Estimate your general body type (somatotype) — ectomorph, mesomorph, or endomorph — based on your wrist circumference relative to your height.
This tool estimates your general body type or somatotype — commonly categorized as ectomorph, mesomorph, or endomorph — based on measurements like wrist circumference, height, and build. Body type classification is often used informally in fitness planning to guide training and nutrition approaches.
The three somatotype categories describe general tendencies: ectomorphs tend to be naturally lean with a fast metabolism, mesomorphs tend to build muscle relatively easily with an athletic frame, and endomorphs tend to have a higher natural body fat percentage and gain weight more easily. Most people are a blend of these categories rather than a pure type.
Enter your measurements (typically wrist circumference and height, sometimes frame size indicators), and the calculator suggests your likely dominant body type tendency.
Example: A person with a small wrist circumference relative to height is often categorized as leaning ectomorph, while a larger wrist-to-height ratio may suggest a mesomorph or endomorph tendency.
Is body typing scientifically precise? Somatotype theory is a useful general framework, but modern exercise science recognizes that body composition is influenced by many overlapping factors, and most people don't fit neatly into just one category.
Can my body type change over time? While genetic tendencies remain fairly constant, training, nutrition, and lifestyle changes can significantly shift muscle mass and body fat percentage regardless of your general somatotype.
Should I choose a workout plan based only on body type? Body type can offer general guidance, but individual goals, current fitness level, and how your body actually responds to training are typically more important factors for designing an effective program.
What's the difference between mesomorph and endomorph? Mesomorphs typically build muscle easily with a naturally athletic build, while endomorphs tend to carry more body fat and may need to focus more on nutrition and cardio for fat loss goals.
Is this calculator a substitute for a body composition scan? No, this provides a general estimate based on simple measurements; methods like DEXA scans or skinfold calipers give a much more precise picture of actual body composition.
