Flooring for an 8×10 room by waste allowance
| Waste | Sq ft to buy | Boxes (20 sq ft) | Boxes (24 sq ft) |
|---|---|---|---|
| 5% | 84 sq ft | 5 | 4 |

An 80 sq ft room is typical of a bedroom, office or kitchen. Box sizes vary a lot between products (roughly 15–30 sq ft), so enter your exact box coverage in the calculator above.
The math
8 ft × 10 ft = 80 sq ft
× 1.10 waste = 88 sq ft
÷ 20 sq ft/box = 5 boxes (rounded up)
Also plan 80 sq ft of underlayment if your planks don't have it attached, and about 36 linear feet of baseboard or quarter-round for the perimeter (less door openings).
