Cabinet area in square meters. required to measure the area. How to calculate the area of \u200b\u200bthe room: the procedure.

When starting any renovation, you need to know how to calculate the area of a room. This knowledge will help you choose correct amount materials, as well as correctly calculate the dimensions. Such knowledge is also necessary when purchasing real estate, when you need to check the area indicated in the documents.

Our review will help you remember school knowledge and tell you how to put it into practice. In addition, you can use a special calculator.

When calculating the areas of the ceiling, floor and walls, you need to figure out how to calculate the square meter. For calculations, you must select a measuring tape or tape measure with divisions in centimeters or meters. Such a device is used for an area in square meters.

If the value is greater than a meter, then not only meters, but also centimeters are used.

To correctly carry out the calculations, you can use the calculator of square meters. If necessary, measure the entire length, you can do this in stages. For example, make a mark where the tape measure ended, and then stretch it again.

The width is also measured with a tape measure. At the same time, it is placed at an angle of 90 degrees to the length. If the length is less than a meter, then it is necessary to round to the nearest centimeter.

When calculating square meters with a calculator, it is not always possible to take measurements in meters. The indicator is displayed both in meters and in centimeters. In this case, 1 cm equals 0.01 meters. For example, 98 cm is equal to 0.98 m. That is, you can write 2.98 m. To get the area, you need to multiply the length by the width. You can round the value up.

It is worth noting other units of measurement:

in 1 square pound - 0.093 square meters;
in a yard - 0.84 square meters. m.

an accurate calculation of materials for repairs is required;
hired craftsmen often carry out calculations of payment per square meter, which must be double-checked to exclude fraud;
knowledge of calculations is required when choosing an area. Often utility bills are calculated based on the size of the room;
to determine the standards of illumination, you also need to know the dimensions of the room;
knowing the area, you can always calculate the volume, which is very important when installing heating, ventilation and climate control devices.

The video gives a simple explanation of the required values:

Note! To calculate the area of a room of a complex configuration, you can divide a complex figure into simple shapes. After that, you need to find out the area of \u200b\u200beach figure, and then summarize these results.

How to prepare for calculations

Carrying out preparatory manipulations consists in preparing a place for measurements. It is also necessary to prepare the tool and special accessories. It is better if the room is free from foreign objects. Often this happens when measuring in a new house or during repairs. Measurements of the length of the sides are made along the walls. In this case, you need to free up at least some areas for free holding of a tape measure. The measurement results can be immediately transferred to the diagram. Be sure to check the squareness of the room. For this, diagonal lines are measured.

In addition to a tape measure, you may need a special ruler to check straight lines. It can be a building level or a rule. Sometimes a large construction square is needed. Alternatively, a homemade compass. You can use a piece of cord tied to a sharp pin. For the floor, special measuring accessories can be used. For this, a marker, chalk or adhesive tape is suitable. Take measurements several times. This will avoid the error. Make sure that the measuring tape does not sag. Remember that many measuring instruments have two scales. Do not confuse the metric system and inch.

Before measuring, sketch out a simple plan - a diagram on paper. This will allow you to correctly distribute all the measurements. It should be borne in mind that many calculation formulas are very complex. In this case, it will not work to count in a column. To calculate without errors, you can use Excel.

Note! Professionals for different dimensions use special laser roulettes. With their help, you can quickly measure the angular and linear values. In some designs, options are provided to carry out the necessary calculations.

How to calculate the area: basic options

Find out how to find out the area of \u200b\u200bthe room. It is impossible to do this according to the technical passport, since it contains general data for the entire apartment. And the parameters must be calculated for each individual room.

If the room looks like a square or rectangle, then you can use this formula for calculating the area.

S=A*B, where

BUT and AT the sides of the rectangle.

To take the correct measurements, you need to move all the furniture away from the walls. In this case, the resulting value is expressed in square meters.

If the shape of the room is incorrect, then you need to put on paper a diagram of the room, but in compliance with all proportions. How to calculate the area will help the division of the scheme into simple geometric shapes. Using a tape measure, all elements are measured, and then the areas of all figures are calculated. After that, all areas must be folded.

Definition of individual plots:

to calculate the value of a rectangular configuration, you need to multiply the width and length;

the area of a square is equal to its squared side;

area of a triangular shape - multiplying the side by the height, and then dividing by two;

To calculate the area of a circle, multiply the radius squared by pi.

All the resulting areas can be added up if the room consists of them.

How to carry out simple calculations, you can watch the video:

To perform calculations using a calculator, you also need to measure the width and length of the room. All measurements must be made in meters. Also, with the help of this device, you can calculate the dimensions of door and window openings.

Important information! When performing calculations for a room with ledges, columns and niches, it is necessary to take into account their location and configuration.

How to calculate the area of a triangle

Let's figure out how to calculate the area of a triangle. If there is an element in the form of a right angle in an irregularly shaped room, then the following formula can be applied:

S=(a*b)/2;

There are other options for calculations. To calculate the area of a triangle, you can first determine the quadrature of the rectangle, and then calculate the area of the triangular corner. Then the value of the triangular part is subtracted from the quadrature of the rectangle.

If there is no right angle, then you can use Heron's formula:

S=√p(p-a)(p-b)(p-c);

Wherein a, b, c represent the sides of a triangle, and R- semiperimeter. To find out, all sides should be summed up, and then divided by 2.

To calculate the area of a given figure, you can multiply the length of the base by the height drawn from this base, and then divide the result by 2.

How to find the area of a rectangle

Often there are rooms that look like a rectangle. To calculate the area of a rectangle online calculator considered the most the best option. But simple calculations can be done independently. There should be no protruding parts. Measure the width and length. Entries must be made in meters.

To calculate the area of a rectangle, you need to multiply the obtained values. After the decimal point, you can leave only two digits, and round the rest.

The question often arises of how to calculate the area of a rectangle if there are niches. In this case, the space is divided into several figures, and they are considered separately. There is another formula for calculating area. In this case, the perimeter of the room must be multiplied by the height. To calculate the perimeter, you need to add the length and width, and then multiply them by two.

How to calculate the area of a trapezoid

To calculate the area of a trapezoid, it is important to know the lengths of the two parallel sides, as well as the height. In this case, the height is the perpendicular between the sides.

Here is a formula you can use:

S=1/2(A+B)*h;

It should be borne in mind that nothing will change from the angles of the sides. But the height is recommended to measure in several places. This approach will make sure that the two sides are parallel.

Knowing such a formula is also useful when calculating the areas of premises of polygonal configurations. For example, an unusual space can be divided into a rectangle and a trapezoid.

There is also a special calculator for calculating rectangular and trapezoidal rooms. In this case, the difference is that the length of the rectangle will be the same. If necessary, you can make adjustments with the existing ledges and niches.

To determine the perimeter, you need to measure the lengths of the four sides, and then add them.

How to calculate the area of a circle

Sometimes it is required to calculate the area of a circle, since there may be separate sections of rounded configurations in the room. Such knowledge will also be useful when calculating arched door or window openings. Consider shapes based on a circle. Most often there are segments, quarters of a circle or semicircles.

Such calculations are necessary if there is a bay window or a combination of a balcony with a room. In this case, the value of the protruding circle is first determined, and then the resulting indicator is added to the rest of the area.

The following formula is used to calculate the area of a circle:

S=πR²/2,

π equals 3.14. BUT R² is the radius of the circle squared.

Correct calculation of the sector and segment area

A special formula for the area of a sector of a circle is included in the calculator for calculations. Such a formula looks like this:

S= R²*arcsin(c/2R)-0.25*C*√(4 R²-C²);

How to calculate the area of a room: a method for calculating the floor

You can calculate the floor area. This procedure consists of the following steps. First of all, you need to free 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 the correct configuration. In such a situation, the entire space is divided into separate rectangles. In this case, you can draw a diagram with all sizes. 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.

If you do not know how to calculate the square meters of a room, then you can use a special calculator. When calculating the dimensions, it is not necessary to observe all dimensions up to a centimeter. Rounding is often used. Sometimes it is required to take into account different recesses and ledges in the walls.

When calculating, it is important to take into account their purpose. If you need to find out the values \u200b\u200bfor installing a warm floor, then you can ignore the space occupied by heavy furniture.

There are options when used indoors different levels gender. In such a situation, it is also required to divide the room into separate zones. Do not take measurements along the wall, as it may have a curved surface.

It is difficult to determine the area by the floor, which has a variety of protrusions in the form of waves or semicircles.

Note! If the room has L-shape, then in addition to two rectangular figures, it also contains a triangle. To determine its area, you can multiply one leg by another.

How to calculate wall area

To determine the area of the walls, you need to know how to calculate the perimeter of the room. Determination of the area is often required for the purchase of all kinds of finishing materials. In addition to the length and width of the room, you will need to find out the height of the room, as well as the dimensions of the door and window openings.

When calculating, it should be borne in mind that the height of the ceilings, even in one room, can vary, especially if the room is an attic type. The values of all walls are calculated separately, and then window and door openings are subtracted from them.

The exact values can be determined using the calculator for calculating the area of \u200b\u200bthe walls of the room. Sometimes you need to determine the volume of the room. In such a situation, it is necessary to multiply three values: the length, width and height of the room. This indicator is measured in cubic meters.

If the room has a multi-level zoning, then you can carry out the following calculations:

measure all sections of the walls. Measurements are recommended to be taken closer to the ceiling;
calculate floor area indicators;
on each vertical section it is necessary to measure the length and height, and then multiply these values;
add the indicators to the gender value.

Each room has optimal parameters which can be taken into account when planning a construction site. The minimum living space is 8 sq. m. Room general purpose, such as a hall or living room can have an area of 14 to 25 square meters. m. The minimum height of the room is 240 cm. If the ceiling is more than three meters, then such a space is more difficult to heat. The kitchen must have an area of at least 6 square meters. m.

The correct calculation of the area of the room is a guarantee of high-quality repairs. This approach will minimize the cost of purchasing materials.

When repairing a residential building, it is required to calculate the area of \u200b\u200beach of its rooms. This will help you buy Construction Materials in the right quantity and correctly calculate the budget for repairs. As a rule, if you have simple tools, it will not be difficult to measure the area of \u200b\u200bany room.

How to measure the area of a room

To measure the area, you need

Roulette construction;
Notepad or regular sheet of paper;
Pen (or better a pencil);
Calculator.

Procedure

The easiest way to calculate the area of rectangular rooms. It is enough to measure the length and width of the room using a regular tape measure and multiply them together (before that, you need to convert the resulting numbers into meters). It is important to record all measurements in a notebook, marking the rooms to which they relate. Otherwise, at the end of the process, you will have to remember which room, which area.
The situation is more complicated with the calculation of the area of those rooms that have ledges, niches or an irregular shape. Here you should proceed as follows: you need to divide the space into rectangles of the correct shape and calculate the area of \u200b\u200beach in the way we already know (point 1). Then, adding up all the data, we get the area of the room.
If there are columns and other decorative elements in the room, it is required to subtract the area they occupy from the total area of the room. To do this, they are measured with a tape measure (not in a circle, but in a straight line, figuratively outlining a square around the column), and by multiplying the length and width, the area of \u200b\u200bthe column is obtained.
In a similar way, the area of \u200b\u200bwalls is calculated for calculating the purchase of finishing materials. Multiply the length of the wall by its height and subtract the area of the windows and doors.
The area of the room during the finishing work may change. This is facilitated by some materials, such as drywall. When using it during repairs, it should be borne in mind that the total area of \u200b\u200bthe room will decrease upon completion of work.
All measurement results, before and after repair, should be stored in a specially compiled table. This will help you not to take measurements every time you need to find out the area of \u200b\u200bthe room.

A similar calculation method allows you to measure any area of \u200b\u200bthe house or land plot. More information can be found in the article -

We received a question from Viktor Vladimirovich: “How is the area of the room being repaired calculated?”.

Quadrature is a little-known mathematical term that originally meant finding the parameters of the area of a figure or a given type of surface. Repair work is a troublesome task that involves a high-quality and correct calculation of the square meters of the room to be updated. At the moment, in the public domain, you can find a calculator that allows you to correctly calculate the amount of required building and finishing material.

Carrying out independent calculations

Before you calculate the area of the room, you need to prepare a tape measure, pencil or pen, calculator, long rail or building level, which will help you calculate the full quadrature of the room to be repaired. All calculations are based on certain calculations.

Calculate the square of the walls of the room

It is possible to calculate the area of the room in full only by determining the exact dimensions of the walls, floor and ceiling. To count the walls, you should apply a tape measure along all the skirting boards that run along the floor of the measured room. The number of meters received should be recorded.

Calculate the square of window and door openings

At this stage, you will again need a tape measure and a calculator. Parameters of the area of window openings in meters are measured by window slopes and its window sill. For the height in meters, side slopes are measured, and the width is measured along the length of the sill. The quadrature of a non-standard window opening can be calculated by the formula:

S \u003d 0.5A x H, where A are the window width indicators, and H are the parameters of its height.

By analogy, the area of \u200b\u200bany doorway is calculated.

Calculation of floor and ceiling squaring

At the next stage, you should find out how many meters the floor area in the room occupies. The opinion that the number of square meters of the floor always corresponds to the parameters of the ceiling is erroneous. However, if the room has a standard shape and is not complicated by architectural solutions, then the formula for calculating both floor and ceiling is as follows:

S \u003d A x B, where the values \u200b\u200bof A and B are represented by the lengths of adjacent wall surfaces with a common angle.

The quadrature of a standard floor is calculated according to the same principle as the quadrature of the ceiling surface. The calculator allows you to calculate how many meters is the area of the floor and ceiling separately.

It should be borne in mind that the basis of all calculations is a square meter of area. The calculator can be useful at all stages of calculations.

Alternative ways to get data

A fairly promising and convenient way to calculate the quadrature of a dwelling is to use some special programs. The category of the most popular includes a construction calculator in the online version, which allows you to calculate the quadrature of any type of area. The indisputable advantage of such calculations is the ability to obtain data in the desired format, since the calculator automatically converts units to meters and vice versa.

If there is no self-confidence, then there is always the opportunity to seek help from experienced professionals who, for a very reasonable fee, will competently make all the calculations necessary at the repair stage.

How to calculate the area of \u200b\u200bthe walls in a room (video)

Repair is troublesome, but pleasant, because after it an apartment or a private house become more comfortable, modern, conducive to relaxation. "How to calculate the area of \u200b\u200bthe room and walls?" - this is perhaps one of the first questions that arise on the horizon of alterations.

You can not do the calculations yourself, but entrust this matter to a team of finishers who will carry out repairs. But what if the decision is made, and all the work will be done by hand? In this case, the calculation must be especially careful, since the lack of experience may be the result of a shortage or excess of one or another material.

The beginning of the repair - taking measurements of the walls.

A lot of calculators have appeared on the Internet that allow you to calculate completely different building values: geometric dimensions, volumes, weight, usable area. But it is not always possible to calculate m2 using programs. In this case, you have to use the usual calculation method.

To carry out the calculation you will need:

roulette;
pencil or pen;
calculator;
long rail or building level

Before starting measurements, you should free two walls from furniture, since you can calculate the area of \u200b\u200bthe room completely - walls, ceiling, floor - by knowing the exact dimensions of the walls.

5.5 x 3 = 16.5 sq.m.

Similarly, all remaining walls must be measured and calculated. If there are roundings or other complex configurations, the wall is divided into several areas and each of them is calculated separately.

Most often, in apartments, wall decoration consists in gluing them with wallpaper or painting. The obtained values of the area of \u200b\u200bthe walls will be needed when calculating building materials.

How to find out the area of windows and doors?

The area occupied by windows is measured by slopes and window sills. The height of the window is determined by the side slope, the width - by the window sill or upper slope.

For example, the width of the window is 1.55 m, the height is 1.65 m.

1.65 x 1.55 = 2.56 m2

If there are several windows, their total area is summed up.

Triangular window area: S = 0.5A * h, where A is the bottom side / width of the window, h is the height.

If the width of a triangular window is 2 meters and the height is 1.5 meters, then the area of the window will be:

0.5 x 1.5 x 2 = 1.5 m2.

The area of doors, like the area of a rectangular wall, is measured by simply multiplying the width of the door by the height. The measurements taken on the box, and not on the canvas, are taken as the basis.

The correct calculation of wallpaper on the walls.

If there are no patterns on the wallpaper that require selection, and their gluing is done without overlapping in width, then you can buy as much m2 as you can by simply summing up the areas of all walls, minus windows and doors. The area of the tube is always indicated on the package.

For insured event any wallpaper, even calculated with particular accuracy, is purchased with a margin. The manufacturer may stop producing them, and minor damage, for example, from the creativity of children, will want to be fixed immediately.

If the wallpaper provides for an overlap in width, then the value of the usable area of one tube should be indicated on the package. It is necessary to proceed from this figure.

When choosing a wallpaper with a pattern that needs to be adjusted, the calculation is carried out taking into account the shift and the margin for leveling the rapport.

The above examples explain how to calculate the area of a room for walls to be wallpapered or painted. This is followed by measuring the area of the floor, ceiling and the total area of the apartment or room.

How to calculate floor and ceiling area?

The area of the ceiling is usually equal to the area of the floor, so it is enough to deal with the measurement of one value.

An example of calculating the area of a room by determining the area of \u200b\u200bthe floor.

The room is 5.5 meters long and 3.5 meters wide. We multiply the length by the width: 5.5x3.5 = 19.25 m2.

The floor area was 19.25 m2.

The ceiling area will be the same. Paint, putty for finishing the ceiling are calculated based on this value, taking into account the margin, the number of layers, wallpaper for the ceiling - according to the example of calculating the walls.

Determining the total area of a room or apartment.

The values of the total area of the premises in which the repair will be carried out are used by foremen to issue a preliminary estimate to the customer. There is an average price for a complex repair for 1 sq.m., you can be guided by it when choosing a contractor.

(A + B + C + D) x h \u003d S - total area; A, B, C, G - sides of the room; A, B - 5.55 m; B, D - 3.5 m;
(5.55 + 3.5 + 5.55 + 3.5) x3 = 54.3 m2;
Subtract the area of windows and doors from the total area of the room.

By carrying out such measurements in all rooms, you can determine how to calculate the area of \u200b\u200bthe apartment.

Determination of the total and living area of the apartment.

In order to find out the total and living area of the apartment, you will need to take measurements of all rooms, including balconies, storage rooms, built-in wardrobes, etc.

The documents received together with the warrants and keys to the apartment should reflect all the information about the residential and non-residential area, but in practice it is often necessary to re-calculate.

So, how to calculate the living area of an apartment? For this, the areas of all living rooms are measured in stages. A living room or dwelling is considered to be a premise suitable for a permanent place of residence that meets sanitary and technical rules and regulations. This is a living room, bedroom, children's room. Non-residential rooms are corridors, pantries, kitchens, bathrooms.

Knowing the size and area of all non-residential premises is necessary to determine the total area of \u200b\u200bthe apartment. There is also the concept of heated and unheated area of the apartment. It is also closely related to the value of "total", since to calculate total area apartments, according to the rules, you can, knowing this footage.

The total area includes the area of all residential and all unheated premises: balconies, loggias, cold storerooms, built-in wardrobes or wardrobes. To include verandas, loggias and balconies in the total area, reduction factors are applied. For loggias - 0.5; verandas and pantries - 1.0; for balconies and terraces - 0.3.

Competently carried out calculations will help to prepare for any repair, optimize the cost of purchasing materials, as well as control the cost of paying master finishers.

Professionals - it is, of course, easier. They have a trained eye and a tool. But for those who do not have a construction education, but due to circumstances decided to do repairs on their own, sometimes they have to rack their brains over the seemingly simplest tasks. Here, for example, is such a question: how to find out the area of \u200b\u200bthe room? And now the layman nervously draws lines on paper or paces back and forth around the room, fiddling with a meter tape measure ... Oh, I should have listened more carefully to the geometry teacher!

But there is no time for lyrics - the repair itself will not be done. Therefore, we will quickly consider all the nuances, and at the same time we will talk about cases when, in general, this same area of \u200b\u200bthe room is so necessary.

Equipment

Before we start taking measurements, we will arm ourselves with the following simple devices:

roulette or;
pencil or crayon;
notebook with a pen;
calculator.

Make sure everything is at hand. Do not rely on memory and phenomenal abilities - immediately write down the numbers and count on the calculator. The values obtained will most likely not be round, and it will not be easy to work with them in the mind.

Hint from the textbook

The area formula is one of the few knowledge gained in school that most people remember all their lives. You just need to multiply the length and width - nothing complicated.

Therefore, before knowing the area of the room, we simply measure the lengths of the walls. We multiply the obtained values, and here it is the result!

“But not all rooms have the shape of a rectangle and a square,” an inquisitive reader will certainly notice ... That's right, so let's try to crank up the trick in rooms with an unusual layout.

A circle

Modern architecture sometimes amazes with non-standard solutions, so you should not think that only the throne room in the castle of a pretentious king or the hall in a hotel can be round. For example, a homeowner in a fashionable new building or a person who bought an apartment after redevelopment can face this. Again, we recall the geometry course and write the formula in a notebook: S = πR².

In practice, measuring the diameter is easier than finding the radius, because for the latter you need to know exactly where the center is. And to find the diameter, just fix the edge of the measuring tape near one wall, move to the opposite one and, by trial and error, find the point as far as possible from the beginning of the tape.

Divide the resulting value in half, square and multiply by 3.14. Here is the area of the round room.

How to find out the area of a room of irregular shape

Let's look at an example for greater clarity. Let's say we have a room in a small apartment - "living room", in which you need to find out the area of \u200b\u200bthe living room:

We do the following:

we measure wall 1 and wall 2, write down the obtained values;
multiply x: 7 x 3.5 = 24.5 (m 2);
we measure walls No. 3 and 4;
multiply: 1.5 x 2.5 = 3.75 (m 2);
subtract from the first value obtained "extra area": 24.5 - 3.75 \u003d 20.75 (m 2).

As you can see, again, nothing complicated!

Scope of application

And why are we even trying to understand how to find out the area of \u200b\u200bthe room in square meters? Let's decide what materials this is useful for calculating. Of course, we are talking about materials for the floor and ceiling. So, this value is needed when applied:

plaster mixture;
primer, putty;
dye;
the liquid wallpaper;
textured plaster;
substrate for laminate, parquet;
waterproofing roll materials;
Styrofoam.

When calculating material consumption, we often (but by no means always!) Start from the area.

When it's not useful

Choosing some types of finishes, you can not even think about how to find out the area of \u200b\u200bthe room. Why? Yes, because we will not make a joint of wallpaper in the middle of the ceiling or assemble a mosaic of linoleum. Based on the area, it is easy to make a mistake when buying, therefore, for roll finishing materials, we need the linear dimensions of the walls - we will count by the number of whole strips. These materials include:

wallpaper;
carpet;
linoleum;
false ceiling type "Armstrong";
stretch ceiling.

Are not an exception floor coverings(laminate, parquet). This value is in most cases informative for small tiles, but it is better to recalculate large tiles based on the length and width of the room.

Wall area

By the same principle that we used when calculating the area of an irregularly shaped room (living room), you can easily calculate the area of \u200b\u200bthe walls. Knowing the length and width of the room, calculate its perimeter, multiply by the height. We get the total surface area, from which we then subtract the areas of windows and doors.

And here is a little trick on how to find out the area of \u200b\u200bthe walls of a room pasted over with standard wallpaper. If you can see the joints between the stripes, count their number. Divide by 2 to get the perimeter in meters. The fact is that the width of the wallpaper roll is just over 50 cm. Therefore, you do not have to walk along the walls with a tape measure before finding out the perimeter of the room.

Knowing the area and linear dimensions of the room, you can easily calculate the amount of materials needed for repairs, even without the help of professionals.

Cabinet area in square meters. required to measure the area. How to calculate the area of ​​\u200b\u200bthe room: the procedure.
