About This Calculator
About the Fabric Yardage Calculator
Our Fabric Yardage Calculator helps sewers, quilters, and upholsterers determine the exact amount of fabric needed for any project. Whether you are making patchwork quilts, curtains, clothing, or home decor items, this calculator minimizes waste and ensures you buy just enough fabric without costly shortages.
The calculator uses a simple layout optimization algorithm. It first determines how many pieces fit across your fabric width by dividing the fabric width by each piece width and rounding down. Next, it calculates how many rows of fabric you need by dividing the total pieces required by the pieces-per-row and rounding up. Finally, it multiplies the number of rows by the piece length to give the total yardage in inches and yards, along with the estimated waste.
Regional Notes
India: Fabric is commonly sold in meters. Use 1 yard = 0.9144 m to convert. Standard fabric widths in India for cotton are typically 44 in (112 cm). The calculator uses inches and yards as standard sewing measurements.
United States: Fabric is sold by the yard. Common widths include 44/45 in for quilting cotton, 60 in for apparel and broadcloth, and 108 in for quilt backing. Most US sewing patterns specify yardage in 44-45 in or 60 in widths.
United Kingdom: Fabric is sold in meters in most shops, though some specialty stores sell by the yard. Standard widths are 45 in (115 cm), 60 in (150 cm), and 140 cm (55 in). Remember 1 meter = 1.094 yards when converting from our calculator results.
How to Use
Select your fabric width from the dropdown, then enter the width and length of each piece you want to cut (in inches). Enter the total number of identical pieces you need. Click "Calculate Yardage" to see the minimum fabric required and a complete cutting layout breakdown.
Frequently Asked Questions
How does the Fabric Yardage Calculator work?
The fabric yardage calculator divides your fabric width by the width of each piece to determine how many pieces fit across. It then divides the total pieces needed by that number to calculate rows, rounding up to ensure you have enough fabric. Finally, it multiplies the rows by the piece length to give you the total inches and yards of fabric required.
How many yards are in a bolt of fabric?
A bolt of fabric typically contains 30 to 100 yards depending on the material thickness. Lightweight fabrics like cotton may have 50 to 100 yards per bolt, while heavier upholstery fabrics average 30 to 60 yards per bolt. Always check the bolt label at your fabric store for exact yardage.
How big is a yard of fabric?
A yard of fabric is 36 inches or 3 feet in length. A yard of 60-inch-wide fabric covers 15 square feet, while a yard of 44-inch-wide fabric covers 11 square feet. Fabric is sold by the linear yard, so the width is fixed per roll and you buy the length you need.
What if my piece width is wider than the fabric width?
If your piece width exceeds the fabric width, the calculator will not produce a result. You need to choose a wider fabric or reduce your piece width. Always check that your piece width is smaller than the fabric width so at least one piece fits across.
Should I add extra fabric for seam allowance?
Yes, for most sewing projects we recommend adding 0.5 to 1 inch per side for seam allowance to your piece width and length before entering them into the calculator. For example, if your finished piece is 11 in by 11 in, enter 12 in by 12 in to account for 0.5 in seam allowances on each side.
What fabric widths are commonly available?
Common fabric widths vary by type. Quilting cotton is typically 44 to 45 in wide. Home decor and upholstery fabrics come in 54 in widths. Broadcloth and apparel fabrics are often 60 in. Bedding fabrics and wide backings are available in 108 to 120 in widths. The calculator supports all standard sizes from 44 to 120 in.
How much fabric do I need for a quilt?
For a standard twin quilt (60 in x 80 in) using 44-inch-wide fabric, you typically need 5 to 6 yards. A queen quilt (84 in x 92 in) requires 8 to 9 yards. Use the fabric yardage calculator by entering your piece size (e.g., 12 in squares) and the number of squares needed to get the exact yardage.
How do I calculate fabric for multiple pieces of different sizes?
Calculate fabric for each unique piece size separately, then add the yardage together. Enter the largest pieces first since they determine how many rows you need. For complex projects with many different sizes, consider laying out your pattern pieces on a cutting diagram to optimize fabric usage and minimize waste.
