How to calculate the area of \u200b\u200bthe apartment, houses, rooms in square meters to calculate the number of wallpaper: formula, method of calculating and measuring the ceiling, walls, floor. How to calculate the area of \u200b\u200bthe trapezoid, a triangular room in square meters?

In this article, we will consider useful information for builders and people who make repairs. After all, in it we will talk about how to properly measure the room and calculate the number of wallpaper.

Sometimes we need to know what area this or that room has, what is its volume. Such data are necessary during the design of heating and the ventilation system, during the purchase of building materials and so on. Also, from time to time, you need to know what kind of area the walls have. You can easily calculate these data if you work well with a tape measure.

What is the area of \u200b\u200bthe room, what is the formula of the area?

Calculating the area of \u200b\u200bthe room is quite easy. To do this, you need to remember simple formulas, and then make measurements. For work, take:

• Roulette. Better take the roulette that has a lock
• Paper
• Simple pencil
• Calculator

This set is affordable and simple, so you can easily find everything in your home. It is easier to make measurements with an assistant, but you can measure the surface size yourself.

From the very beginning, measure the wall length. Work will not take up much time and time, as it is very simple. But, if there are a lot of heavy furniture in the room, you can measure in the center of the wall. Only in this situation, make sure that the tape is located along the wall, does not move down or up. So the errors will be much less.

The formula, thanks to which you can find out the area of \u200b\u200bthe room, is as follows:

• S (area area) \u003d a x in

In this case, “A” is the length of the room, “B” is the width of the room. The obtained values \u200b\u200bare indicated by “m²”.

How to measure the walls, ceiling for measuring the area of \u200b\u200bthe room?

The floor in the room is not one plane that you will have to calculate. Often, to determine the number of necessary building materials, it is necessary to calculate the size of the walls and ceiling.

Mathematical laws are identical to each two-dimensional figure, therefore, you will not find something new here, if only some points.

Wall

Of course, finding the wall area is very simple - take its length, multiply this indicator by height. But this formula is suitable only for those rooms where the ceiling height is identical at each point of the walls. If we take a room in which there is an attic, then in it the walls will have the shape of a trapezoid or triangle. Therefore, pay special attention at the moment.

Next, follow the following actions:

• Measure the height of the wall
• Measure the width of the wall
• Calculate the area of \u200b\u200bthe wall
• From the resulting number, take the dimensions of the windows and doors in advance (measure the frames and boxes of the doors in advance, make a calculation)

Ceiling

As a rule, with calculating the area of \u200b\u200bthe ceiling, there are never any difficulties. If the ceiling is horizontal, then it is considered an exact projection of the floor.

The rooms that have an attic or an attic are exceptions, since the ceiling and its plane can be at an angle, can be broken, with several tiers and so on. But there is nothing complicated in this. Just “virtually” the surface of the ceiling into several surfaces, and then measure the obtained values.

How to calculate the area of \u200b\u200bsimple room shape, rooms in m²?

A room with a simple shape is the most common and typical option. In order to calculate the area of \u200b\u200bsuch a room, just multiply the length of the room by the width of the room. For example, if the length of the room is 4 m, and the width is 3 m, then 4x3 is required to calculate its area, as a result, 12 square meters are obtained. In order to calculate the parameter of the ceiling of such a room, a completely different formula is used, which implies the following:

• The width is multiplied by 2
• The length is multiplied by 2
• The results obtained are coordinated

In our case, the result is: 2x4 + 2x3 \u003d 8 + 6 \u003d 14. Therefore, when you purchase a profile, you will need 14 m of the material. But, even during accurate calculations, it is worth acquiring materials with some margin, which compensates for various damage and joints.

How to calculate the area of \u200b\u200bcomplex shape of the room, rooms in m²?

In order to determine the area of \u200b\u200ba complex room in which there are niches and various protrusions, you will have to work pretty well and perform such manipulations:

• Draw a project of the premises. At the same time, consider all the design features of the room.
• Calculate the height and length of each wall. Designate the results obtained.
• Take a ruler and a square. Divide the room into some zones so that they have the right figures.
• Measure each side of the figures obtained, designate them on your own project.
• According to a special formula that allows you to calculate the area, determine the dimensions of each figure, fold the results.

Take, for example, a room with a niche. Before calculating the premises, conduct some changes. Only in this case you will receive not 2 digits, but 4 digits. The width of the protrusion is also added to the results, plus the length of the protrusion. Consider the sizes of these pieces separately. For example, your room has the following sizes:

• Width - 4 m
• Length - 8 m

The room has a ledge with the following sizes:

• Width - 1 m
• Length - 3 m

Then come as follows:

• Calculate the area without ledge: 4 m x 8 m \u003d 32 m²
• Calculate the size of the protrusion: 1 m x 3 m \u003d 3 m²

Fold the obtained values: 3 m² + 32 m² \u003d 34 m²

How to calculate the area of \u200b\u200birregular shape of the room, rooms in m²?

If you need to calculate the area of \u200b\u200bthe room, which has the wrong shape, you will also have to divide it into simpler fractions, for example, into squares or rectangles. Next, measure all the necessary surfaces, make calculations according to the formula.

If necessary, calculate the area of \u200b\u200bthe room of irregular shape, use the following tips:

• If the room has a rounded shape, calculate its area using the circle formula: S \u003d πd²/4. In this case, D is the diameter of the round room.
• If you have a terrace that has the shape of a semicircle, then its area will consist of two quantities: the area of \u200b\u200ba rectangle and a semicircle area.

How to calculate the area of \u200b\u200bthe premises in the form of a trapezoid in m²?

The number of square meters of the area of \u200b\u200bthe room, which has the form of a trapezoid, you can calculate with 2 methods.

Method 1

• Divide the room into a square and 2 triangles
• Calculate by the formula for their values
• Fold the received numbers

Method 2

Use the formula s \u003d 1/2 x (a + c) x h, where:

• s is the size of the area of \u200b\u200bthe figure
• a - foundation of the figure
• b - Figure base
• h - figure height

The area of \u200b\u200bthe room that has the form of a trapezoid is half the amount of the values \u200b\u200bof the bases multiplied by the height of the trapezoid.

How to calculate the area of \u200b\u200ba triangular room in square meters?

If the room in which you need to make repairs is not “typical”, that is, it has the shape of a triangle, then you will have to use a more complex formula. You can also divide the room into several rectangular elements and make a counting in the usual way. If you cannot do this, then calculate the area here according to this formula: S \u003d ½ x H x A. Where:

• s is the area of \u200b\u200bthe figure
• h - figure height
• a - side of the figure

Measure to start the height of the triangle. Take the roulette, measure with it the size of the corner to the opposite side. Next, measure the sides of the triangle.

How to calculate the area of \u200b\u200bthe walls: Methodology

If you want to get more accurate results, just calculate the area of \u200b\u200bwindows and doorways from the area of \u200b\u200bthe walls. If you have a room on the walls of which there are protrusions and recesses, then its area will differ significantly. In this case, you will have to add the area of \u200b\u200beach protrusion and recess. Be extremely careful when you make measurements and calculate the calculations.

Have you decided to use a laser roulette? Then do it as follows:

• Take the roulette.
• Install it carefully on a flat surface.
• Direct the beam so that it looks perpendicular to the wall. Otherwise, you will have errors during measurement.

In order to play it safe, measure the area of \u200b\u200bthe wall with a cord. Perform the following manipulations:

• Take the cord.
• Measure with the cord the size of the diagonals
• If you get a slight difference between the standard dimensions and the method obtained by this method, then there will be no critical error during the calculations according to the formula. If the dimensions of the diagonals are very different, then you will need to depict a special scheme.

On the diagram, draw the walls that you measured with a regular roulette. See what figure will be depicted on paper. Does the room have a complex shape? Then, to determine the area, divide the surface into several parts. Calculate the area of \u200b\u200brectangles and triangles separately, and then only add the resulting value.

Believe me, this technique is considered reliable. You will only have to choose the desired formula for counting, find out the data and add up.

How to calculate the area of \u200b\u200bthe ceiling: Methodology

Today it is very fashionable to make suspended ceilings. They can be straight or curved. As a rule, such ceilings are mounted on several levels. In order to determine the area of \u200b\u200bsuch elements, you will also have to break the surface into separate geometric elements.

What kind of tools are needed for work? It all depends on how laborious and accurate the calculation will be. In addition to roulette, you will need to take an elongated rule and a regular square. Break the ceiling, do the work with painting tape. In order to measure the radius, build a homemade compass, using the cord and the sharp pin that you will serve as the center.

So that during work you do not have many errors, carry out each froze 2 times. Keep the roulette always stretched, make sure that it does not sag. If you have a laser range finder, then you will spend a minimum amount of time to work.

Want to facilitate the processing of the results? Then find a calculator on the Internet, which operates online. This service is considered quite convenient, which minimizes manipulations during the calculation of the area.

How to calculate the number of wallpaper on the room in the square?

To date, there are several common and simple methods that allow you to calculate the required number of wallpaper.

• Using the parameter of the room, the number of strips of wallpaper.
• With the help of the entire area of \u200b\u200bthe walls that need to be glued.
• Using online calculator.

Method 1

• Measure the length and width of the room. Determine the overall perimeter.
• Measure the window and door width, subtract from the entire perimeter.
• Divide the resulting value into the width that the wallpaper has.
• Round the result from the larger side, present the required number of strips.
• Divide by the number of strips in one roll.
• The result is rounded to make a whole value - this is the right number of rolls.

Method 2

This method is accurate and most economical. This applies to especially small rooms.

• Calculate the total area of \u200b\u200bthe walls using the parameters of the room.
• Determine the total area of \u200b\u200bwindow and doorways.
• The result is subtracted from the area of \u200b\u200bthe walls. As a result, you get a size that is equal to the area of \u200b\u200bthe walls.
• Calculate the area of \u200b\u200bthe wallpaper in the roll: multiply the width of the roll by the length of the roll.
• Divide the total area of \u200b\u200bthe walls into the area of \u200b\u200bone roll.
• Prut the result to the result so that you get a round number. Next, increase the number in the most way - this result will show you the number of wallpaper necessary for gluing.

Both 1 and 2 options are almost identical. But in the 2nd case, the total area of \u200b\u200bthe room that you plan to glue is taken into account. Therefore, in this version, you should not purchase another 1 roll as a spare material.

Method 3

This method is considered simpler, since the calculations for you will be made by an online calculator. Today on the Internet you can find a huge number of sites that allow you to use such an online calculator absolutely free.
