How this calculator works
Tiles per square foot = 144 ÷ (tile width × tile length in inches). A 3x6 subway tile is 144 ÷ 18 = 8 tiles per square foot. A 24x24 tile is 144 ÷ 576 = 0.25, or one tile per 4 square feet.
Boxes are what you actually buy. Tile is sold by the box and the box lists square feet of coverage, not tile count. Divide your total square footage — waste included — by the coverage printed on the box and round up. Never round down: mixing dye lots halfway across a floor is visible forever.
One caution on nominal sizes: a "12 inch" tile usually measures 11 7/8" and relies on the grout joint to make up the difference. For counting purposes the nominal size is close enough, but for a layout plan measure a real tile.
Use it with the square footage calculator, the waste factor guide and the tile box converter.
Frequently asked questions
How many 12x12 tiles per square foot?
Exactly one. A 12x12 tile covers one square foot before grout joints are considered.
How many tiles are in a box?
It depends on size: 12x12 usually 15–17, 12x24 typically 6–8, 24x24 3–4, and 3x6 subway 80–90. Boxes are sized to weigh roughly 40–60 lbs.
How do I convert square feet to boxes of tile?
Add your waste factor to the room square footage, divide by the square feet of coverage printed on the box, and round up to the next whole box.
How many 12x24 tiles in 100 square feet?
50 tiles, since each covers 2 square feet. Add 10–12% waste and buy 56 tiles, or 7 boxes of 8.
Does grout joint width change how many tiles I need?
Barely. A 1/8 inch joint on 12x12 tile changes coverage by about 2%, which the waste factor already absorbs.
