How it works
The formula behind this calculator.
tiles = area / (tileLength × tileWidth); +10% for waste
- area
- Total area to cover
- tileSize
- Length and width of one tile
Smaller tiles mean more grout lines and more labor. Order extra for cuts and breakage, more for diagonal patterns.
Example: 10 m² with 30×30 cm tiles → 10 / 0.09 = 111 tiles; +10% = 122
Ref: Tile Council of North America guidelines
Tips
- 💡 Tile quantity = area + 10% waste. For diagonal patterns, 15%.
- 💡 Smaller tiles mean more grout lines and more work but allow for more complex shapes.
