Step 1
Measurements
Enter sleeve measurements
Choose a sleeve type, fill in arm measurements, and adjust sleeve settings.
Important fit note
This sleeve block is a drafting guide based on your measurements and selected settings.
We strongly recommend making a test version and checking sleeve fit and armhole compatibility before cutting final fabric.
Sleeve measurement guide
Before generating
How these inputs affect this pattern
Use the notes below to understand which measurements shape the draft, which options change construction, and what should be measured again when values conflict. Presets are starting points; the submitted values drive the result.
Arm length, bicep, wrist, elbow and cap height
Arm length and wrist set the lower sleeve; bicep plus ease controls upper-arm room. Elbow length positions the guide, while cap height controls the height and curvature of the sleeve head.
Long, relaxed, short or cap sleeve
Presets provide practical starting values for length, ease, and cap shape. Each measurement remains editable, so the sleeve is recalculated instead of scaled from a fixed-size pattern.
