A yard of fabric is a unit of measurement that refers to the length of fabric equal to 36 inches or 3 feet. It is always measured along the selvage of the fabric using a measure like a yardstick. The width of the fabric can vary from 36 inches (0.90m) to 60 inches (1.5m) . However, the yard is not affected by the width of the fabric because the widths of fabric (WOF) can be different. A yard of fabric is always 36 inches, while a fabric width can be between 36 to 60 inches. When you buy fabric for your sewing projects, its usually sold by the linear yard. One linear yard is 36 inches long, and the width varies based on the roll of fabric.
