# How to calculate square meters of walls, floors, rooms, apartments?

It is the general explanation of calculating square meters. If you want to know about the Square footage measurements, then you can easily convert it by using Square Footage Calculator.

Carrying out construction or repair work always requires preliminary calculations. You need to know how many square meters in the room; square meters of walls, ceiling, floor is calculated separately. The amount of material that should be purchased will depend on this. Next, we describe how to calculate square meters of walls, ceiling, rooms, apartments.

## Why count?

The need for an accurate calculation of the area of ​​a room or apartment may arise during the sale or repair. In the first case, the price of the apartment/share depends on this, and in the second – the number of building materials needed for repair. During the repair, square meters are important for all types of floor replacement work, such as screed installation; thermal insulation; parquet replacement; installation of underfloor heating or liquid linoleum. The exact size of the room is important when redeveloping an apartment to decide, as well as when buying or ordering furniture so that all selected interior items fit into the room.

## How to calculate square meters?

First, carefully look at the room. The room consists of a ceiling, walls, floor; it has a window and doorways. You need to calculate the area of ​​all surfaces that will be subject to repair work, considering windows and doors. We will describe further actions in steps:

## Choosing a Measurement Tool

Take a tape measure or a measuring tape with the marks on it in centimeters or meters. This tool will facilitate the calculation of the area in square meters. To conduct measuring work, specialists use special laser roulettes, with which you can quickly calculate angular and linear values. If your roulette uses not meters, but other units, for example, feet or inches, then after measurements, convert the indicators into square meters.

## Length measurements

Measure the length of the surface from one angle to another and write down the result. If the length is more than 1 m, then count it both in meters and in centimeters. For example, 3 m 45 cm. If the surface is long, measure the length in stages. Stretch the tape measure and make a mark at the very end, then stretch again and start from the marked area. Repeat the steps until you measure the entire length. Then add all recorded indicators.

## Width measurement

Measure the width by positioning the tape measure at an angle of 90º with respect to the length of the surface. Record the obtained values ​​as well. Round off towards the nearest centimeter. For example, if the width is a little more than 1 m 10 cm, then write down this figure excluding millimeters.

## How to calculate the area of ​​a room in square footage calculator?

According to the rules of mathematics, the area is measured by multiplying the length by the width. Performing this action, you will get the area of ​​the measured object. Use a square footage calculator to do this.
