Body Type Calculator
Get an indicative somatotype tendency — ectomorph (lean, straight frame), mesomorph (athletic V-shape), or endomorph (rounder midsection) — from simple shoulder, waist, and hip ratios. Most people are a blend; treat the result as a rough guide, not a diagnosis.
Inputs explained
- Shoulder circumference — Around the widest point of your shoulders, in centimetres.
- Waist circumference — Around your natural waist, in centimetres.
- Hip circumference — Around the widest point of your hips, in centimetres.

Understanding the result
Example: Shoulders 110 cm, waist 75 cm, hips 95 cm gives a shoulder-to-waist ratio of 1.47 and waist-to-hip ratio of 0.79 — a mesomorph tendency.
Frequently asked questions
Is this the same as an official somatotype classification? No, true somatotyping (the Heath-Carter method) uses skinfold thickness, bone breadth, and limb measurements; this calculator only uses shoulder, waist, and hip circumference ratios as a simplified, indicative approximation.
Can someone's body type change, or is it fixed from birth? The shoulder-to-waist and waist-to-hip ratios this calculator measures can shift with changes in muscle mass, body fat, and training, so the result reflects your current build rather than a permanent, unchangeable category.
