How Many Floor Tiles Do I Need?
Quick Answer
Approximately 37 tiles for a 12m² room
Based on: 12m² floor area, 600×600mm tiles, 10% wastage allowance
How We Calculated This
- Floor area: 12m²
- Tile size: 600 × 600mm = 0.36m² per tile
- Tiles needed: 12 ÷ 0.36 = 33.3 tiles
- Plus 10% wastage: 33.3 × 1.10 = ~37 tiles
Tiles Per m² by Common Sizes
- 300 × 300mm: ~11.1 tiles/m²
- 450 × 450mm: ~5.0 tiles/m²
- 600 × 600mm: ~2.8 tiles/m²
- 800 × 800mm: ~1.6 tiles/m²
- 600 × 300mm: ~5.6 tiles/m²
Wastage Allowances
Always order extra tiles to cover cuts, breakages, and future repairs:
- Straight lay: 10% extra
- Diagonal/diamond lay: 15% extra
- Complex patterns (herringbone): 15–20% extra
- Rooms with many alcoves or angles: 15% extra
Tips
Buy all tiles from the same batch to ensure colour consistency. Keep a few spares for future repairs — manufacturers regularly discontinue ranges.
