There are typically between 30 and 100 yards of fabric in a bolt of fabric while the width of the fabric is often between 45 and 60 inches. When buying fabric in bulk, the bolt is usually the preferred amount to purchase.
When purchasing fabric at a fabric store, the clerk will get the bolt of fabric from the shelf and measure the material to the exact yardage desired by the customer. These bolts are usually not purchased by customers unless they need a significant amount of fabric and want to buy in bulk. Many different kinds of fabric are available in bolt form for those people who do want to buy in bulk, such as twill, tulle, cotton, canvas, muslin, burlap, and flannel. The bolt refers to the wooden or cardboard tube that the fabric is wrapped around and the fabric itself.
For those people who are interested in saving money, premeasured and precut pieces of fabric, known as remnants, are available in fabric stores at discounted prices. These remnants are sometimes available in bolts, although they are typically available in smaller amounts, and typically labeled with both the width of the fabric and the amount of yardage.
