Hexagons are popular for English paper piecing and modern quilt designs. This calculator helps you plan hexagon projects.

Calculate your project

Formula

Hexagon width = side length × 2. Cutting template size = finished size + seam allowance. Yardage is estimated from template rows.

Example calculation

A hexagon with 1" sides has a width of 2" across the flat sides and needs about 1.25" template for ¼" seam allowance.

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