Material calculator
Flooring box calculator — LVP, laminate & hardwood
Estimate flooring boxes from room area, the square feet per box printed on your product label, and a layout waste allowance.
You'll need
17 boxes
Flooring boxes
- Area with waste
- 321 sq ft
What this assumes
- 300 ft² × (1 + 7%) ÷ 20 ft² per box.
- Box coverage is user-entered because the exact value is printed on the flooring label.
Coverage rates & sources
Every number this calculator uses is a published engineering constant — not an estimate we made up. Here is exactly what it assumes and where each value comes from.
- Typical laminate box coverage: ~20 ft²/boxSource: Common retail box size (Lowe's/Home Depot laminate ~20 ft²/box) — user-editable
- Typical LVP box coverage: ~20–30 ft²/boxSource: Vinyl-plank boxes commonly 20–24 ft² (some 30–40) — user-editable
- Straight-lay flooring waste: 5–10% (default 7%)Source: Standard floating-floor waste for cuts (Lowe's/flooring-industry guidance)
- Diagonal flooring waste: 15%Source: Standard for diagonal layouts
Before you buy
- Box coverage varies by product; enter the exact ft² per box printed on the label.
- Flooring cannot be bought by the partial box, so round up and keep a spare box for future repairs because dye lots change.
- Diagonal and herringbone layouts waste much more than straight runs.
This is a planning estimate, not a substitute for a pro's on-site measurement. For load-bearing, structural, or code-regulated work, confirm quantities with a licensed contractor.
