Overview

Analyze your body type (frame size) using wrist circumference, height, and weight measurements. This calculator uses the wrist-based frame size assessment and Sheldon somatotype classification.

Formula

Frame Size Index = Height (cm) ÷ Wrist Circumference (cm)

Male Standards:
• Small Frame: > 10.4
• Medium Frame: 9.6–10.4
• Large Frame: < 9.6

Female Standards:
• Small Frame: > 11.0
• Medium Frame: 10.1–11.0
• Large Frame: < 10.1

Somatotypes (Sheldon):
• Ectomorph: Lean build, difficulty gaining muscle
• Mesomorph: Muscular build, responds well to training
• Endomorph: Wider hips, tendency to store fat

How to Use

  1. 1Enter your height in cm.
  2. 2Measure and enter your wrist circumference in cm (measure just above the wrist bone with a tape measure).
  3. 3Select your gender.
  4. 4Your frame size and estimated body type are analyzed automatically.

Tips

  • Wrist circumference has minimal body fat, making it a reliable indicator of bone structure.
  • Most people exhibit a blend of two or more somatotype characteristics.
  • Frame type is genetic, but body composition can be significantly changed through training and diet.
  • Ectomorphs benefit from higher calorie intake; endomorphs benefit from more cardio.
  • Body type analysis is a reference tool — individual training responses vary widely.

FAQ

Q. Can my body type change?

Your skeletal structure (bone frame) does not change, but muscle mass and body fat percentage can be dramatically altered through exercise and diet. For instance, even an ectomorph can build significant muscle with proper resistance training and caloric surplus.

Q. How do I measure wrist circumference accurately?

Wrap a tape measure snugly around your wrist just above the wrist bone (styloid process). Avoid pulling too tight or leaving it loose. For greater accuracy, measure both wrists and average the values.

Q. Should my workout program differ based on body type?

Body type is a reference indicator; your personal goals and fitness level matter more. That said, ectomorphs tend to benefit from compound lifts and caloric surplus, endomorphs from added cardio and dietary management, and mesomorphs generally respond well to a variety of training approaches.
