Formula and Assumptions
Tile count = area / tile module area, adjusted for waste and rounded up.
Actual conditions, local rates, product labels, and contractor recommendations can change the final quantity or cost.
Example Calculation
An 80 sq ft area with 12 inch tile and 10% waste needs about 88 tiles.
Tips
- Buy all tile from the same lot.
- Use higher waste for diagonal patterns.
- Keep spare tiles for repairs.
