How many m² of flooring to order?

Measure, add the right margin, convert to boxes: the three-step method to order the right amount, in one go.

1. Measure every room

Measure the length and width of each room, wall to wall, and multiply them. For an L-shaped room or one with an alcove, split it into rectangles and add up their areas. Do not subtract small items such as a radiator or a pillar: the cutting margin covers them.

2. Add a margin for cutting losses

Some planks are always cut at the end of rows, around doors and along walls. Allow:

  • 10% for a standard straight installation (5% is enough for a very simple room);
  • 10 to 15% for herringbone;
  • a little more for a complex room: alcoves, columns, many doors.

3. Convert to boxes

Divide the surface, margin included, by the surface of one box and round up to the next whole number. Example: a 4 × 5 m room is 20 m². With a 10% margin you need 22 m². With a vinyl floor of 2.579 m² per box: 22 ÷ 2.579 = 8.53, so 9 boxes (23.21 m²).
