One rectangular room and one product with uniform effective pack coverage. Alcoves, thresholds, stairs, borders, pattern repeats, board-width layout, damaged pieces, batch variation and substrate preparation require separate checks.

FROM ESTIMATE TO ACTION

Use the result, not just the number.

Verify the inputs

Measure or document each input. If a value is only an estimate, record its source and test a conservative alternative.

Keep the calculation traceable

Save the input link or copied result together with the date, units and assumptions. A number without its inputs cannot be checked later.

Confirm the decision

Compare the estimate with the related guide, current product data and requirements that apply at your location before buying or building.

Inputs to verify

Room length (m): Measure the finished floor boundary.
Room width (m): Split irregular rooms into rectangles and total them.
Excluded floor area (m²): Subtract only areas that will definitely receive no flooring.
Layout and cutting allowance (%): Choose from room shape, board direction, pattern and supplier guidance.
Effective coverage per pack (m²/pack): Use the declared installed coverage for one complete pack.
