Tile Count and Grout Volume
Tile count with waste and grout cubic-inch estimate.
Example
You enter
- Area (ft²) 100
- Tile width (in) 12
- Tile height (in) 12
You get
- Base count 100
- Tile count (with 10% waste) 110
- Tile face (in²) 144
- Grout volume 75 in^3
Details, formula, and sources
Tile count = floor area / tile_area + per-edge cut allowance. Grout volume = joint_area × depth × waste factor.
