Doll Clothes Scaling Calculator
Calculate scale factor and pattern measurements for doll clothes.
Enter real-world garment dimensions and doll size to get scaled pattern dimensions automatically.
Making doll clothes from a real garment pattern requires proportional scaling. Get the scale factor wrong and the clothes will fit oddly even if the main doll measurement matches.
Scale factor:
scale = doll_measurement / real_measurement
Use the same body part for both; torso height works well. For a 30 cm doll vs. a 160 cm person: scale = 30/160 = 0.1875 (about 1:5.3).
Applying the scale:
doll_dimension = real_dimension x scale
A 60 cm skirt length becomes 60 x 0.1875 = 11.25 cm on the doll. A 35 cm chest circumference becomes 35 x 0.1875 = 6.56 cm.
Common scale references:
- Barbie-type dolls: 1:6 scale (scale factor ~0.167)
- American Girl / 18-inch dolls: 1:3 scale (scale factor ~0.333)
- Waldorf dolls (35-40 cm): 1:4 to 1:4.5
An important catch: Seam allowances do NOT scale. If you add 1 cm seam allowance on a real pattern, you still add 1 cm seam allowance on the doll pattern, not 0.1875 cm. Always add seam allowance after scaling.
Buttons, snaps, and closures don’t scale well either. Use the smallest available closure that works for the fabric weight. Doll clothes often use hook-and-bar or velcro because miniature buttonholes are difficult.
