Are ectomorph, mesomorph, and endomorph scientific diagnoses?

No. They are historical and fitness-language labels. This calculator uses them only as rough body-build shorthand.

Can my body type change?

Your adult bone frame changes little, but your appearance can change with muscle, fat, posture, age, training, nutrition, and health status.

Should I train or eat based only on body type?

No. Use actual goals, weight trend, performance, medical context, and sustainable habits. The body-type estimate is only background context.

Body Type Calculator

Estimate a current ectomorph, mesomorph, or endomorph body-type tendency from wrist circumference, with optional BMI context and cautious limitations.

Heuristic body-type estimate only. Ectomorph, mesomorph, and endomorph labels are fitness shorthand, not medical diagnoses or fixed identities.

Sex

Wrist circumference (cm)

Height (cm, optional)

Weight (kg, optional)

What This Body Type Calculator Does

This page estimates a current body-type tendency using wrist circumference and optional BMI context. It follows English search intent around ectomorph, mesomorph, and endomorph labels while keeping the result framed as a heuristic.

BMI = \frac{weight _{k g}}{height _{m}^{2}}

Optional BMI context when height and weight are provided.

Not a fixed identity

Somatotype labels are descriptive shorthand. They do not diagnose health, metabolism, personality, or training potential.

How To Measure

Measure the narrowest part of the wrist with a flexible tape.
Keep the hand relaxed and do not compress the skin.
Repeat the measurement and use a typical value, especially near a category boundary.
Use height and weight only as optional BMI context, not as a full body-composition assessment.
