Mesomorph
Naturally athletic with an efficient metabolism. Mesomorphs gain and lose weight easily and respond well to both strength and cardio training. They benefit from balanced training and nutrition.
Endomorph
Naturally larger frame with a slower metabolism. Endomorphs gain weight easily and excel at strength activities. They benefit from cardio-focused training and mindful nutrition.

The Science Behind Body Types
Understanding somatotype theory and its practical applications
What is Somatotype Theory?
Somatotype theory, developed by psychologist William Sheldon in the 1940s, categorizes human body types into three main classifications: Ectomorph, Mesomorph, and Endomorph. While modern science recognizes that most people are a combination of these types, understanding your dominant somatotype can provide valuable insights into your fitness and nutrition needs.
Our calculator uses a combination of physical measurements and metabolic characteristics to determine your body type classification, providing you with personalized recommendations based on established scientific principles.
Frequently Asked Questions
Everything you need to know about our body type calculator
Can I be a combination of body types?
Yes! Most people are a combination of body types, with one being dominant. Our calculator identifies your primary body type while recognizing that you may have characteristics from other types as well.
Can my body type change over time?
Your fundamental body type is largely determined by genetics and remains relatively stable. However, your body composition, fitness level, and metabolism can change significantly with proper training and nutrition, which may affect how your body type characteristics manifest.
Which method is more accurate: quiz or measurements?
Both methods are designed to be accurate. The measurements method provides objective data based on physical dimensions, while the quiz method considers metabolic and behavioral characteristics. For the most comprehensive assessment, you can try both methods and compare results.
Is this calculator suitable for all ages?
Our calculator is designed for adults (18+). Body type characteristics are most stable in adulthood. For teenagers and children, body types are still developing, and results may be less accurate.
How should I use these results?
Use your body type results as a starting point for understanding your body's natural tendencies. Combine this knowledge with your personal goals, preferences, and any guidance from healthcare professionals to create a personalized fitness and nutrition plan.
