Flying Geese Calculator

Flying geese are a classic quilt block. This calculator estimates the cut sizes for sky squares and geese rectangles, plus the fabric yardage needed.

Calculate your project

Formula

Sky square cut size = finished height + 0.5 inches. Geese rectangle = (finished width + 0.5) × (finished height + 0.5) inches.

Example calculation

For a 4 inch x 2 inch finished geese unit, cut sky squares at 2.5 inches and geese rectangles at 4.5 x 2.5 inches.

Results are planning estimates. Always round up when buying fabric, especially for directional prints, shrinkage, fussy cutting, or cutting mistakes.

Frequently asked questions

Does this work for the no-waste flying geese method?

This uses individual sky squares and geese rectangles. The no-waste method (four geese at once) uses different measurements.

How many sky squares per geese unit?

Two sky squares are needed for each finished flying geese unit.

What seam allowance is used?

A standard 1/4 inch seam allowance is included in the cut size formulas.

Can I make oversized geese for trimming?

Yes. Some quilters cut slightly larger and trim for accuracy. Adjust the finished size accordingly.
