How to Use This Calculator
- Measure your room — Get the length and width with a tape measure. For L-shaped rooms, break them into rectangles and calculate each separately.
- Choose your laminate specs — Pick thickness (8mm is standard) and AC rating (AC3 for most homes). These affect durability and price.
- Select installation pattern — Standard is easiest with least waste. Diagonal looks great but needs 15% extra material.
- Enter box coverage — Check your flooring packaging. Most boxes cover 18-25 sq ft.
- Review results — See total square footage and boxes needed. Enable cost estimate to plan your budget.
How We Calculate
Boxes Needed = (Length × Width × (1 + Waste%)) ÷ Box Coverage
Example Calculation:
- • Room: 12 ft × 15 ft = 180 sq ft
- • Waste factor: 10% (standard installation)
- • With waste: 180 × 1.1 = 198 sq ft
- • Box coverage: 20 sq ft/box
- • Boxes needed: 198 ÷ 20 = 10 boxes
