Body Type Calculator
Discover your unique body shape based on your bust, waist, and hip proportions.
Body Type Calculator
Your body type — or somatotype — influences how easily you build muscle, store fat, and respond to different diets. Knowing yours helps you tailor your training and nutrition for better results.
How to Use This Calculator
- Enter your height, weight, wrist circumference, and ankle circumference.
- Answer questions about your natural build, fat storage tendencies, and muscle gain speed.
- Click Calculate to see your primary somatotype and personalized recommendations.
The Three Body Types
Ectomorph:
- Naturally slim, small bone structure, fast metabolism
- Struggles to gain weight or muscle
- Recommendations: Higher calorie intake, higher carbs, heavy compound lifting, less cardio
Mesomorph:
- Athletic build, naturally muscular, moderate metabolism
- Gains muscle easily, moderate fat storage
- Recommendations: Balanced macros, varied training (strength + conditioning), moderate cardio
Endomorph:
- Larger frame, higher body fat, slower metabolism
- Gains muscle but also fat relatively easily
- Recommendations: Lower-carb approach, caloric deficit for fat loss, more cardio, high-intensity training
Important Caveat
Most people are a blend of two somatotypes, not purely one. Somatotypes describe tendencies, not destiny. Training, diet, and consistency override genetics far more than many people believe.
Common Mistakes to Avoid
- Using somatotype as an excuse — "I'm an endomorph, so I can't get lean" is not accurate. Somatotypes describe tendencies; they don't determine outcomes. Adherence to diet and training matters far more.
- Applying a rigid, somatotype-specific diet — Individual response to macros varies enormously. Use your somatotype as a starting point, then experiment and track results.
- Ignoring hybrid types — Most people have characteristics of two somatotypes. Recognizing this allows more nuanced training and nutrition programming.
Frequently Asked Questions
Can I change my body type?
Your bone structure is fixed, but body composition (fat vs. muscle ratio) can change dramatically. An endomorph can become very lean with proper diet and training; an ectomorph can build significant muscle over time.
Is somatotype scientifically valid?
Somatotypes are a descriptive tool developed in the 1940s by William Sheldon. Modern research supports the existence of individual variation in metabolism and muscle fiber composition, though the strict three-type classification is considered oversimplified by most exercise scientists.
What is the most common body type?
Most people are mesomorph-endomorph or mesomorph-ectomorph blends. Pure ectomorphs and endomorphs are less common. The average person carries more endomorphic tendencies in modern sedentary lifestyles than their underlying genetics might suggest.
Conclusion
Your body type is a useful starting framework for training and nutrition decisions — but don't let it limit your ambitions. The best diet and exercise program is one you can consistently follow. Use this calculator as a guide, not a destiny.

Measurement Tip
For the most accurate identification, measure your "High Hip" — the upper swell of the hip over the pelvic region, usually about 7 inches below your natural waist.
