Flooring Needed
Flooring Area is calculated by multiplying the room length by width, then adding a waste percentage.
Area = Length × Width
Total with Waste = Area × (1 + Waste%)
Recommended waste percentages:
- Simple rectangular room: 5–7%
- Diagonal or herringbone pattern: 10–15%
- Complex room shapes / many cuts: 15–20%
Common flooring box sizes (imperial):
- Laminate/engineered: ~20 sq ft per box
- Hardwood planks: ~18–22 sq ft per box
- Tile (12×12): ~10 sq ft per box
Common flooring box sizes (metric):
- Laminate/engineered: ~1.8–2.0 m² per box
- Hardwood planks: ~1.7–2.0 m² per box
- Tile (30×30 cm): ~1.0 m² per box
Tips:
- Always round up to the nearest full box
- Buy extra from the same batch to ensure color consistency
- Keep leftover material for future repairs
