Finding Yardage Needs by Fabric Width
To determine your yardage needs for a window treatment or slipcover, measure your furniture or window first. Use this table to easily convert your yardage needs from one width to another. Most decorator fabrics are 60 inches wide, which is why that column is shaded in the table below, so start your calculations based on 60-inch wide fabric. If you need 2 yards of 60-inch fabric but the fabric you love is 45 inches wide, just slide your finger from the 60-inch column to the 45-inch column; you need 2-3/4 yards for the same coverage.
