How to find out the area of ​​a room in square meters - how to calculate the area of ​​a room, how to find out the square footage of a room: how to measure a room in m2

Room area in square meters

It’s not difficult to calculate, you just need to remember the simplest formulas and also take measurements. For this you will need:

• Roulette. It’s better with a lock, but a regular one will do.
• Paper and pencil or pen.
• Calculator (or count in a column or in your head).

A simple set of tools can be found in every household. It’s easier to take measurements with an assistant, but you can do it yourself.

First you need to measure the length of the walls. It is advisable to do this along the walls, but if they are all filled with heavy furniture, you can take measurements in the middle. Only in this case, make sure that the tape measure lies along the walls, and not diagonally - the measurement error will be less.

Rectangular room

If the room is of the correct shape, without protruding parts, it is easy to calculate the area of ​​the room. Measure the length and width and write it down on a piece of paper. Write the numbers in meters, followed by centimeters after the decimal point. For example, length 4.35 m (430 cm), width 3.25 m (325 cm).

How to calculate the area of ​​a room

We multiply the found numbers to get the area of ​​the room in square meters. If we look at our example, we get the following: 4.35 m * 3.25 m = 14.1375 sq. m. In this value, usually two digits are left after the decimal point, which means we round. In total, the calculated square footage of the room is 14.14 square meters.

Stylistic decisions

When decorating a room of 12 square meters. Preference should be given to minimalist directions. Interiors in the spirit of Art Nouveau, Provence, and classics will be perceived well. You can try to reproduce country music. But in this case, you need to try not to overdo it with the play of colors and interior decorations.

Background surfaces when designing a room of 12 square meters. It’s better to decorate it in one shade spectrum and texture, preferably in wood, although you can also resort to wallpaper with a floral print. This will make the room more voluminous. The atmosphere is uniquely cozy and looks quite modern.

A single tint spectrum will visually increase the space

To revitalize the atmosphere in the interior of a room of 12 sq. m use richly colored paintings or other accessories characteristic of the style. Wrought iron furniture is suitable for furnishing. Non-bulky designs should be distinguished by functional diversity. For high ceilings, it is advisable to use beams in their decor.

Bright accents will enliven the interior of the room

The classics are always refined and relevant. She manages to maintain the sophistication of the decor even in the design of a small space. A smooth standard white ceiling, parquet flooring, ornamented wallpaper, high-quality modular furniture - the basis of the style remains unchanged.

Classic style is ideal for small spaces

Provincial trends are also distinguished by the abundance of decorative elements and the presence of flowers, but at the same time there are absolutely no signs of modernity in the setting. The floor is covered with untreated boards, and the walls are simply plastered. Complements the interior of a room of 12 sq. m furniture of classical design.

Stylish and discreet modernism is also good for modest abodes. It is extremely harmonious. Its highlights: 3D textures, suspended ceilings, discreet background decoration of floors and walls. The abundance of furniture is inappropriate. It is customary to add the most necessary things to the interior.

Harmonious minimalist style in the interior

Minimalism in design 12 sq. m - the kingdom of simplicity and practicality. Light colors, the practical absence of furniture and the need for zoning areas, the asceticism of accessories, lamps in ultra-fashionable decor, and the naturalness of finishing - all this makes the style in demand not only by young people.

Room 12 sq. m. – simplicity and practicality

Any stylistic version is not difficult to implement and is ready to remain relevant for many years.

What dimensions are needed for calculations?

So, what measurements will you need to take to determine the area of ​​the room? The answer is simple - everything that touches the perimeter of the room, and it doesn’t matter whether the room is geometrically flat or has a lot of niches and corners. Generally speaking, to calculate the area of ​​any room you will need its length and width.

Basic room dimensions

What tools are used to calculate areas?

To calculate the area of ​​a room, you can use various computer programs, and various mathematical formulas are also used for calculations. But the dimensions of the sides of the geometric figure that the room corresponds to will have to be taken in any case.

Table. Tools for taking room dimensions.

NameRecommendations

Manual calculation on a piece of paper is convenient because all parameters can be immediately measured on the spot and the necessary adjustments can be made. But it’s quite easy to make a mistake with the manual calculation method, so it’s better to recalculate all the indicators once again.

On a note! It is better to re-measure the room if you are unsure of the readings than to end up buying an insufficient amount of material or purchasing it in excess.

To automatically calculate the area of ​​a room, it is convenient to use various graphic editors. This could be AutoCAD, ArchiCAD or SketchUP. They create a figure according to the shape of the room, the dimensions of all its sides are indicated when creating the layout. The area of ​​the room will be displayed by the program automatically and with high accuracy (down to centimeters and millimeters). Everything will depend on the accuracy of the measurements taken. The use of these programs is especially recommended if it is necessary to calculate the area of ​​a room with complex geometry. The disadvantage of this method is the need for at least a superficial study of programs, as well as the use of computer equipment.

Example of using SketchUP program

Step-by-step calculation of room area

Step 1. First of all, you need to prepare all the measuring tools, as well as a piece of paper and a pen. On paper, you can first draw a diagram of the room, trying to preserve the geometry as much as possible and display all the niches and details of the room. The tape measure used is as long as possible.

Preparing everything you need

Step 2. Measure the length of the room. If it is so large that there is not enough tape measure, then measurements are taken in stages. To begin with, a measurement is made to the maximum length of the tape measure, a mark is made at the end of the tape, from which the measurement is then made again to the end of the room.

First you need to measure the length of the room

Step 3. Measure the width of the room (along the shorter wall). The tape measure is positioned at right angles to the previously measured wall of the room (length). The received data is recorded.

The width of the room is measured

Step 4. The obtained indicators are multiplied among themselves. For these purposes, it is recommended to use a calculator. If necessary, the area value is rounded up.

The resulting figure is rounded up

Step 5. If you need to measure the area of ​​a geometrically complex room, then first the complex figure is divided into several simple ones - squares, triangles, rectangles. The object is depicted schematically on a piece of paper and divided schematically.

The room is divided into 4 rectangles

Step 6. Each figure is measured separately. For example, rectangles, triangles.

Each figure is measured separately

Step 7. The area of ​​each figure is calculated. Next, all the obtained values ​​are summed up and the total exact floor area of ​​the room is obtained.

How to calculate the area of ​​the walls of a room

The procedure for calculating the area of ​​the walls and floor is different. The fact is that before calculating the square footage 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, first find out the perimeter of the room and multiply it 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. At the same time, one should not forget about the squaring of window and door openings. Their area is subtracted after completing the wall calculations. But on the other hand, they can be ignored and thereby provide a certain supply of materials.

How to calculate the square footage of walls

Determining the area of ​​walls is often required when purchasing finishing materials - wallpaper, plaster, etc. This calculation requires additional measurements. In addition to the existing width and length of the room you will need:

• ceiling height;
• height and width of doorways;
• height and width of window openings.

All measurements are in meters, since the square footage of walls is also usually measured in square meters.

It is most convenient to put the dimensions on the plan

Since the walls are rectangular, the area is calculated as for a rectangle: we multiply the length by the width. In the same way, we calculate the sizes of windows and doorways, subtract their dimensions. For example, let's calculate the area of ​​the walls shown in the diagram above.

1. Wall with door:
   2.5 m * 5.6 m = 14 sq. m. - total area of ​​the long wall
2. how much does a doorway take up: 2.1 m * 0.9 m = 1.89 sq.m.
3. wall excluding doorway - 14 sq.m. - 1.89 sq.m. m = 12.11 sq. m
4. Wall with window: square of small walls: 2.5 m * 3.2 m = 8 sq.m.
5. how much does a window take: 1.3 m * 1.42 m = 1.846 sq. m, round up, we get 1.75 sq.m.
6. wall without window opening: 8 sq. m - 1.75 sq.m = 6.25 sq.m.

Finding the total area of ​​the walls is not difficult. Add up all four numbers: 14 sq.m + 12.11 sq.m. + 8 sq.m. + 6.25 sq.m. = 40.36 sq. m.

How to calculate floor area?

So, how do you calculate square meters? The simplest ones to formulate the floor area are square and rectangular shaped houses. To calculate the area of ​​such a room, you need to measure the length and width of the room (measured in meters), and then multiply these two numbers by each other, obtaining the number that interests us. This option is not difficult to implement; there is no need to rearrange the sofa, wardrobe and other furniture - all you need to do is calculate the distance. The only problem will be a fireplace (if there is one, of course) in this case, it will be necessary to subtract S (area) of the fireplace from the final figure.

Irregularly shaped rooms present a more complex calculation of the S floor. An apartment in the shape of a rectangle or square is called standard, however, if there are decorative changes (arches, niches), then the calculation is more complicated, since it requires the calculation of S figures included in the room.

First, the plan must be divided into two rectangles, and then their areas must be summed up

By calculating the final area of ​​“non-standard figures”, for example, an L-shaped room, you can “split” the room into two squares or triangles and sum up their sum. This little trick allows you to find out the S of a given area in a matter of minutes without any mathematical calculation formulas. In some cases, the corner of an L-shaped room does not meet at an angle of 90º, which is a small but solvable problem. Intersecting at an indirect angle, the transition has the form of a triangle; the calculation must be carried out according to the familiar geometric law: “The area of ​​a triangle is equal to the first leg multiplied by the second.”

Cylindrical and half-segmental particles, but how to calculate square meters based on a basic algebra and geometry course? It is much easier to divide the area into conventional triangles and squares, and then calculate and summarize the results of each individual element.

Formulas for area and geometric figures

There are living rooms in private houses that have different floor heights (protrusions, hills, slopes). To perform the calculation, it is necessary, as in the previous case, to divide the areas into individual elements, measuring each separately and summing up the results.

A tape measure is the best tool to help you calculate the S floor. However, in addition to the tape measure, you need to take a piece of paper and a pencil and write down the measurements, and only then carry out mathematical calculations (so as not to confuse and measure everything ten times).

Advice

Do not take measurements on the wall, as it may have defects and lead to inaccurate measurements. Places that have protrusions in the form of semicircles or zigzags should be counted separately.

Triangles

It is easiest to deal with rectangular representatives of this family. Having drawn it on paper, it is easy to notice that it is half a rectangle. Accordingly, the calculation formula differs slightly: S=a*b/2. Where the letters a and b mean the length of the legs (sides touching at right angles).

If the triangle does not have right angles, the following steps must be taken:

• take one of its sides as a basis;
• draw a height from the top to it;
• multiply one by the other;
• divide the result by 2.

As a result, the formula will look like this: S=a*h/2. Where a and h are the base length and height, respectively.

For exotic lovers, there are other options. For example, Heron's formula, or calculation using the radius of a circle inscribed in a triangle. But it will still be easier to count through the base and height.

Circles and ovals

Such geometric shapes are rare in construction, but they do occur. To calculate the area of ​​a circle, just find its radius and substitute it into the equation: S=πr2. We have known it since school. And, according to textbooks, r is the radius of the circle, and the value of π is 3.14.

The area of ​​an oval (ellipse) is calculated in a similar way. Only instead of the radius, you need to find the length of its two semi-axes - long (a) and short (b). Further - according to the same scheme: S=π*a*b.

But more often you can encounter semicircular or “semi-oval” rooms. To calculate the size of such a room, add /2 to the formulas for a circle and an oval at the end. In Latin it will look like this: S=πr2/2 and S=π*a*b/2.

How to calculate the area of ​​a room: calculation method by floor

You can calculate the floor area. This procedure consists of the following steps. First of all, it is necessary to clear the walls of the room. It is better to take measurements in an empty room. If the room is rectangular, then you can multiply the two sides. In reality, the sides may differ slightly, which is why it is important to measure all sides. In some cases, the room may not be configured correctly. In this situation, the entire space is divided into separate rectangles. In this case, you can draw a diagram with all dimensions. Then the area of ​​individual plots is calculated. By the way, the room will not necessarily consist only of rectangles. It can contain triangles and even circles.

In the table you can see the correspondence of the area on the floor with the indicators for the walls at a certain ceiling height

If you don’t know how to calculate the square meters of a room, you can use a special calculator. When calculating dimensions, it is not necessary to observe all dimensions down to the centimeter. Rounding of values ​​is often used. Sometimes it is necessary to take into account various recesses and protrusions in the walls.

When making calculations, it is important to take into account their purpose. If you need to find out the values ​​​​for installing a heated floor, then you can not take into account the space occupied by heavy furniture.

There are options when different floor levels are used in the room. In such a situation, it is also necessary to divide the room into separate zones. You should not take measurements on the wall, as it may have a curved surface.

It is difficult to determine the area based on the floor, which has various protrusions in the form of waves or semicircles.

Floors with complex configurations require special care and the use of special formulas

For your information! If the room is L-shaped, then in addition to two rectangular figures there is also a triangle. To determine its area, you can multiply one leg by the other.

Measurements

Before measuring a room in square meters, you need a minimum set of items:

• calculator;
• roulette;
• pencil;
• paper.

You need to make a detailed floor plan on paper. Each wall should 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 slightly tilted to one side. Since the floor is being measured, it is necessary to measure as closely as possible to the walls.

The second stage is to put 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 by linear metres.

Rounding can only be done if the increase is small, so that in case of unforeseen circumstances, there is a sufficient amount of material.

How to calculate the square footage of a room

To understand how to find out the total area of ​​a room, you need to use a simple formula and multiply the length by the width. As shown in the figure, the long wall has a length of 7 meters and the opposite one is only 4. It turns out that the floor area will be equal to 28 m2. This is how the quadrature is found. It is imperative to remember the small reserve that will be required for adjustment and trimming, and the more complex the installation option, the more reserve you will need to take.

Proportions between floor and window area

According to SNiP 01/31/2003, the parameters of windows and their number should depend on the square footage of the floor. So for residential multi-apartment buildings, the ratio between the areas of window openings and the floor surface will range 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 02/31/2001. According to this documentation, for every 8 “squares” of floor surface there must be at least one “square” source of natural light flux. On attic floors this proportion cannot be less than 1:10.

To ensure high-quality repairs, you need to figure out in advance how to calculate the floor area and other necessary dimensions of the room. The preparatory stage also involves the purchase of building materials, and then during the repair process, costs will be kept to a minimum, since there will be no large leftovers and the cost of delivery will be inexpensive.

The manual method of calculating how to find out the floor area will take more time than when carrying out calculations on an existing construction calculator, but it allows you to find out more accurate results.

How to calculate the area of ​​a room that has niches and projections?

What to do if there are various niches or columns in the room that cannot be hidden or dismantled? In this case, you will have to tinker a little with the calculations, since from the values ​​of the total area you will have to calculate the indicators of the areas that these same columns occupy, and add the area of ​​each niche to the result.

Calculation of the area of ​​a room with a cutout

In this case, it is most convenient to depict on paper the exact shape of the room, indicating all the projections, niches and columns. Next, measurements are taken of the long and straight sides of the room and written down in the appropriate place on a piece of paper. After this, the perimeter of each column is measured and the area of ​​each column is calculated using the above formula (S = A x B). Next, the parameters of the area of ​​each niche are calculated in separate blocks using the same principle.

Then everything is simple - the main area is calculated, i.e. the length and width of the longest walls are multiplied. The areas of the columns are subtracted from the resulting value, and then the niche areas are added to the result. We get the exact area of ​​the entire room.

In some cases (for example, a room is made in the shape of the letter “L”), you can visually divide the room into several even shapes (for example, rectangles), take measurements of each shape separately, then calculate the area of ​​​​each element and sum up all the obtained values.
