Flooring Calculator

Estimate floor area and add a configurable waste allowance.

Enter one rectangular section at a time, or enter the combined net area from your own room sketch. Adding carton coverage lets the calculator round up to a purchasable quantity.

Formula

Purchase area = length × width × (1 + waste ÷ 100). If carton coverage is entered, cartons = purchase area ÷ carton coverage, rounded up.

For L-shaped rooms, calculate rectangles separately and add them before waste. Patterned layouts may need a larger allowance.
