### rectangular room

This is the most common and easiest per case.

The area is calculated by simply multiplying the length by the width of the room. For example, the size of 2,4h3,8 meter room will have an area **2.4 * 3.8 = 9.12 (square meter).**

How to calculate the perimeter of the ceiling in this case? It is also easier than ever: it is equal to the sum of twice the length and twice the width. **2.4 * 2 + 3.8 * 2 = 12.4 m.**

Of course, when purchasing profile to round its total length to a multiple of the size of a single strap. That is, if there is only on sale **UD profile 2 meters long**, you will have to purchase 14 linear meters, or 7 bars.

Tip: Of course, the closer to the ceiling surface you measured the size, the more accurate values were obtained. The walls are often inundated; this is especially true for stalinok with wooden partitions.

Finally - one more tip. In most cases 3-5% error in the calculation area of the room is not critical. Slight curvature of the walls or the rounded corners can simply be ignored.

# How to calculate the area of any ceiling

During repairs, at the stage of finishing the ceiling should make some measurements. If repair work is done by a team, its employees take on this task. However, this procedure is no different high complexity. This article will help you understand how to calculate the ceiling area, whatever form it may have.

Always, you can easily make your own calculations

To make all the measurements correctly, you need very little - to play in the memory of the elementary rules of geometry and find simple tools.

- Roulette (the easiest to work with a laser tape measure, but in the absence of such, it is possible to do normal);
- ladder;
- building level;
- pencil, pen or marker;
- paper;
- calculator.

## We determine the shape of the room

The complexity of the measurement will depend on what form the room. She may be:

## Calculations: A sequence of actions

This is the most easy case, since the area of the ceiling and floor will be the same. Because of this you will not have to use a ladder to make the necessary measurements.

Measure the space length and its width. Then, using a simple formula **S = A * B**, count on the calculator area. A - length B - width.

Example: House length = 6 m, width = 3 m 3 * 6 = 18 m 2..

Often the room is L-shaped or U-shaped. The above formula is quite possible to apply in this case. The room is divided visually into rectangles and then calculated squaring each of them. Then, the results are added.

Example: room 6 m long and 3 m wide process there, which length is 2 m and a width of 1 m.

6 * 3 = 18. 2 * 1 = 2. 18 + 2 = 20 m 2

### For premises of irregular shape

At the premises it is often irregular shape due to existing benches, columns and so on. N. If you need to measure the area of the ceiling in a room, it should be done in two stages. You should first calculate the perimeter.

Using a tape measure, measure all the walls and record their results. After that, draw a sketch of the room. Furthermore it will depend on the shape. If the room has benches, and determine the value of each of them. To do so, the height must be multiplied by the length. This squaring added to the total area.

Example: House length = 6 m, width = 3 m 3 * 6 = 18 m 2.. protrusion length = 1 m, width = 0.5 m Number of protrusions -. three. Square protrusions: 3 * (1 * 0.5) = 1.5 m 2. 18 + 1.5 = 19.5 m 2.

If the room is trapezoidal, used a slightly different formula - ½ * (A + B) * H. H is the height that is the distance between the parallel sides, and A and B - parallel sides.

Example. One side of m = 3, m = 5 second height H = 4 m ½ * (3 + 5) * 4 = 15 m 2..

The plane of the ceiling can be slanted. In this case, performing calculations, it is necessary to measure the other hand, the length of which is identical to the ceiling and floor. Thereafter measured length downhill. The results are multiplied.

Example: length = 3 m = 4 m sloping 3 * 4 = 12 m 2..

Counting room area of any irregular use of crushing principle. He is as follows:

- sketch is divided into regular geometric shapes (rectangles, squares, triangles);
- squaring each calculated area;
- the results are summarized.

The easiest way to measure each site separately

The more accurate the calculations will be made, the better. But do not be a perfectionist: the error can not be avoided. If it is not more than 5%, do not worry - great value it has.

## Why the ceiling area is calculated?

Now, when we figured out how to calculate the ceiling area, it must be said, why is it important to do. It is necessary to understand what will be the cost of the repair work.

## When repairing your own hands

Calculate the exact area of the ceiling, you'll see how much material you will need for his finish. Remember that in any case the finishing materials must be purchased with a certain margin. It should be about 15%.

All materials should be acquired with a margin

Most of the maintenance teams in the price lists indicate how many services are finishing one square meter. Knowing what area of the ceiling, you can easily calculate how much it will cost repairs. This will avoid confusion when calculating the mass of workers.

When planning the budget on the ceiling repair cost estimate to make very important. It is in this and help simple geometric calculations. Do not neglect the counting - they will help to minimize the monetary costs, but also save your valuable time.

During repair work often have to solve a variety of issues. It is necessary to select materials, design projects and perform a number of other equally important activities. One of them is the original calculation of the required amount of material. Many jobs require simultaneous implementation, it is important that all you need was available. In turn, the calculation of the material is not possible without knowledge of the scope of work. In the case of ceiling mounting cover holding calculation requires knowledge of surface area supposed to finish. Below we will talk about how to calculate the ceiling area.

Despite the fact that at first glance, the issue of the calculation of the ceiling area is no big deal, some difficulties may arise.

One of the most simple cases - this when the room has a simple rectangular shape. If so, then you just need to measure the length and width of the room floor. In order to calculate the area, multiply these two values. Since most of the floor and ceiling are the same size, then get rid of the need to use a ladder and measure the ceiling, all the necessary actions can be performed on the floor.

The above example is the most simple one, but often find examples, when the room has a somewhat more complex shape, for example, has a column structure or ceiling has projections or elevation. In these cases, the calculations are more complex and in several stages. First, you need the previous case to calculate the total area of the ceiling of the room, and then you need to carefully fathom all projections ceiling heights and swings his area and columns add up the values. Then you need from the first value minus the sum of the second and the result will be the desired area of the ceiling surface.

Options calculation of complex shape areas:

Another embodiment is a room with a sloped ceiling. In this case, proceed as follows:

- First there is a side dimension perpendicular to the slope.
- Then the length is measured sides inclined plane.

Most often, such ceiling is encountered when used as a residential attic space, which means that the height is unlikely to be too large.

Another embodiment, which may be encountered when carrying out measurement ceiling area is trapezoidal space. In order to calculate the area of the ceiling, it is necessary to apply the principle of the crushing area. Its essence lies in the fact that if the room has a flat ceiling surface, but geometrically it has a complex shape, such as is now seen, it is necessary to divide the total area into multiple pieces that have the right shape and calculate the area of each of them separately, and then put them together receiving the required total area. You can also use a simple formula area of a trapezoid, by measuring the length of the parallel sides and the height of the trapezoid.

Finally, you can add that often the question of measurement of the ceiling area - a fairly simple task for self-realization. But it is not necessary to treat without proper attention to it.

Note! Correct the calculations are the key to quality results and in many ways makes them easier to hold.

To simplify the measurements can be used lasers. The tool is not cheap, but it greatly simplifies the collection of measurements.
