Tile Calculator
Calculate floor area, tile count, waste allowance and estimated boxes for flooring or wall tile.
Use this tile calculator to estimate how many tiles you need for a rectangular room or wall. Enter the space dimensions, the tile size and a waste margin for cuts, breakage and a practical spare.
How the calculation works
The room area is length × width. Tile area converts centimeters to meters, then divides the total area by the area of one tile. The result is rounded up and the waste percentage adds a realistic buffer for installation.
If the project has niches, irregular corners or multiple areas, calculate each section separately and add the totals before you buy.
Use clear inputs to get a more useful result.
