How to Figure Out Sq Ft for Tile



If you’re new to tile, the industry standard is that you need about 122-144 square feet to lay one tile, which is about 3 inches by 3 inches. But Ted, who is knowledgable, could only calculate to about 100, whereas Missy calculated to a staggering 700 square feet. What the heck is going on?


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.

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:


- Measuring a Shower – Showers can be divided into rectangular sections (which is the easy part), but if you have a niche or a bench, that’s a few extra measurements to keep track of. Separate each section by the tiles you plan to use, grouping by material to calculate the square footage needed for all surfaces. Don’t forget to include the depth of the sides of niches and windows too! If you plan to have border tiles, calculate them the same way you measured for trim above, by measuring the perimeter of the shower area and dividing the number by 12 to determine the total linear feet of border tiles needed for your design!

- Measuring a Bathroom Floor – Measuring a bathroom floor is definitely easier than measuring a shower, but there are additional factors to keep in mind. Drains, vanities, toilets or any other items that take space on the floor must be considered in your measurements when tiling bathroom floors. We always recommend tiling underneath those items for future updates to the bathroom! (Source: www.tileclub.com)
