Step-by-step
- Coverage needed = 200 × 1.1 = 220 ft².
- Boxes = ⌈220 / 22⌉ = 11.
How to use this calculator
- Enter room area.
- Enter box coverage (from manufacturer spec).
- Pick type for waste-factor guidance.
About this calculator
Flooring is sold by the box (or by sq yd for carpet). Coverage per box varies by manufacturer and type. Standard waste: 10% for clean rectangles; 15-20% for diagonal patterns or complex layouts. Always order extra — manufacturer dye lots vary, so post-install matching is hard.
Frequently asked
Cuts at room edges, mistakes, replacement panels. Diagonal patterns: 15-20%. Pattern-matched: even more.
