Natural Stone Thicknesses

The thicknesses change depending on the size of the stone.

  • Standard thickness for 12×12 tiles is 3/8″, 1″ for 18×18 and 3″ for 24×24 tiles.
  • The reason why the stone gets thicker as it gets larger is because the natural stones are brittle and the only way to ensure undamaged transportation & installation of larger stones is to supply thicker stones that can withstand the unpredictable conditions along the way.
  • Standard thickness for 16″-24″ square tiles varies from 0.5″ – 0.75″

Example: The thickness of a kitchen countertop is generally either 0.75″ or 1.25″. In the eastern U.S. the thicker is preferred, while western consumers prefer the thinner.

Natural stone vs Man-made tiles (made of Ceramic/Porcelain)

Both materials are of excellent quality and durability.

  • Ceramic/porcelain tile is a man-made product and natural stone is extracted from the earth.
  • Natural stone differs in color and no two pieces ever look the same. They are unique.
  • Many ceramic/porcelain tiles are made to imitate some type of stone. They are more controlled in range and deviation, however many people have trouble distinguishing between natural stone and ceramic/porcelain tile due to the improved technology used in modern day.
  • Natural stone requires long-term maintenance vs. ceramic/porcelain, which requires no extended upkeep and is virtually maintenance-free.
