How to calculate the ceiling area

When carrying out repair work often have to solve a variety of issues. It is necessary to choose materials, draw up projects and perform many other equally important actions. One of them is the initial calculation of the required amount of material. Many types of work require simultaneous execution, so it is important that everything that is needed is available. In turn, the calculation of the material is impossible without knowledge of the scope of work. In the case of ceiling installation, calculations require knowledge of the surface area to be finished. Below we will talk about how to calculate the area of ​​the ceiling.

Calculation options

Despite the fact that at first glance there is nothing difficult in the question of calculating the ceiling area, certain difficulties may arise.


Calculation of the square of the rectangular ceiling

One of the simplest cases is when a room has a simple rectangular shape. If so, then you just need to measure the length and width of the floor of the room. In order to calculate the area, you need to multiply these two values. Since the dimensions of the floor and ceiling most often coincide, in order to get rid of the need to use a step ladder and measure the ceiling, all the necessary actions can be carried out on the floor.

Complex forms

The above example is the simplest option, but you can often find examples when the room has a slightly more complex shape, for example, it has a column in the design, or the ceiling has projections or height differences. In these cases, the calculations are carried out somewhat more difficult and in several stages. First, it is necessary, similarly to the previous case, to calculate the total area of ​​the ceiling of the room, and then you need to carefully measure all the projections of the ceiling, the differences in its heights and the area of ​​the columns, and add these values. Then you need to subtract the sum of the second from the first value and the result will be the desired surface area of ​​the ceiling.

Calculation options площади сложной формы:

Difficult form with right angles Crushing on the area of ​​a rectangle and a triangle Area of ​​a right triangle Complex form with additional elements that are not included in the calculation

Inclined plane

Another option is a room with a sloping ceiling. In this case, you should do this:

  • First, measure the side perpendicular to the slope.
  • The length of the side of the inclined plane is then measured.

Most often, such a ceiling is found when an attic is used as a dwelling, which means that the height is unlikely to be too large.


Formula trapezium area

Another option that you may encounter when measuring the ceiling area is the trapezoidal shape of the room. In order to calculate the area of ​​such a ceiling, it is necessary to apply the principle of crushing the area. Its essence lies in the fact that if the room has a smooth surface of the ceiling, but geometrically it has a complex shape, like now under consideration, you need to split the total area into several shapes that have the correct shape and calculate the area of ​​each of them separately, and then add them together by getting the desired total area. You can use the simple formula for the area of ​​a trapezium, measuring the lengths of parallel sides and the height of the trapezium.

In conclusion, we can add that most often the issue of measuring the ceiling area is a fairly simple task for independent implementation. But at the same time to treat without due attention to it is not worth it.

Note! Correctly carried out calculations are the key to a quality result of work and in many respects simplify their implementation.

To simplify the measurement, you can use laser levels. The tool is not cheap, but it simplifies measurement as much as possible.
