Approximately 13 yards of fabric are needed to cover an average size love seat, and the fabric should be at least 54 inches wide. If the fabric has large, repeating patterns, more fabric is necessary.
To figure an exact yardage, sketch each individual part of the love seat on a notepad. Measure the length, width and height of each part at its widest spot, and jot down on the sketch. Decide which pieces can lay beside one another on 54 inch wide fabric. Measure the length of each segment of pieces, and add the lengths together. Divide the total by 36 inches to convert inches to yards.
