Body Type Calculator

Discover your somatotype (body type) based on a series of questions about your body's natural tendencies.

How to Use This Tool

Select your gender and answer the five questions about your body's natural tendencies. Each question has three options; choose the one that best describes you. Click 'Calculate' to see your somatotype and total score. Use the 'Reset' button to start over.

Formula and Logic

This calculator uses a simplified somatotype assessment based on five questions. Each answer is scored from 0 to 2, with lower scores indicating ectomorphic traits and higher scores indicating endomorphic traits. The total score (0-10) determines your body type: 0-3 (Ectomorph), 4-6 (Mesomorph), 7-10 (Endomorph).

Practical Notes

Remember that body type is just one aspect of your physical health. Most people are a combination of two somatotypes. Your results can guide your training and nutrition: ectomorphs may focus on strength training and calorie surplus, mesomorphs on balanced training, and endomorphs on cardio and calorie deficit. However, individual variation is huge—consult a fitness professional or dietitian for personalized advice. Also, body type can change with consistent training and diet over time.

Why This Tool Is Useful

Understanding your body type can help you tailor your fitness and nutrition plans to your natural tendencies. It provides a starting point for setting realistic goals and choosing the right training methods. While not a medical diagnosis, it offers insights into how your body may respond to different diets and exercises.

Frequently Asked Questions

Can my body type change over time?

Yes, with consistent training and dietary adjustments, you can shift your body composition. However, your inherent skeletal structure and natural tendencies will still influence your baseline.

Is the somatotype classification scientifically valid?

The somatotype theory was developed by William Sheldon in the 1940s and has been both used and criticized. While it provides a general framework, modern fitness professionals often use it as a rough guide rather than a strict classification.

Should I base my entire fitness plan on my body type?

No, body type is just one factor. Consider your goals, lifestyle, health status, and personal preferences. It's best to use this tool as a general guide and adjust based on your individual response to training and diet.

Additional Guidance

For accurate assessment, answer the questions honestly based on your natural state, not how you wish to be. If you're between two options, choose the one that resonates more. Remember that this tool is for educational purposes and not a substitute for professional medical or fitness advice.
