How Many Tiles Do I Need?

Tile count starts with room area (length × width) divided by the area of a single tile — a standard 12"×12" tile covers exactly 1 sq ft, so a 100 sq ft room needs 100 tiles before waste.

Waste allowance matters more for tile than most materials: 10% is standard for a straight layout, but diagonal or herringbone patterns can push waste to 15% or more because of the extra cuts at every edge.

The Tile Calculator converts your room and tile dimensions into a tile count and, if you know your box coverage, a box count too.

Buy all the tile for one room from the same dye lot in a single order — color and shade can vary noticeably between production runs, even under the same product name, and a mismatched reorder months later is a common and hard-to-fix mistake.
