Figuring Out Square Feet for Tile


Though your designer may give you the specs, you want the square footage for tiles if you want to calculate what your quality would be. What is the square footage of a tile? Plotting out the square footage is simple, make a grid and divide the plot in half. Start with one or two of the left-hand side and then plot out the other half with the right-hand side. Then, use a distance between the grids and multiply them to get your answer.


To allow for waste, you must consider the installation. For most standard installations, 10% extra for waste is sufficient. Percentage of waste for more elaborate patterns like running tile on a 45 degree angle, herringbone or cross hatch, consult with your installer. Add 15% for tile being installed in a room with lots of jogs and corners. These installations will require more cuts and thus more waste.

Floor or wall tiles are typically installed with gaps between the tiles because the average tile may look quite similar to the next tile, but they are often not uniform in shape and size, and would not fit properly if installed without any gaps. These gaps are most commonly filled with grout, and as such, are often referred to as grout size, or grout lines. Grout is a form of concrete, and the gap between tiles can range from anywhere between one-sixteenth of an inch to half an inch in size. Different sized tiles, materials, and design needs all affect the size of the gaps. Although it is typically more difficult to have small gaps between tiles due to lack of a uniform shape and size, the use of rectified tiles (tiles that undergo additional processing to ensure that they are uniform) can allow for smaller spacing, though at an additional cost. For more uniformly cut tiles such as granite, smaller grout spacing can result in less visibility of grout lines between each tile. (Source: www.calculator.net)
