Quilting Calculator

Plan fabric before the first cut. Quilting Calculator works out purchase-ready yardage for backing, binding, batting, borders, blocks, sashing, and common piecing jobs.

START WITH THE QUILT
Enter the quilt size and fabric width, compare possible orientations, and review both the calculated requirement and the rounded purchase amount. Switch between imperial and metric units and save the fabric widths you use most often.

CALCULATE COMMON PIECES
- Backing, binding, batting, borders, blocks, and sashing
- Half-square triangles and flying geese
- Piece counts and standard quilt sizes
- Waste allowances and purchase rounding

KEEP PROJECTS ORGANIZED
Save projects, revisit calculation history, compare options, reuse templates, and export results for shopping or reference. Each calculator shows its assumptions and formula so you can check the result against a pattern.

Results are planning estimates. Always confirm fabric width, pattern instructions, seam allowances, and directional-print requirements before cutting.
