Real-World Examples
Example 1
A room with dimensions 4m × 3m has an area of 12m².
Example 2
A room with dimensions 5m × 2.5m has an area of 12.5m².
Example 3
A room with dimensions 3.5m × 2m has an area of 7m².
Data & Statistics
| Tile Size (cm²) | Coverage (m² per box) |
|---|---|
| 30 × 30 | 0.9 |
| 45 × 45 | 1.35 |
| 60 × 60 | 1.8 |
| Room Dimensions (m) | Area (m²) | Wastage (10%) | Total Tiles Needed |
|---|---|---|---|
| 4 × 3 | 12 | 1.2 | 13.2 |
| 5 × 2.5 | 12.5 | 1.25 | 13.75 |
| 3.5 × 2 | 7 | 0.7 | 7.7 |
Expert Tips
- Always round up to the nearest whole number when calculating tiles needed to account for wastage.
- Consider the pattern of your tiles when calculating. Diagonal or herringbone patterns will use more tiles.
- Leave space for cuts and breakages. A common rule is to add 10% to your total tile needs.
