Nominal vs Actual Tile Size

Did you realize that the 24”x 48” porcelain tile you’re eyeing may not precisely measure 24×48 inches? Understanding industry size terminology is crucial when selecting flooring or wall tiles. It’s important to clarify the significance of “nominal” and “actual” dimensions in porcelain tiles. Although tile is sold by square footage, knowing these terms aids in design layouts and pairings with different tiles.

Porcelain and ceramic tiles are often identified by nominal sizes, following international standards. Tiles from Italy, Spain, the US, etc., adhere to the Metric System, labeled in both cm and inches for customer convenience. A 24” x 48” tile roughly corresponds to the actual 60cm x 120cm, with an ‘actual’ size of 23 5/8 x 47 1/4. So, if your tile measures slightly less than the advertised 48”, it’s normal.
