Flooring Calculator

Estimate how many flooring pieces and optional boxes are needed with a waste allowance. Your data is processed in your browser.

How to use

  1. Enter room length and width in meters.
  2. Enter piece dimensions in centimeters and waste percentage.
  3. Optionally enter pieces per box, then calculate.

How it works

The room area receives the waste allowance and is divided by one piece's area. Counts are rounded up.

Notes and limitations

  • Cuts, layout, defects, and irregular shapes may require a different allowance.
  • Adhesive, grout, and baseboards are excluded.

Frequently asked questions

Why are counts rounded up?

Pieces cannot be purchased as fractions, so the estimate uses the next whole unit.
