It's important to measure up carefully. To make sure you order enough flooring, you should measure the maximum width and length of the room including any recess or doorway. Put those dimensions into our calculator and it will then work out how much you need. If you have an irregular-shaped room, or want to keep wastage to an absolute minimum, though, we recommend you draw a floor plan and calculate for yourself. Bear in mind that the amount you need has to be a multiple of the width of the roll and so it won’t necessarily be the same as the area of your room.
