How It Works
Calculating tile quantity requires knowing your room area and tile size. Always add a waste factor for cuts, breakage, and future repairs.
The Formula
Tiles = (Room Area / Tile Area) x (1 + Waste%)
Variables
- Room Area — Room length x width in square feet
- Tile Area — Single tile coverage in square feet
- Waste% — Extra percentage for cuts and breakage (typically 10-15%)
Example
A 12x10 room (120 sq ft) with 12"x12" tiles and 10% waste: 120 tiles + 12 waste = 132 tiles total.
Tips
- Always buy 10-15% extra tiles for cuts, breakage, and future repairs.
- Diagonal or herringbone patterns need 15% waste factor.
- Keep leftover tiles for future repairs — matching discontinued tiles is difficult.
- Larger tiles mean fewer grout lines but more waste from cuts.
