How to use this calculator
- Enter the room length and width.
- Add a waste percentage and the coverage of one pack.
- Read the area and packs needed.
How it works
Area = length × width; add waste; packs = area-with-waste ÷ pack coverage, rounded up.
Worked example
5 × 4 m room, 10% waste, 2.2 m²/pack. = 20 m² (22 m² with waste) → 11 packs.
