The Education Centre: How to Measure a Room?

To calculate the total cost of your new floor, the first thing you will need to do is calculate the size of your room. To do this you must work out the area of the room in m2.

This is simple enough to do. Rectangular rooms can be calculated easily by multiplying the length by the width (see example 1). Don’t worry if your room isn’t a standard shape, we can work this out by splitting the room out into sections. If your room is L-shaped, has alcoves or bay windows all you need to do is divide your room into separate rectangles. Once you’ve done that, simply add the values of the rectangles together to reach your total room dimensions. (see examples 2 and 3).

Don’t forget to add at least 10% to your finally quantity for any wastage that comes from trimming and working around features. The easiest way to do this is to multiply the m2 area of your room by 1.10 to get the final total including wastage.
