Calculate Your Flying Geese

Uses the standard 2:1 Flying Geese proportion and one trim-friendly four-at-a-time method.

The finished width is always twice the height. Enter 2" to make a 2" × 4" finished unit.

Flying Geese can face different directions, so this count does not define a quilt-top size.

Make Four at a Time

Use one large Goose square and four small Sky squares for each batch. The pieces are intentionally a little larger, so you can trim the finished units accurately.

How This Plan Works

This calculator uses one method: oversized Flying Geese made four at a time. Cut one Goose-fabric square and four Sky-fabric squares for each batch, then trim for accuracy.

View assumptions
  • The unit is the standard 2:1 proportion: width is twice the finished height.
  • Cutting sizes use the locked oversized formula: finished width + 1 1/2 in for the Goose square and finished height + 1 1/8 in for each Sky square.
  • Trim each unit to the listed unfinished size before piecing it into your quilt.
  • Yardage uses the usable WOF you enter, then rounds buying amounts up to the next quarter yard.

FAQ

Each oversized four-at-a-time batch makes four matching Flying Geese units.

Finished size is the size visible after the unit is sewn into a quilt. The unfinished size is 1/2 inch larger in both directions for seam allowance.

This method makes four units at a time, so a requested quantity that is not divisible by four is rounded up to complete batches.
