Estimated result
Enter measurements and select Calculate.
Tile quantity method
Surface area is divided by one tile’s area, then multiplied by 1 + the entered allowance and rounded up to whole tiles. Boxes are rounded up from the entered tiles-per-box value.
Installation boundaries
This estimate does not optimize layout, patterns, grout joints, edge cuts, breakage, box dye lots, substrate, or installation requirements. Verify actual tile and box coverage.
Worked example
A 12 ft by 10 ft surface using 12-inch square tiles requires 120 tiles before allowance and whole-box rounding.
Estimate boundaries
