How much flooring should I order?
Calculate the room area, add waste, then divide by the coverage printed on each carton. Ten percent waste is common for straight layouts; diagonal patterns, irregular rooms, and products with more color variation may need more.
Multiple rooms
Calculate each room separately and add their areas before applying waste. Measure closets and alcoves, and subtract only permanent areas that will not receive flooring.

Frequently asked questions
Should I add extra material?
Yes. Most projects need an allowance for cuts, breakage, uneven surfaces, overlap, or measurement error. The appropriate percentage depends on the material and layout.
Can I use this estimate to place an order?
Use it to plan and compare costs, then verify package coverage and project requirements with the manufacturer, supplier, or qualified contractor before a large purchase.
