There are some basic rules of thumb in calculating the correct amount of flooring to order. First calculate the square footage. To do that, measure the length and width of the room, round them up to the closest foot and then multiply them together. If you are going to be placing the tiles so they are parallel with a wall, then you should add 7 -10% extra square footage to your order. If you are going to place your tiles on a diagonal to the walls, then you should add 15-20% extra square footage. This extra is your allowance for cuts you’ll need to make, errors and plus a few extras for possible future replacements. Please remember that our custom manufacturing process is a batch process and an exact color match request to your existing cork flooring is difficult. Additionally, you’ll have to wait for another production cycle to get the extra tiles. It is much safer to order enough flooring the first time.
