Body type distribution

The chart visualizes the likelihood for each somatotype based on your inputs.

What is a body type (somatotype)?

Somatotype is a practical way to describe your natural build and how your body tends to store muscle and fat. The classic three types are ectomorph (leaner frame), mesomorph (naturally more muscular), and endomorph (softer, rounder tendency). While most people are a blend, knowing your dominant tendency helps tailor training and nutrition with more confidence.

Body type is not destiny. It’s just a starting point to make smarter choices about your routine.

How this calculator estimates your body type

This tool blends common indicators—Body Mass Index (BMI) and Waist-to-Hip Ratio (WHR)—to infer a likely somatotype. BMI approximates body mass relative to height, while WHR offers a glimpse into fat distribution. Combined, they offer a simple, globally accessible way to estimate your tendency without specialized equipment.

Quick guide: training and nutrition by body type

  • Ectomorph focus: Prioritize compound lifts, slightly higher calories, and adequate protein. Keep cardio modest to support mass gains.
  • Mesomorph focus: Balanced strength and conditioning with steady protein. Periodize training to avoid plateaus.
  • Endomorph focus: Emphasize progressive resistance, daily activity, and nutrient-dense meals. Manage calories and include higher-protein options.

For students and professionals

Students can use this as an entry point to concepts like energy balance, body composition, and anthropometrics. Health and fitness professionals can use it for quick client education, pairing results with individual assessments and goals.

Frequently asked questions

HOW TO use the Body Type Calculator?

Choose your unit system, enter height, weight, waist, and hip measurements, select sex (optional for WHR thresholds), then click Calculate. You’ll see BMI, WHR, and an estimated body type with a 3D chart.

HOW TO measure waist and hips correctly?

Measure waist at the narrowest point above the navel without compressing the tape. Measure hips at the widest point around the buttocks, keeping the tape level and snug but not tight.

HOW TO improve my results over time?

Train consistently 2–4 times per week, prioritize protein, sleep 7–9 hours, and adjust calories to match your goals. Retest measurements every 4–6 weeks to track changes.

HOW TO interpret BMI and WHR together?

BMI estimates mass relative to height; WHR hints at fat distribution. Together they provide context for your somatotype tendency but should be considered alongside training history, diet, and health markers.

HOW TO use this calculator worldwide?

Switch between metric and imperial units. All calculations convert internally, so results are consistent across countries and regions.
