Calculate how many tiles you will need based on the size of the tile and the square footage of the area you are tiling. This number is the exact amount you will need, but it is recommended that you add an additional 10% because some tiles will need to be cut. Enter the size of the tile (the size of one side of the tile in inches) and the total square footage of the area to be tiled below then press “Calculate.”
