Standard porcelain tile thickness ranges between 1/4- and 3/4-inch thick. In contrast, ceramic tiles range from 1/4- to 3/8-inch in standard thickness. According to the Utah State University Cooperative Extension, thicker tiles are less likely to break or crack than thinner tiles.

Counting the number of tiles. Now that you have the area of a single tile, all you need to do is divide one sq. meter by this area and you will get the number of tiles. So for the 20x20 cm tile the calculations are going to look like this: 1 sq. m / 0.04 sq. m = 25.herefore, the tile of 20x20 cm size has an area of 0.04 sq. m. If the tile size is 30 cm by 60 cm, the calculations indicate 0.3m x 0.6m=0.18 sq. m. For the tile that is 12,5cm x 120cm the area is going to be 0.125m x 1.2m=0.15sq.
