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.

Usually tile is sold in square meters. If you would like to order floor tile, all you need to know is the footage of the room: for instance if the area of your kitchen is 10 sq. meters, you will be ordering 10 m of tile + some extra for the borders and trim (usually around 10 percent).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.
