Online Parametric Pattern Drafting
BJD Hanfu Jiaao Pattern Generator
Use doll bust, garment length and total sleeve length to create a custom Ming-style jiaao pattern.
Measure scale, bust, garment length and sleeve span
This tool uses scale ratio, doll bust, garment length and total sleeve length. Total sleeve length is the full distance from one cuff across the arms and shoulders to the other. Measure the specific doll rather than relying on its nominal scale label alone.
Check sleeve span and miniature body proportions
In the preview, focus on body length, the horizontal sleeve span and the front overlap. Entering a one-sleeve measurement as total sleeve length will shorten the draft substantially; after changing scale, also review the visual proportion between cuffs and body.
Test fabric thickness and dressing access
The overlap, lining and cuffs of a miniature jiaao can accumulate bulk quickly. Verify the printed scale and test in material close to the final thickness, checking closure placement, dressing access and arm movement before deciding how to handle seam allowances.
