Determine your body type — ectomorph, mesomorph, or endomorph.
This calculator estimates your somatotype — ectomorph, mesomorph, or endomorph — using your body measurements including weight, height, waist, hip, and wrist circumference. Developed by psychologist William Sheldon in the 1940s, the three-type system remains a useful framework for tailoring training and nutrition to your natural build.
Three Somatotypes

Multi-Measurement
Uses BMI, waist-to-hip ratio, and wrist size (frame indicator) for a more reliable result.
Personalised Advice
Get training and nutrition recommendations specific to your body type.
Metric & Imperial
Works with kg/cm or lbs/in — all conversions handled automatically.
