How much 12x12 ceramic tiles come to a box?

The sq ft per box as well as the # of tiles per box vary based on the manufacturer and the sub brand. But, generally, they tend to range from 10 to 20 per box for 12 x 12 tile. (the boxes are too heavy if there are more).

Often, for 12 x 12 tile, I see 11 and 15, but it will vary based on the item you select.
