How Many Tiles Do I Need?

Tile quantity depends on the installation area, actual tile dimensions and allowance for cuts, breakage and layout. This chart includes 10% extra material.

Counts include 10% extra and assume nominal tile dimensions represent the coverage used for planning. Verify actual product dimensions, grout-joint layout and box coverage before purchase.

Tile quantity formula

Convert the tile dimensions to square feet, divide the installation area by the area of one tile, add the chosen extra-material allowance, then round up to a whole tile. When buying boxed tile, round up again to complete boxes based on the manufacturer’s coverage per box.

Example: 100 ft² with 12 × 24 tile

A 12 × 24 in tile covers about 2 ft². A 100 ft² area needs about 50 tiles before extra material. With 10% extra, plan for 56 tiles after rounding up.

Calculate tiles and boxes

Use exact project dimensions, tile size, waste allowance and box coverage.

Patterns can change waste

Diagonal, herringbone and other layouts can create more offcuts than a straightforward grid. Room shape, obstacles and tile dimensions also matter, so use the chart as a starting point rather than a substitute for the actual layout.
