Flooring Material Calculator
Quickly estimate the exact amount of flooring you need to purchase by factoring in room dimensions, waste margins, and box coverage specs.
Why do I need a waste factor?
A waste factor refers to the extra percentage of flooring you must order. You'll have offcuts, angled cuts around walls or cabinets, and occasionally a damaged plank.
- 5-10% Waste: Ideal for standard square or rectangular rooms.
- 15% Waste: Required for rooms with diagonal installations or multiple obstacles.
- 20%+ Waste: Best for very custom patterns (like herringbone) or many stairs.
Understanding Box Coverage
Hardwood, LVP, and laminate flooring is sold by the box/carton, not strictly by the square foot. Each manufacturer packs a specific square footage into a carton (usually between 18 and 30 sq ft). Our calculator divides your total needed square footage by box coverage and always rounds up so you don't run short.
