What is this calculator?
Heuristic frame classification from wrist and height measurements. The formula, a worked example, and a reference table are below. Results are for education only, not medical advice.
How it works
Heuristic: height (cm) ÷ wrist circumference (cm); thresholds near ~9.6–10.4 suggest small/medium/large frame labels (educational).
Example
Height 170 cm, wrist 17 cm → ratio ≈ 10.0 → “medium” heuristic band.
Reference Table
| Value | Meaning |
|---|---|
| Wrist | Bony prominence, same tape tension |
| Frame label | Not diagnostic |
| Ideal weight | Cross-check other tools |
FAQ
Scientific validity?
Frame heuristics are weak predictors of health outcomes.
Bone density?
Osteoporosis care needs imaging, not wrist ratios.
Why include it?
Users search it; we explain limits transparently.
Better metrics?
Waist, strength, VO2, and lab markers where appropriate.
