Body Frame Size Calculator
Estimate body frame size from height and wrist circumference. Informational only, not medical advice.
This tool uses a common height-to-wrist ratio method to label frame size as small, medium, or large.

How it works
A simple frame-size estimate compares height to wrist circumference. Smaller wrists relative to height usually map to a smaller frame label, while larger wrists relative to height usually map to a larger frame label.
Examples
- 170 cm height and 16 cm wrist → height-to-wrist ratio ≈ 10.63
- 5 ft 7 in height and 6.3 in wrist → imperial values are converted internally
- Useful as a broad reference alongside other body measurements
FAQ
- What does this calculator estimate?
It estimates body frame size from height and wrist circumference using a simple height-to-wrist ratio.
- What is body frame size?
Body frame size is a broad reference label such as small, medium, or large, often estimated from skeletal proportions.
- Is this a medical assessment?
No. It is a general reference estimate only, not a medical diagnosis or full body composition assessment.
- Can I use imperial measurements?
Yes. This calculator supports both metric and imperial inputs and converts them internally.
- Are my measurements stored?
No. All calculations run locally in your browser.
