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. You may want to choose thicker porcelain tiles for flooring, especially in high-traffic areas.
Therefore, in one square meter there will be exactly 25 tiles that are 20x20 cm in size. For the tile that is 30x60 cm the results are going to be the following: 1/0.18 = 5,555(5). So you will have about five and a half tiles.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.
