Calculated Frame Size

Based on your wrist-to-height ratio.

Estimated Primary Body Type

This determines metabolic rate and muscle growth potential.

What is the Body Type (Somatotype) Calculator?

The Body Type (Somatotype) Calculator uses basic anthropometric measurements—height and wrist circumference—to classify your foundational body structure. Understanding your primary Somatotype (Ectomorph, Mesomorph, or Endomorph) is exceptionally useful for tailoring diet and exercise routines for maximum effectiveness. This classification helps explain why some individuals naturally find it easier to gain muscle mass, while others struggle with body fat storage.

In-Depth Look at the Three Body Types

While few people fall strictly into one category, identifying your predominant type using the Body Type Calculator allows for better goal setting. Knowing your genetic blueprint helps you work *with* your body, not against it. [Image of Ectomorph, Mesomorph, and Endomorph Somatotypes]

  • Ectomorph (Linear Frame): Ectomorphs have a naturally thin, linear build with a high metabolism. They often struggle to gain either weight or muscle mass due to their fast energy burn.

    Training Focus: Prioritize heavy strength training, minimize steady-state cardio, and maintain a high calorie/carb intake.

  • Mesomorph (Athletic Frame): Mesomorphs possess an athletic, medium bone structure and an efficient metabolism. They typically gain muscle and strength easily and maintain a lower body fat percentage without extreme effort.

    Training Focus: Maintain a balanced regimen of resistance training and moderate cardio, consuming moderate and balanced macronutrients.

  • Endomorph (Rounder Frame): Endomorphs have a larger bone structure and a slower metabolism, making them prone to storing body fat. However, they are often naturally strong and powerful.

    Training Focus: Focus on high-intensity interval training (HIIT) and consistent cardio, coupled with moderate weight training and careful control of carb and fat intake.

Calculation Method for Your Body Type

This Body Type (Somatotype) Calculator utilizes the height-to-wrist ratio to determine your Frame Size, which correlates strongly with the physical characteristics of the three somatotypes. The ratio is calculated as:

Ratio = Height (in) ÷ Wrist Circumference (in)
            
GenderFrame SizeWrist Ratio Thresholds (Height / Wrist)
MaleLarge Frame (Endomorph)Ratio < 9.6
MaleSmall Frame (Ectomorph)Ratio > 10.4
FemaleLarge Frame (Endomorph)Ratio < 10.1
FemaleSmall Frame (Ectomorph)Ratio > 11.0
Ratios between these ranges suggest a Medium Frame (Mesomorph).

Historical Context

The concept of somatotypes was originally developed by psychologist William Sheldon in the 1940s. While modern fitness science recognizes that physique is highly influenced by diet and training, somatotyping remains a foundational tool for determining an individual’s structural predisposition. For further reading on the historical origins of this classification system, you can explore academic references related to William Sheldon’s initial work on somatotyping.
