If you think you are done after selecting tile materials, sizes, and patterns, you’re mistaken. The most important detail is selecting a grout joint width, which is the spacing or gap between each tile in the assembly. Why is grout joint width so important? First and foremost, it will prevent tripping and breaking the edge of the tile. By increasing the spacing between the tiles, it reduces the slope of the transition from one tile to the next tile. Shoes are less likely to catch on a tile edge and wheels of carts roll freely over the tile surface.
Plus, grout joint width can make or break a professional looking tile job. When installing wall and floor tiles, installers place plastic spacers between each one to ensure the lines remain uniform. Tile spacers range in size from 1/16 ” to 1/2 ” but finished grout joint widths will vary from 1/16″ to 3/16″. Using the smallest grout possible will increase installation time. Once the tile mortar sets, the installer can remove the spacers but the spacing cannot be changed. Before installing any tile, it’s important to choose the grout width size you want and stick with it! There is really no standard sizing guidelines for grout lines, according to the Tile Council of North America. However, a 1/8″ grout line size is what most interior designers and tile installers prefer since it tends to give a more luxurious look when finished. There are several factors you should consider when selecting a grout width size such as the tile’s size, whether the tile edges are irregular or straight, whether the surface is level, where in the home you’re installing the tile, how much the tiles vary in size, and the aesthetic or look you want to achieve. So, how do you determine what grout joint width you should use for your tile project? Below are some common grout joint sizes to help you select what would work best for you.
