Flooring quantity formula
Room area = length × width. Required area = room area × (1 + waste percentage). Packs = required area ÷ pack coverage, rounded up.
Planning notes
Use the exact coverage printed on the flooring pack. Irregular rooms can be split into rectangles and added together; patterned installations often need more waste.
- Check the exact pack coverage printed by the manufacturer.
- Patterned layouts may need a larger waste allowance.
