The Three Somatotypes
Ectomorph: Thin, long limbs, fast metabolism — benefit from higher calories and strength training. Mesomorph: Athletic build, responds well to training — balanced macros work well. Endomorph: Wider frame, slower metabolism — benefit from lower carbs and more cardio. Most people are a blend of two types.
What is the Body Type Calculator?
The Body Type (Somatotype) Calculator analyzes your physical measurements to determine your primary physiological build: Ectomorph (lean and long), Mesomorph (muscular and athletic), or Endomorph (broad and high body fat). Knowing your body type helps you tailor your diet and training regimen for maximum results.
How It Works (Formula)
Your somatotype is determined by the ratio of your bone structure, muscle mass, and fat distribution. The calculator uses a geometric comparison of your shoulder, waist, and hip circumferences to classify your dominant physical traits.
$$ \text{Body Type} \propto \frac{\text{Shoulder Circumference}}{\text{Waist Circumference}} $$
A simplified representation of the structural ratio used to determine somatotypes.
How to Use It
Use a tape measure to find the circumference of your shoulders, chest, waist, and hips. Enter these values into the calculator, and it will instantly identify your dominant body type and provide specific dietary recommendations.
