Tile Calculator

Calculate floor or wall tile quantity from project dimensions, subtract openings where needed, add a visible waste allowance and convert the result into whole boxes.

Tiles to purchase

Tile quantity formula

Tile area = tile length × tile width
Purchase tiles = ceiling(net surface area ÷ tile area × (1 + waste rate))

Wall mode subtracts the door and window areas you enter before calculating tiles. Whole tiles and whole boxes are always rounded up.
