How to measure your room for carpets and sheet vinyl

As carpets and sheet vinyl only usually come in set widths, measuring a room for them differs slightly to measuring for a hard floor in that you only need to take two measurements – the longest length and the widest width.

Measuring a square or rectangular room

First, measure the width of your room, including any alcoves, door recesses, or bay windows (size A).

Carpets are usually sold in set widths so, if your space is between sizes, you’ll need to opt for the larger. Any extra carpet is known as an offcut.

Then, take the measurement of the length of your room, again including any alcoves, door recesses, or bay windows (size B).

Carpets can usually be cut to any length required but always add an extra 10% to any measurement to allow for deviations in the wall and the cutting of your carpet when fitted.

Measuring an odd shaped room

First, measure the width of your room, including any alcoves, door recesses, or bay windows (size A).

If you have an oddly shaped room, you will need to take the widest width and the longest length measurements to calculate the carpet you need.

If your room is L-shaped, for example, the area highlighted (C) will be wastage.
