Our TrueLock Rubber Flooring is perfect for home gym flooring and is the same material and grade widely used in commercial fitness centers. Each tile is 24 inches by 24 inches. We highly recommend ordering field tile and cutting off a small amount on the perimeter for a square look. For an easy DIY installation we offer corner pieces that have locks on two sides and are straight on two sides. We also offer edge pieces which are straight on one side. All tiles are sold 9 tiles to a pack. Corner tiles include 4 corners and 5 edge pieces. If you had an area that was 10 feet x 10 feet for example, you would need 4 corners, 12 edge pieces and 9 field tiles. Or, you could just order 3 boxes of the field tile and trim the edges off. Tiles can be easily trimmed with a utility knife and a straight edge.<
