Waste is not optional on a real job. Cuts at the edges, diagonals, and any mistakes all consume tiles, and 10% is the usual minimum for a straight lay. Buying whole boxes means you can end up with more than the calculation shows, which is worth checking against the shop's returns policy.

What Is Tile Calculator?

The Tile Calculator works out how many tiles and boxes you need to cover a floor, including a waste allowance. It handles imperial and metric sizes, shows grout bag counts, and gives the cost per square foot.
