Floor Tile Sizes (Standard Dimensions Guide)

This guide to floor tile sizes includes the standard dimensions for square & rectangular shapes, thickness, and different bathroom, living room & kitchen floor designs.

Different types of floor tiles

Flooring is one of the many ways a homeowner can elevate the total look of their home during construction or renovation. Many tiles are available with different designs and sizes for every room of a home, from the kitchen to the bathroom floor. 

Homeowners can achieve a traditional grid pattern with specific tiles, but they can also achieve an edgy diner-style checkerboard pattern with black and white colors. 

Aside from the floor, tiles are also very versatile in that they can be used for walls. Kitchens and bathrooms are usually where homeowners can select designs for tiles to be used on walls.

Standard Floor Tile Sizes

Different types of floor tiles are available in many colors, styles, shapes, and sizes for the homeowner to fully personalize their space and interior design. The size will also depend on what material they are made of and their specific and intended use. Through the years, the standard tile size has also increased with the need and trend of larger pattern floor designs. 

Standard tile sizes are available from the smaller .5 by .5 inches or 1.27 by 1.27-centimeter mosaic tiles to the larger 24 by 24 inches or 61 by 61 centimeters products found in most commercial spaces. 

The most popular standard floor tile sizes are 12 by 12 inches, 18 by 18 inches, and 12 by 24 inches in width. Do keep in mind that while an individual piece may be referred to as being 12 by 12 inches, the actual ‘true’ measurement is often 11-7/8 inches by 11-7/8 inches.

How Thick Are Flooring Tiles?

Other than the length and width of tiling, another dimension to consider is the floor tile’s thickness. There are ultra-slim tiles available at 6 millimeters or .24 inches and also standard ones at 10 millimeters or .39 inches, which are the most frequently used and versatile thickness. Tiles used for walls are usually in this or between these sizes

If a homeowner wants thicker tiles, the hefty 20-millimeter products are some of the toughest available for pavers. Thickness is critical because it will dictate how high the floor will end up after construction or renovation

Rectangular Tile Dimensions
