How to Calculate Tiles Needed
Calculating the number of tiles for your project involves measuring your space, determining tile coverage, and adding extra for waste and cuts.
Step-by-Step Calculation
- Measure the length and width of your area
- Calculate total square footage (length x width)
- Determine tile coverage per tile (tile length x tile width)
- Divide area by tile coverage
- Add 10-15% for waste and cuts
Common Tile Sizes
| Size (inches) | Coverage per Tile | Common Use |
|---|---|---|
| 4" x 4" | 0.11 sq ft | Accent tiles, backsplash |
| 6" x 6" | 0.25 sq ft | Backsplash, small areas |
| 12" x 12" | 1 sq ft | Floors, walls |
| 12" x 24" | 2 sq ft | Modern floors |
| 18" x 18" | 2.25 sq ft | Large floors |
| 24" x 24" | 4 sq ft | Large open spaces |
Why Add Extra for Waste?
- Cuts and breakage: Tiles at edges need cutting, some may break
- Pattern matching: Diagonal or complex patterns need more tiles
- Future repairs: Keep extra tiles for replacing damaged ones
- Color variations: Tiles from different batches may vary slightly
Recommended Waste Percentages
- Straight lay: 10% extra
- Diagonal lay: 15% extra
- Complex patterns: 15-20% extra
- Large tiles in small rooms: 15% extra
Tips for Tiling Projects
- Always buy all tiles at once from the same lot/batch
- Dry-lay tiles before installing to check pattern
- Start from center of room for balanced cuts at edges
- Use appropriate grout width for tile size
- Store extra tiles flat in a dry place for future repairs
