How to work out the area of a room

Measure the length and width. Measure each wall to wall. For an L-shaped room, split it into two rectangles and add both.
Pick your units. Metres, centimetres, feet or inches. Results always show in both m² and ft².
Add extra for cutting. For flooring or tiles, add about 10% so you have enough after cuts.
See the cost. Type the price per square metre to see the total.
