How to Measure Accurately
Measurement Tips:
- •Stand straight with arms at sides
- •Keep tape snug but not tight
- •Measure over bare skin or fitted clothing
- •Take measurements at the same time of day
- •Breathe normally, don't hold breath

Body type (or somatotype) describes your natural body shape based on bone structure and how your body distributes weight. The three main classifications are ectomorph (naturally lean), mesomorph (naturally athletic), and endomorph (naturally broader). Understanding your body type can help tailor fitness and nutrition approaches.
The Three Somatotypes
| Type | Characteristics | Tendency |
|---|---|---|
| Ectomorph | Narrow shoulders and hips, lean, long limbs | Struggles to gain weight or muscle |
| Mesomorph | Athletic build, medium frame, gains muscle easily | Responds well to both exercise types |
| Endomorph | Wider hips, rounder build, higher body fat tendency | Gains weight easily, loses it slowly |
Body Shape Classifications for Women
Women's body shapes are often described by waist-to-hip and shoulder-to-hip ratios: Hourglass (similar bust and hips, defined waist), Pear/Triangle (hips wider than bust), Apple/Inverted Triangle (bust/shoulders wider than hips), Rectangle (similar measurements throughout).
Waist-to-Hip Ratio = Waist / Hips Healthy range: Women < 0.85, Men < 0.90 Waist-to-Height Ratio = Waist / Height Healthy: < 0.5 for most adults
Frequently Asked Questions
Is somatotype scientifically validated?⌄
The original somatotype system developed by William Sheldon in the 1940s has been largely rejected as pseudoscience in its original form (he linked body types to personality traits). However, the descriptive framework for body composition tendencies remains useful as a practical shorthand. Modern understanding recognizes that body composition is a spectrum influenced by genetics, diet, and training, not a fixed category.
Can you change your body type?⌄
You cannot change your fundamental skeletal structure (bone width, height). However, training and nutrition can significantly change your body composition. An endomorph can achieve a lean physique with appropriate training and diet. An ectomorph can build substantial muscle. The body type concept is most useful for setting realistic expectations and informing training approaches.
What is the healthiest body type?⌄
No somatotype is inherently healthier. Health is determined by body composition (fat vs muscle), metabolic markers, fitness level, and lifestyle, not by your natural frame type. Endomorphs may need to be more intentional about diet and exercise, while ectomorphs need to ensure adequate protein and caloric intake. All body types can achieve excellent health.
How do I determine my body shape?⌄
Measure your bust/shoulders, waist, and hips at their widest points using a soft measuring tape. Compare the three measurements: If bust ≈ hips and waist is significantly smaller: hourglass. If hips > bust: pear. If shoulders/bust > hips: inverted triangle or apple. If all three are within a few inches: rectangle. These are guidelines, not strict classifications.
