Estimate your general body type (somatotype) — ectomorph, mesomorph, or endomorph — based on your wrist circumference relative to your height.
This tool gives a rough estimate of your body frame type — ectomorph, mesomorph, or endomorph — based on the classic somatotype theory.
Body type is estimated using the ratio of height to wrist circumference, a simple proxy for skeletal frame size used in fitness assessments.
Enter your height and wrist circumference in centimeters, select your gender, then click Calculate.
Example: A higher height-to-wrist ratio generally suggests a leaner ectomorph frame, while a lower ratio suggests a broader endomorph frame.
Can I change my body type. Your basic frame is largely genetic, but training and nutrition can significantly change your muscle and fat composition regardless of frame.
Is this scientifically precise. It is a simplified estimate; true somatotyping involves more detailed anthropometric measurements.
