Fabric Yardage Calculator 🧵
Calculate fabric yardage needed to cut a specific number of quilt pieces. Enter piece size, quantity, and fabric WOF to get exact yardage requirements.
How to Use the Fabric Yardage Calculator
Enter the cut size (not finished size) of each piece, the number of pieces you need, and your fabric's width of fabric (WOF). The calculator determines how many pieces fit across one row and how many rows you need.
The yardage rounds up to the nearest 1/8 yard for practical cutting. Always add a small buffer (5-10%) for fabric defects, directional prints, and cutting mistakes.
For directional prints or plaids that require pattern matching, you may need to add extra yardage — typically 1 repeat length per yard of fabric. This calculator assumes non-directional fabric.
Frequently Asked Questions
How do I calculate fabric yardage for a quilt?
Determine the cut size of each piece (finished size + seam allowances), how many pieces you need, and your fabric width (WOF). Divide the WOF by the piece width to get pieces per row, then divide total pieces by pieces per row to get rows needed. Multiply rows by piece height to get total inches, then convert to yards.
Should I add extra fabric for mistakes?
Yes, always add a 10-15% buffer for cutting mistakes, fabric defects, and directional prints. For beginners, add 20-25% extra. It's much easier to have leftover fabric than to run short mid-project.
How does fabric width affect yardage calculations?
Wider fabric means more pieces per row, which means fewer rows and less total yardage needed. Always use the usable width (after removing selvages), not the full bolt width. Most quilting cotton has 40-42" usable width.
What about directional prints?
For directional prints (fabric with a clear up/down orientation), you may need to cut pieces in only one direction, which can significantly increase yardage requirements. Add extra yardage equal to one pattern repeat per yard of fabric.
