How much fabric is required to upholster a wing back recliner?

My quasi-educated guess would be around 7 yards. Depending on the size and style of the chair, it could be as low as 6 yards or as high as 8 yards.

If the fabric has a repeating pattern or the chair has a skirt you may need as much as 11 yards. Take digital pictures of the chair from the front, back and side and measure it height, width and depth. Take the pictures with you when you are looking for upholstery fabric and ask for assistance with the yardage.
