What is this tool?
Flooring is usually sold by the box with a stated coverage in square feet. Divide your room area (plus a waste allowance for cuts and mistakes) by coverage per box, then round up. Patterns, diagonals, and irregular rooms often need more waste.
How to use it
- Enter room dimensions or total area.
- Set box coverage and waste percentage.
- Order the ceiling number of boxes and keep a spare if matching lots matters.
