Frequently asked questions
How many rolls for a 4 × 3 m room?
With 2.5 m walls, a standard Euro roll and no pattern repeat about 8–9 rolls (14 m perimeter ÷ 0.53 m ≈ 27 strips, 3 strips per roll) – fewer if you deduct doors and windows.
Why count strips instead of m²?
Offcuts at the end of each roll can't always be used; counting whole strips per roll is more realistic.
