Tile Calculator

Work out exactly how much tile to buy for a floor or wall — tiles, boxes, thinset, and grout — for any tile size and layout. Includes a layout/waste comparison and a downloadable PDF material list.

Thinset and grout coverage vary with trowel size, joint width, and technique. Always buy a little extra and keep a spare box for future repairs. For planning purposes only.
