The **living space** or **room area** of an apartment or house is calculated using the area calculation. The formula for the area of a quadrangle (rectangle or square) is usually used for this: **A = a * b**. The square meters are given in **m²**.

## Calculator

**Calculation**: Length (l) * Width (b) = Surface area^{2}

## Table

Length | Width | |
---|---|---|

5m | 3m | 15m^{2} |

4m | 4m | 16m^{2} |

7m | 5m | 35m^{2} |

10m | 4m | 40m^{2} |

8m | 6m | 48m^{2} |

- Enter the width of the living space in meters (m).
- Click on "generate" to get the result.

## How do I calculate the living space in square meters?

You can do this in the following steps:

- First, you need to measure all the rooms in the property and add up the areas. In most cases, the walls are already plastered and individual rooms can no longer be subdivided by partition walls. However, this is not a problem - only the total area counts for the calculation process, i.e. the total living space without deducting intermediate rooms or stairwells.
- Now you need to convert the measured areas to square meters. To do this, use a tape measure to determine the length and width of the room and multiply the two figures together. The following formula applies for the conversion: L*B=QM (L stands for length and B for width).
- Now add up all the square meters of the individual rooms to find the total living space in square meters. Be particularly thorough here, as living space is one of the most important criteria when buying or renting a property.

With this method, you have now determined your living space in square meters and can make further calculations based on this data, such as calculating the purchase price or price per square meter. This gives you an overview of the current market value of your property and allows you to make more targeted decisions.
