Flooring Calculator
Estimate how much flooring material you need, including a waste factor for cuts, and how many boxes to buy based on the coverage printed on the box.
- Room area
- 120 sq ft
- Material needed (with waste)
- 132.0 sq ft
- Boxes to buy
- 7 boxes
How this is calculated
Room area = length × width. Material needed = room area × (1 + waste factor). Boxes = material needed ÷ coverage per box, rounded up.
Assumptions
- Waste factor defaults to 10% to cover cuts and mistakes; adjust for diagonal layouts or irregular rooms.
- Boxes are rounded up to whole boxes.
