Enter measurements below. Results update as you type, and optional prices can be added before sharing the estimate.
Measured area
Room length × room width.
Purchase area
144 sq ft plus 10% waste = 158.4 sq ft.
Box count
Purchase area divided by product-label box coverage, rounded up to whole boxes.
Cost
Optional box or area price plus optional whole underlayment rolls.
The calculation
Measured area × (1 + waste) ÷ product box coverage, rounded up
Quick examples

Common questions
Measure each room or section, add the areas, apply a waste allowance for layout and cuts, divide by the product coverage per box, and round up to whole boxes.
Enter the exact square-foot or square-metre coverage printed on the carton. The calculator divides the waste-adjusted area by that coverage and rounds up to a whole box.
The appropriate allowance depends on room shape, installation direction, plank pattern, closets, transitions, damaged pieces, and future repairs. Use the product or installer recommendation rather than relying on one fixed percentage.
Yes. Select laminate, enter room area, waste, coverage per box, and an optional price. The same workflow also supports LVP and engineered or solid hardwood cartons.
Yes. Use the exact carton coverage for the hardwood product. Random-length boards, grading, installation method, and lot availability may justify a different waste allowance.
It can. Enable separate underlayment, enter the coverage per roll and optional price, and the result rounds the required roll quantity upward.
Yes. Choose price per square foot or square metre, or price per box. Area-based cost uses the actual coverage purchased after whole-box rounding.
Yes. Copy estimate link stores the room, material, pattern, waste, box coverage, underlayment, and price inputs in a reusable URL.
