Formula
- Total area = sum of each room length x width.
- Waste area = total area x waste percent / 100.
- Area to buy = total area + waste area.
- Boxes needed = area to buy / coverage per box, rounded up.
Example
For 500 sq ft with 10% waste and boxes covering 23.5 sq ft, purchase 550 sq ft and buy 24 boxes.

How much flooring waste should I use?
Ten percent is a common starting point for simple layouts, but angled rooms or pattern matching may need more.

Yes for basic area and box estimates, provided you enter the correct box coverage.
