Floor Tile Thickness

Most floor tiles have a thickness of about 1/2 inch to 3/4 inch and are generally thicker than wall tiles. A tile's thickness usually depends on the material.

It's a natural material that develops when sediment is fused together from the heat of the earth's crust. It's a hard stone that is ideal for residential and commercial flooring. Variations in slate thickness depend on the size and type of the tile. Chinese and Indian slate 12-inch by 12-inch tiles can range in thickness from 3/8 and 7/16 inch. Chinese slate tiles of 16-inch by 16-inch can have a thickness of 1/2 to 9/16 inch, whereas Indian slate tiles of the same size can vary between 7/16 and 1/2 inch in thickness.
