Body Type Calculator
Answer a few measurements - bust/chest, waist, hips and wrist - to get an estimated somatotype with training and nutrition tips suited to it.
Waist-to-hip ratio
0.86
Frame size
Medium
Waist-to-height ratio
0.47 (healthy)
Somatotype tendency
Balanced mesomorph-leaning - athletic proportions
Classic somatotypes are a rough guide, not destiny - resistance training and nutrition can substantially change body composition within your frame.
How to Use the Body Type Calculator
- Measure chest/bust, waist, hips and wrist circumference.
- Enter sex, height and the measurements above.
- View your estimated body type plus its training and diet tendencies.
Formulas Used
Waist-to-hip ratio = waist / hips (apple vs pear distribution)
Waist-to-height ratio = waist / height (>0.5 suggests central adiposity)
Frame index = height(cm) / wrist circumference(cm) determines frame size
Frequently Asked Questions
Are somatotypes scientifically valid?
The original 1940s somatotype theory is outdated as a strict classification, but the measurement ratios used here (WHR, WHtR, frame size) are still useful health indicators.
What does my waist-to-height ratio mean?
A ratio under 0.5 is generally considered healthy. Above that suggests increased cardiometabolic risk regardless of overall BMI category.
Can I change my body type?
You cannot change bone structure or where fat preferentially stores, but resistance training and nutrition can substantially change muscle mass and composition within your frame.
