When using our 12×12 inch garage floor tiles, you can simply multiply the length by the width (in feet) of the garage to calculate the number of tiles you need to cover the floor area. For example, if you have a room that is 20 feet by 20 feet, you would need 400 tiles. You should round up if the length or width of the room is not a whole number. If the length of the room is 19 feet 4 inches, then use 20 feet in the calculation of the floor area. We recommend that you leave at least ½-inch of space between the tiles and walls or permanent structures because the tiles expand and contract with temperature fluctuations.
If you will need to cut the flooring to install it around any permanent structures such as columns, stairways, or walls, you will need to add about 6% to the square footage for the total number of tiles needed. In general, when the project requires cutting, you can expect between 4% to 7% additional tiles to account for waste.
ModuTile Flexible PVC garage floor tiles measuring 18 x 18 inches and cover 2.25 square feet each. If you have a garage that is 20 feet by 20 feet, then you divide 400 square feet by 2.25 to determine the number of tiles needed. When reviewing the Flexible PVC tile product page, you can enter the square footage of your project area and see the quantity of tiles needed for coverage automatically populate.
