you calculate the area correctly, you can reduce errors during repairs. This must be taken into account with a standard measuring device. Means for calculating the correct size - provide a guarantee of obtaining the required amount of materials, both final and basic.
Rules to follow:
- If you want to measure an area, it is important that the data is recorded in meters, the calculator helps prevent problems and calculate correctly.
- When the width and length are multiplied, if you want to calculate the size with 100% accuracy, you will need to add bows around the radiators.
- It is important to understand how to determine the size of a space.
There is no need to calculate openings and window doors at the same time. To calculate correctly, you should always use a calculator. Calculating the area in this way is much more convenient.
- Sometimes the problem lies in measuring all kinds of bulges that occur in space. In this case, you can calculate the area of space if you separately measure these structures and determine their total size.
The counter is the same as for the entire surface. If you want to calculate the area of a space, you will need to add all the values obtained. For convenience, you need to take into account, with a calculator at hand.
- Before calculating the surface of a room, you need to read this method: calculate the total number of objects and connect to the addition.
The calculator helps you add and prevent errors.
- There are cases when it is impossible to calculate the area of a room with an irregular shape. Then you need to consider the following: calculate the area of space and divide it into rectangular surfaces. If you take a calculator in your hand, you can calculate the area and add all the resulting areas.
- It happens that it calculates the surface of the space that it divides into rectangles, it does not come out.
Calculate the region of space, while this is true, divide it into other shapes such as a circle or a sector of a triangle. The calculator helps you calculate.
- CORRESPONDENCE Heron's formula can be calculated S in space conventionally divided into sectors or triangles: S (total area) times (p-b) times (r-c).
- To understand how to calculate the square of space if it is divided into triangles, the half-dimension of the resulting triangle must be written as follows: "p" is the same (plus b plus c) for dividing "2".
In this case, the lengths of the sides of the triangle are a, b, c.
- If you want to calculate the area of a space if it is defined as a circle in the calculation, you need to consider the following formula: surface S (total area) = πr2. It should be said that "pi" has a constant value of -3.14.
R is a radius equal to half the diameter of the circle. It's easier to calculate if there is a calculator. You must exclude any errors.
Once all the results are combined, you can get the correct result - the actual total area of the space.
With accurate information, you can safely resume work on the acquisition of materials and repairs.
In the room, you will find an interesting design and use lighting that will beautify the room and provide high quality lighting. It is important to use the most effective ways to organize housing and homes.

According to SanPiN 2.2.2 / 2.4.1340-03, which regulates hygienic requirements for the organization of work, the norm of space per person in an office is at least 4.5 m. In practice, most employers do not adhere to this figure - their employees have to huddle for 2–3 sq. m. Where do office standards come from, why is their non-compliance dangerous for the company, and how to correctly calculate the office area?
Existing area standards for 1 person
The old all-Union standards for living space per person set a conditional minimum of 5 square meters.
m. It was believed that citizens who lived in a room in which each of them accounted for more than this value did not need to improve their living conditions.
Later, the standards for living space per person changed upwards - up to 9, and then up to 12 square meters. m. But not only housing - any human habitat should provide normal conditions for his life.
Modern regulatory legal acts have established several sanitary and epidemiological requirements for office premises that prevent the emergence of a threat to the health and life of employees:
the mentioned area standard for 1 person is 4.5 sq.
m. refers to a workplace that uses a computer with a flat liquid crystal (LCD) screen;
the same area is provided for each employee of the design bureau, regardless of whether he works on a drawing board or a computer;
in SNiP 2.09.04-87, the standard for office space per person from a low-mobility group (disabled) and moving in a wheelchair is specified - 5.65 and 7.65 sq.
the presence of auxiliary devices for general use - a printer, a large monitor, a scanner, a fax machine, etc.
How to calculate square meters. How to calculate square meters?
- this is another reason to increase the area.
If the duration of a person’s work does not exceed 4 hours, it is allowed to reduce the area due to him to 4.5 square meters. m or equip the so-called hot desk (a desktop not assigned to a specific employee).
Why employers should follow the rules
Employees who are dissatisfied with the created working conditions have the right to initiate an audit from an independent organization, labor inspectorate or trade union.
If the claims are confirmed, the violator is obliged to pay compensation and / or provide increased leave.
The thoughtless desire to save on rent or purchase of office space by cutting the area standard for 1 person is a direct path to the emergence of critical moments for doing business:
growing discontent in the team;
gradual decrease in motivation and performance;
the imposition of penalties and fines, possible during the certification.
Estimate the number of employees and office equipment and calculate the required area according to the norms.
2. Determine the number of passages between tables with a width of at least 2 m.
3. Approximately find out the number and dimensions of auxiliary furniture and equipment.
4. Take into account the area of the dining area, reception areas for visitors, security post, etc.
By summing up the data obtained, it is possible to bring the area of the office to the norm and thereby avoid violation of the law.
