Body Shape Reference
A published classification method (FFIT) applied to your measurements — reference labels with the rules shown, not a judgement or a size promise.
Classification runs locally in your browser — measurements are never uploaded or logged.
Reference classification
Enter bust, waist and hips, then classify.
The method behind this
This tool applies the Female Figure Identification Technique (FFIT), published in the apparel research literature (K. Simmons, C. Istook & P. Devarajan; extended to plus sizes by S. Sokolowski & B. Bettencourt, 3DBody.Tech proceedings). The method compares bust, waist, hips and high-hip in inches and assigns one of nine figure classes, grouped into five families: hourglass, pear, inverted triangle, rectangle and apple.
High hips only matter for one decision: the same hip-forward silhouette splits into Bottom Hourglass (high hip ÷ waist < 1.193) or Spoon (≥ 1.193). Without that input the tool reports both as candidates.
The nine reference classes
Hourglass family: Hourglass · Bottom Hourglass · Top Hourglass — bust and hips roughly balanced with a clearly smaller waist.
Pear family: Spoon · Triangle — hips lead the bust.
Inverted triangle family: bust leads the hips.
Rectangle family: bust and hips similar, waist not much smaller.
Apple family: Oval · Diamond — waist equals or exceeds hips/bust.
Limits you should know
- FFIT was developed on female bodies; there is no equally published male method, so this tool does not offer one.
- A shape label is a styling reference, not a medical, health or attractiveness judgement — and it is not a clothing-size or fit guarantee.
- Boundary measurements can legitimately match more than one class; the tool lists them instead of pretending false precision.
Frequently Asked Questions
Is this a judgement of my body?
No. It is a geometric classification used in apparel research — a styling shorthand, nothing more. It says nothing about health, weight or appearance, and it is not a medical assessment.
Why does the result sometimes list two shapes?
Measurements on a boundary legitimately satisfy more than one rule. The tool lists both candidates rather than rounding you into a fake single answer.
Why no men's classification?
FFIT was built and validated on female body scans. No equivalently published male method exists, so we show none rather than inventing thresholds.
Will this tell me my clothing size?
No — shape and size are different questions. For sizes, use the brand clothing-size tool; this page is only about proportions.
Classification follows the published FFIT rule set (Simmons, Istook & Devarajan; Sokolowski & Bettencourt plus-size extension). Computed locally — your measurements never leave the browser.
