# VIDEO: length and width

## Take the width measurements in a square room

- If your room is rectangular, you can easily determine the length and width of the room. This makes calculating the square meters very easy.
- In order to measure the room as precisely as possible, you should measure it where none furniture stand. If necessary, you should put annoying furniture to one side.
- You need a place where you can measure the width from one wall to the opposite without being disturbed.
- To measure, lay the folding rule on the floor, fully unfolded. Hold it against a wall and mark where it goes. From there, measure again to the opposite wall and add both values for the width together, for example 3.20 m.
- For the length, measure the other side of the room in the same way. Here, for example, you have a value of 4.80 m.
- To calculate the square meters, multiply both values together, i.e. 3.20 m * 4.80 m = 15.36 m².

## Calculate square meters based on several lengths

If your room is not rectangular but has an angle, you will need to repeat the procedure twice.

- Think of the largest possible rectangle in the room and measure it without taking into account the remaining protruding corner of the room. As an example, you have 3 meters for the width and 4 meters for the length.
- To do this, measure the remaining small rectangle that represents the corner of the room, for example 1.20 m by 2 m.
- Multiply the values together, i.e. 3 m * 4 m = 12 m² and also 1.20 m * 2 m = 2.40 m².
- Finally, add the two values together to get the total square footage of your room. So 12 m² + 2.40 m² = 14.40 m². Your room has a floor area of 14.40 m².
