📏 Body Frame Size Calculator
🔍 What is Body Frame Size? It classifies skeletal structure (small, medium, large) based on height vs. wrist circumference.
Used worldwide by health professionals to adjust ideal weight ranges and assess body composition. This advanced tool uses the height-to-wrist ratio method (frame index = height (cm) / wrist (cm)), with gender-specific cutoffs validated across multiple ethnicities (USA, Europe, Asia, etc.). Determines if you have a delicate, average, or robust frame.

⚥ Gender
Male & female thresholds differ: men have slightly larger bone density, therefore cutoffs are sex‑specific: Male (small >10.4, medium 9.6–10.4, large <9.6). Female (small >11.0, medium 10.1–11.0, large <10.1).

📏 Height (cm/in)
Taller individuals generally have higher frame index if wrist is proportionally smaller. Index = height / wrist. Height measured without shoes.

✋ Wrist circumference
Key bone marker. Smaller wrist relative to height → small frame; larger wrist → larger bone structure. Measured at narrowest point below styloid.
