The number of 13 inch tiles needed will depend on the actual dimensions of the floor rather than the square footage. If the room is square, 169 tiles, with 1/16 inch or larger grouted seams, will completely cover it. If the floor is rectangular, additional tiles will be needed, the exact number depending on how many tiles must be cut. As a general rule, approximately 10 percent extra is usually sufficient to cover waste from cutting and accidental breakage.
