What is the Tile Calculator?
The Tile Calculator helps you determine exactly how many tiles you need for a project, how much area a batch of tiles will cover, and the total cost including tiles, grout, and labor. It accounts for waste from cuts and breakage so you buy the right amount the first time.
3 Calculation Modes
Tiles Needed
Area ÷ Tile Area + waste. Includes grout estimate.
Coverage
Tiles × Tile Area → ft²/m²/yd².
Cost Estimate
Tile + Grout + Labor = Total.
