Metric Flooring Calculator

Estimate flooring from one or more labelled rectangular zones, selected waste, box coverage, and optional box price.

Zones

Split L-shaped or connected spaces into rectangles, then add each rectangle below.

Waste percent (%)Commonly used for cuts, joins, and matching planks.Box coverage (m2)Use the m2 coverage printed on one unopened box.Price per box (optional)Used only to multiply whole boxes by your entered price.

Estimate

Enter measurements and calculate to see the flooring estimate.

Formulas and assumptions

Each zone area = length x width.
Raw area = the sum of all rectangular zone areas.
Waste-adjusted area = raw area x (1 + waste percent / 100).
Boxes required = waste-adjusted area / box coverage, rounded up to a whole box.
Layout direction, board pattern, damaged pieces, stairs, thresholds, and supplier pack coverage can change actual flooring needed.

Planning estimate only. Not engineering, structural, legal, installation, or supplier advice. Check measurements, site conditions, and product labels before buying or building. This flooring estimate uses the zone measurements and box coverage entered on this page.
