Calculate total flooring needed including a waste allowance for cuts and damaged pieces, plus how many boxes to buy based on the coverage per box.
How it works
- Enter the room's length and width in feet.
- Adjust the waste allowance percentage (10% is standard).
- Provide the square footage per box to see the total number of boxes required.
Frequently asked questions
Why do I need a waste allowance?
Edge cuts, doorways, and corners all create offcuts. Diagonal patterns waste more because cuts are longer.
Should I buy extra for repairs?
Yes — buy 1-2 extra boxes. Dye lots change between production runs, making an exact match difficult later.
What flooring needs the most waste?
Diagonal or herringbone patterns need 15%+. Straight plank is 7-10%. Large format tiles are 10-15%.
