40 tiles
60 square feet of surface
A 60 square foot floor takes 40 tiles of 12 by 18 inches, because a 12 by 18 inch tile covers 1.5 square feet. Add your own waste allowance for the cuts at the walls.
A worked example
A 7 ft 6 in by 9 ft bathroom floor in 12 × 24 in tile, with a 10% waste allowance needs 38 tiles. 67.5 square feet at 2 square feet per tile is 33.75, and the 10% allowance takes it to 38.
What else it is called
Tile is sold as ceramic, porcelain and stone tile, and the long shapes as plank or wood-look tile. The count depends on the face size you select, not the material. Shops sell it by the box, so divide this count by the tiles per box printed on the label.

Where the numbers come from
- Tile coverage is the size you select, multiplied out: a 12 by 18 inch tile covers 1.5 square feet. You tell the page which tile you are buying, so no figure here is ours to source.
This counts the floor area you type in. It does not subtract a bath, a shower pan or cabinets, and it does not know your layout: a diagonal or herringbone pattern cuts more pieces than a straight grid, so raise the waste allowance for those.
