If you are going to make repairs in the toilet with your own hands and use tiles at the same time, you will need to solve many important issues. First of all, it will be necessary to decide on the type and design of the coating, and then correctly. This stage should be taken with all responsibility so as not to end up with unfinished walls and not spend extra money on unnecessary material.

Before starting repairs, it is necessary to decide on the design of the room and calculate the necessary materials.

Preparation for calculation

• roulette;
• calculator;
• pen and paper.

Take a tape measure and measure the width and length of the toilet. Add up the values ​​obtained and multiply the sum by 2. All measurements must be taken in meters. For example, you need to calculate the tiles for a toilet with a length of 2 m and a width of 1.5 m. Using the above formula, you will determine that in this case the perimeter of the room will be 7 m.

Such a simple calculation of toilet tiles also allows you to determine the required number of friezes and borders, if their use is provided for by the design project you have chosen. To do this, translate the previously calculated perimeter of the toilet into centimeters and divide by the length of one curb. The resulting value is the number of borders that will need to be purchased for cladding. Add a few spares.

In practice, it looks like this. As an example, the same toilet with a perimeter of 7 m is considered, i.e. 700 cm. Subtract the width of the door from this perimeter (usually about 80 cm), and you will get a value equal to 620 cm. .e. 25 pieces.

When performing a calculation, always round to the nearest whole number.

Otherwise, you simply do not have enough of one product.

Instructions for calculating floor tiles

To accurately calculate the number of tiles needed, you need to divide the floor area by the area of ​​\u200b\u200bone tile.

Now you need to calculate the tiles for finishing the floor. It's very simple. All you need to do is calculate the surface area. To do this, take a tape measure and measure the width and length of the floor. In this example, the surface area will be 2x1.5=3 m². Thus, you will need to purchase an amount of facing material that would be enough to cover 3 m² of surface. Usually finishing material is sold in packages, each of which is enough to decorate 1 m², so it will not be difficult for you.

Experts say that piece-by-piece calculation of tiles is more accurate. To perform such a calculation, you first need to determine the area of ​​\u200b\u200bone product. For example, if you are going to use a square tile with a side of 50 cm for finishing the floor, then the area of ​​\u200b\u200bone such product will be 0.25 m². Thus, for a floor covering of 3 m², you will need to buy 3 / 0.25 = 12 tiles. Buy 3-4 pieces more for cutting, possible damage during operation, etc.

The number of tiles for lining the walls of the toilet should be bought 10-15% more.

The calculation of tiles for wall cladding is also quite simple and understandable. It is most easily performed if the walls of the bathroom are lined with material of the same color and the same size. In this case, you will need to find out the total area of ​​\u200b\u200bthe room. To do this, multiply the previously calculated perimeter by the height of the bathroom, and then subtract the area of ​​​​the doorway from it. In this example, the perimeter of the toilet is 7 m. The ceiling is 2.5 m high. A door 80 cm wide and 2 m high was installed. As a result, the total area of ​​​​the room will be: 7x2.5 - 2x0.8 \u003d 15.9 m².

After that, you will need to determine the area of ​​​​one ceramic product. In this example, 60x30 cm tiles will be used for wall cladding. Thus, the area of ​​\u200b\u200bone product is 0.18 m². To determine the required amount of material for cladding, you need to take the total area of ​​\u200b\u200bthe room and divide it by the area of ​​\u200b\u200b1 product. In this example, you will need to use: 15.9 / 0.18 = 88.3 tiles. That is, you will have to purchase 89 pieces.

To all these values, be sure to add about 10-15% in reserve. If you lay the cladding in a direct way, then buy 10% more material. If the lining is carried out diagonally or by other complex methods, the calculated value should be increased by 15%.

How to calculate the area of ​​​​a room in square meters: instructions for measuring a living room, bathroom, kitchen, balcony and garage

In order to save on building materials, you need to know the exact footage of the dwelling.

To do this, you need to be able to correctly measure the room.

This article details how to do this.

Where to start measuring

Each room has 3 indicators to measure:

1. Length. Most often there are values ​​\u200b\u200bof 4 or 4.5 meters.
2. Width. In a standard apartment building, the width of the rooms is 3 or 3.5 meters.
3. Height. In new buildings, the height of the walls is 2.5 meters, and for example, in buildings of the Stalin era, it can reach three meters.

To measure square meters, you will need the following tools:

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

Algorithm for calculating the quadrature of the room

For the calculation, it is necessary to apply the area formula: S \u003d a * b, where S is the area, a is the length, b is the width.

So, let's calculate the footage using the example of a living room with the following indicators:

Height (h) = 2.5 m;

Width = 3 m;

Length =5 m.

Let's calculate the floor area of ​​the room: S= 5 m*3 m = 15 m2. You will need these data when buying a floor covering or installing a stretch ceiling.

We calculate the area of ​​\u200b\u200bthe room along the walls using the following formula:h *(a*2+ b*2).

We calculate as follows: 2.5 m * (5 m * 2 + 3 m * 2) \u003d 40 m2.

In order to obtain net area values, it is necessary to subtract the area of ​​doors and windows from 40m2.

Doors and window openings

Standard doors have the following dimensions:

Width = 0.8 m, height = 2.0 m.

We multiply the indicators on each other: S \u003d 0.8 m * 2.0 m \u003d 1.6 m2.

A standard window in a multi-storey building has the following dimensions:

Width \u003d 1.6 m, height \u003d 1.5 m. In the course of the product of two numbers, we get the area: S \u003d 1.6 m * 1.5 m \u003d 2.4 m2.

Snet \u003d 40 m-2.4 m-1.6 m \u003d 36 m2.

Master's note: determining the net area will help you choose the right amount of wallpaper tubes, drywall sheets and other finishing materials.

Irregular room

It is necessary to measure the quadrature of the room in stages, dividing it into several sections of the correct shape.

So, let's look at concrete examples of how to calculate the footage:

1. Kitchen. Each kitchen has a ventilation shaft, a radiator along the window, a door, a window and a built-in storage shelf. Let's calculate the net area of ​​\u200b\u200bthe walls of the kitchen for.

Kitchen details:

Height =2.5 m;

Width=3m;

Length =3.5m.

Door size: width=0.8m, height=2.0m;

Window size: width 1.2 m, height = 1.5 m;

The ventilation shaft has the following dimensions: width =50 cm, length =30 cm; height = 2.5 m;

Built-in shelf: width = 20 cm, length = 50 cm, height = 2.5 m;

Radiator dimensions: width = 10 cm, length = 100 cm, height = 50 cm.

Let's calculate the net area:

First, we find the total area: (3.5 m * 2) + (3 m * 2) * 2.5 m = 32.5 m2;

Windows: S net = 1.2 m * 1.5 m = 1.8 m2;

Doors: S net = 0.8 m * 2.0 m = 1.6 m2;

Ventilation shaft: S net = (50 cm * 2) + (30 cm * 2) * 2.5 m = 400 cm2 or 0.40 m2;

Built-in shelf: S net = (20 cm * 2) + (50 cm * 2) * 2.5 m = 350 cm2 or 0.35 m2;

Radiator surface area: (10 cm *2) + (100 cm *2) * 0.5 m = 110 cm2 or 0.11 m2.

Now we determine the number of net square meters by subtracting their total area: S net kitchen walls \u003d 32.5 m2 - 1.8 m2 - 1.6 m2 - 0.40 m2 - 0.35 m2 - 0.11 m2 \u003d 28, 24 m2.

Useful advice: to count the number of wallpaper tubes, you need to divide the net area by the number of sheets in the tube.

A standard tube has the following dimensions: width = 50 cm, web length = 10 m. The height of the walls of the apartment is 2.5 m, and it follows that 4 paper sheets are included in one tube: 10 m / 2.5 m = 4 sheets.

Let's calculate how many tubes are needed to:

28.24 m2 / 4 = 7.06 tubes. But since a paper canvas can contain a pattern in increments of 0.3 or 0.5, the number of tubes should be rounded up to 8.

1. Bathroom. Calculate the number of boxes of tiles for a standard bath. In order to correctly calculate the quadrature of the room, it is necessary to take measurements taking into account the trimming of ceramic tiles.

We know the standard size of the door: width = 0.8 m; height = 2.0 m.

The size of a typical bathroom is: width 2.3 m; length = 1.6 m, height = 2.5 m.

We calculate the net area of ​​the bath:

S baths \u003d (2.3 m * 2) + (1.6 m * 2) * 2.5 m \u003d 19.5 m2.

Then, subtract the following values:

S net = 19.5 m2 - 1.6 m2 = 17.9 m2.

In order to calculate how many boxes of tiles you need, you should decide on the size of the ceramic product. The tile comes in the following sizes: 10x10; 10x20; 20x30; 30x30. Let's take a more common option: 30x30.

There are 10 pieces in one package and, knowing the size of the tile, you can calculate the number of pieces per 1 m2:

1 m2 is 100 cm by 100 cm, it follows that 1 m2 includes 9 whole tiles 30x30 and 7 tiles, 10x10 cm in size.

Let's determine the number of whole tiles and the number of cuts:

17.9 m2 / 9 \u003d 1.9 - round up and get 20 boxes of whole tiles;

20 * 7 = 140 small tiles, 10x10 in size.

If you lay tiles on a plane without trimming, then you should take 20 boxes, and if with trimming, then 16.

1. Balcony. To get the net area of ​​the balcony, it is necessary to measure the frames with glazing. The perimeter of the balcony is measured excluding windows.
2. Garage. As a rule, the garage is a box with a small window. To calculate the net area, it is necessary to measure the dimensions of the gate.

try on the area of ​​​​a round window, ceiling, building wall in the form of an irregular shape or an octahedron, you can use improvised means.

Take a tape measure and measure the maximum diameter of the circle, for example, it turned out to be 100 cm. We calculate the radius: 100 cm / 2 \u003d 50 cm - this is ¼ of a circle in the form of a triangle.

If the circle is visually divided into 4 parts, and the points are connected with straight lines, we get 2 isosceles triangles or 1 square. We know a part of an isosceles triangle, therefore, all sides will be 50 cm long. It remains to find the area of ​​a square where all sides are 50 cm long. You can calculate the total area of ​​\u200b\u200bany structure using an online program.

Let's say that you want to start doing repairs in your own apartment. To do this, you should decide on the amount of materials needed and the amount of money that will be spent on them. So, the budget for repairs is directly related to the quadrature, i.e. with the floor area measured in square meters. Today we will figure out how to calculate the area of ​​\u200b\u200byour (or any other) room or even an entire apartment. Consider some aspects and nuances.

How to calculate the square of a room

Now let's take a closer look at how the area is calculated. It is worth considering that the shape of the room is not only rectangular. There are other cases, in each of them the calculation is done differently. Let's look at various examples.

What do you need to calculate

In order to quickly calculate the required area, you will need:

• Roulette (with or without lock);
• Paper where you will write everything down, a pencil and a pen;
• Calculator for calculations, but you can do it in your mind and in a column on paper.

All this set is available in almost any home. It is better to take measurements with someone. It will be more convenient, but you can also do it yourself.

The first step is to take the measurement of the walls. This is done along them. You can also measure in the middle if they are filled with furniture.

3 by 3 how many square meters

To calculate a room 3 by 3 square meters, there is a fairly simple formula, you just need to multiply the measured length by the width. That is, we take 3 and multiply it by 3 and it turns out that a room 3 by 3 meters is 9 m².

3 by 4

Here it is calculated in the same way as in the previous formula. We take and multiply two values ​​\u200b\u200bof 3 * 4 and get 12 square meters.

3 by 6 how much will it be m²

And there is nothing new here. Again we take two values ​​- 3 and 6, and then multiply them. The result is 18 m².

Rectangular room

If the shape of the room is correct, which is very convenient, and there are no protruding parts, you can easily measure the area of ​​\u200b\u200bthe room.

Take a tape measure and use it to measure the length and width of the room. Write down the values ​​​​obtained on a piece of paper, so as not to forget. Record the value in meters. Then these figures should be multiplied, and you get the area of ​​\u200b\u200bthe room in square meters. By the way, it is desirable to leave two digits after the decimal point, so if anything, you need to round.

Wrong room shape

Sometimes in apartments, and most often in private houses, there are rooms that differ from a rectangular shape.

To measure the square of a room that is not rectangular or square, you will have to divide it into various shapes such as rectangles, triangles, and so on.

• If you need to calculate the area of ​​​​a room in the form of a circle, you should use the formula S \u003d D2 / 4, where D is the diameter of the room.
• The area of ​​a triangular section is calculated according to the Heron formula S \u003d √ (P / 2 (P / 2 -A) x (P / 2 - B) x (P / 2 - C)), where the letters A, B, C mean its sides , and P is the perimeter, respectively.
• To calculate the area of ​​​​the terrace, if you have a private house, you need to sum the area of ​​\u200b\u200bthe rectangle and the semicircle.
• In the case when a segment should be calculated, the formula R2 / 2 (/ 180 - sin) is used. This is a rather complicated calculation. The letter "a" refers to the angle of the segment, which is expressed in degrees.

How to calculate the square of a wall

The calculation of the area of ​​​​the walls is necessary when you are purchasing materials - wallpaper, plaster, and so on. In this case, in order to calculate the square of the wall, additional measurements will be needed, for example, how high is the ceiling.

Wall, excluding windows, doors

Calculate the square of the walls easy, since the simplest formula is used - the length of the wall is multiplied by the height. Let's say the height is 2.7 meters, and the width is 7 meters, then S = 7 * 2.7 = 18.9 m2. This is the area of ​​the walls.

How to calculate the square of the floor

In this case, it all depends on what the geometry of the room is. If the room is of the correct shape, then in order to find out the floor area, you should measure the length or width of the rectangle, square. Square meters are calculated using the formula S = H*B. Where "H" means the length of the room, and "B" the width. If the room is square, just square the length of the side.

Floor without stove, fireplace

To do this, these elements should be excluded from the total area, that is, before calculating the total area, you need to know the square meters of a particular object:

1. We consider what square you have.
2. Then you should calculate the quadrature of the area where the stove or fireplace is located.
3. Now from the total area you need to subtract the one that touches the stove or fireplace.

Room volume

In some cases, you need to calculate the volume of the room. This is not difficult, you just need to multiply three values: width, length, height. This value is measured in cubic meters and is also called cubature. That is, the same formula as with the calculation of the area of ​​​​the room, only the third value is added, and that's it.

Conclusion

Now you have received the answer to the question of how the area of ​​\u200b\u200bany room is calculated. Even if it is complex, then it's okay, you need to break it into simple shapes. You can also use the online calculator needed to calculate the square footage of the room. It can be of great help in some cases. By the way, always keep 5-10% of materials in stock, as there may be errors in the calculation.

The same online calculators may also not work correctly. The best way to calculate everything is to do it yourself.

It is easy to check the work of builders, determine the amount of work and materials, knowing how to calculate the square meters of the floor or walls of a room using simple geometric formulas, simple calculations and simple tricks.

called a square meter area unit, adopted in the international system of units, SI. 1m² is equal to the area of ​​a square with a side of 1m.

Knowing simple rules and several geometric formulas for calculating the number of square meters of walls, floors, ceilings will allow you to avoid errors in calculations and correctly determine the required values.

Counting tools

For measurement and calculation, you will need the following objects and tools:

• measuring tape, the required tape measure length is 3-5 m;
• pencil;
• sheet of paper for notes;
• calculator;
• construction corner.

Square mark perpendiculars - lines intersecting at right angles.

Room area

Knowing the footage of the room is useful to determine the cost of flooring, ceiling finishes, the number and power of lighting fixtures. Measuring the quadrature of the room, check the conformity of the area declared for the project.

It is more convenient to measure walls from below, at the level of the plinth. Doubts about the correct form of the room are eliminated by measuring the diagonals. If the diagonals of the room are equal, then the corners are right, and the room is rectangular.

Square or rectangle

The most common form of a room in terms of - square or rectangular. Calculating the square on the floor in this case will not be difficult:

• measure the length and width of the room with a tape measure;
• multiply the numbers among themselves, writing the result on paper;
• protrusions, columns are measured, the area of ​​\u200b\u200belements is calculated according to the same principles, multiplying two sizes;
• the resulting numbers are subtracted from the area of ​​​​the room.

At the same time, the area of ​​\u200b\u200bthe ceiling is calculated according to the same principle, that is, the length is multiplied by the width minus technological openings, if any.

By counting the square meters of the premises and adding them up, you can find out the area of ​​\u200b\u200bthe entire house.

Irregular room

Bay windows, attics and rooms of houses with complex architecture in terms of often irregular in shape. The footage of a non-standard room with semicircles, ledges, and many corners is more difficult to calculate. Facilitate the task by using principle of dividing complex figures into simple ones.

The floor, representing as a composite figure mentally or displaying on paper, is divided into standard geometric elements. Then calculate the area of ​​the elements one by one and add the resulting values.

L-shaped, T-shaped rooms in terms of break into rectangles and squares. Semicircular surfaces are taken as part of a circle.

The number of square meters of the floor of a room based on a trapezoid can be calculated in two ways:

• imagining a trapezoid combination of a square with two triangles. Having received the value of the figures, the numbers are added;
• on formula trapezium area.

To calculate by the formula, two opposite long walls are measured, these dimensions will give the values ​​\u200b\u200bof the bases. The height value is determined by measuring the perpendicular drawn from one of the corners of the smaller base to the larger one.

Trapezoid area formula S=1/2(A+B)*H, where:

• S is the desired value, the area of ​​the trapezoid;
• A - the base of the trapezoid;
• B - the base of the trapezoid;
• H is the height of the trapezoid.

The area of ​​a trapezoidal room is half the sum of the numerical values ​​of the bases multiplied by the height.

Room volume

The cubic capacity of the room, or the volume in construction, is used when calculating the required power of heating, ventilation, and air conditioning of the room.

Volume is measured in cubic meters. The unit is written as 1 m³.

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

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

The volume of a room of a complex shape is calculated as follows:

• the floor of the room is divided into simple geometric shapes;
• calculate the quadrature of each figure;
• the resulting values ​​\u200b\u200bare added and multiplied by the height to the ceiling.

How to calculate the square of the walls?

The size of the wall in square meters is needed to count the number of finishing materials, the placement of shelves, mirrors or wall cabinets.

solid wall

The square of the wall is calculated similarly to the floor area - length, height of the wall after measurement are multiplied between themselves. All depressions and protrusions, if any, are taken into account. The walls of attic rooms under the roof are often broken in shape, the segments are in different planes.

In this case, sections of the wall are measured separately, transferred to paper. Calculate the area of ​​each individual geometric figure and summarize the numbers.

with window

Determining the number of square meters of the wall, window openings, as a rule, exclude.

The end faces of the walls near the window are called slopes, their dimensions are also not included in the footage of the wall and are considered separately, for example, when calculating plastering or puttying.

with door

Quadrature of the doorway from the area of ​​the wall when calculating subtract. Slopes, if necessary, are measured separately.

We measure the area of ​​\u200b\u200ba irregular shape

When calculating the footage of decorative arched openings or lancet windows, they follow the same principle, breaking a complex figure into a few simple elements.

Parts of a circle and triangles are combined with squares and rectangles.

Circle

A whole circle in the interior is quite rare. A window, columns, the central part of a multi-level ceiling can be completely round. Basically, you have to deal with parts of the circle: half or segments.

Measure with a tape measure between two opposite points of the circle. This segment will be called diameter. The radius of a circle is half the diameter.

The area of ​​a circle is calculated using the formula S = π*R², where:

• R is the radius;
• S is the area of ​​the circle;
• π is a constant mathematical value, rounded up to a value of 3.14.

The numerical value of the area of ​​the semicircle is obtained by dividing the result by 2.

The quadrature of a sector of a circle is equal to the product of half the length of the arc of the sector and the radius of the circle, calculated by the formula S=1/2L*R.

Triangle

Triangle area formula S=1/2*H*A, where:

• S is the area of ​​the triangle;
• H - height;
• A is the side of the triangle.

The height of a triangle is obtained by measuring the perpendicular from the angle opposite to the side with a tape measure.
