Selecting the pattern for the installation of your new tiles has never been easier. With this floor pattern tool, you can select whether the project will use one size of tile, two different sizes of tiles, or multiple tile sizes. Then, you will select the pattern desired. The most popular tile sizes for the pattern selected appear, and after that quick selection, you only need to input the dimensions of the room. The floor pattern tool figures the number of tiles needed based on the square footage and desired waste.
