How do I convert the number of quilt pieces to yardage?

Enter your piece size and count above. The calculator tiles pieces across your usable WOF, figures out how many cutting rows you need, and converts to yardage. Make sure you're entering cut size (with seam allowances), not finished size.

Should I add extra yardage for cutting waste?

Always. Round up to the next quarter yard at minimum, or add 10-15% for a fabric you can't easily replace. It's cheaper to have leftovers for your stash than to drive back hoping the same dye lot is still on the shelf.

Does piece shape affect the yardage calculation?

The calculator uses the bounding rectangle. For squares and rectangles, that's the piece itself. For HSTs, it's the parent square you cut diagonally. If your pattern gives finished sizes, add seam allowances before entering dimensions.

Buy yardage, not guesswork

Always buy extra. Fabric isn't always on-grain, you lose a bit squaring up edges, and one cutting mistake shouldn't tank your project. Round up to the next quarter yard, or add 10-15% for a fabric that's hard to replace. Leftover fabric just goes in the stash.

Directional prints need more yardage because you can't rotate pieces freely — you're locked into one orientation, which means more waste per row. Fat quarters give a different yield than yardage for the same total area because of the shape — wider but shorter. If your pattern gives FQ-friendly cutting layouts, follow those instead of converting to yardage blindly.

Enter cut sizes, not finished sizes. A 3" finished square is 3.5" cut. If you're resizing a pattern or designing your own quilt and don't have a yardage chart, this calculator does the conversion the shop needs — a yardage number instead of a piece count.
