Body Shape Calculator

Enter your shoulders, bust/chest, waist and hips to estimate your body shape based on proportions.

What you will need
  • A flexible measuring tape (cm or inches).
  • Pen/paper or your phone to record each of the 4 readings.

Measure on bare skin where possible. The tape should be snug but not digging in or compressing tissue.

How this calculator works

This tool estimates your body shape using simple proportions between your shoulders, bust/chest, waist, and hips. It’s not about “good” or “bad” shapes — it’s a quick way to understand how your measurements distribute.

What “body shape” means here

“Body shape” refers to your measurement pattern (where you carry width), not your fitness level, health status, or worth. Two people can share the same shape and look completely different.

What we compare

  • Shoulders vs hips (top-heavy vs bottom-heavy balance)
  • Waist relative to shoulders/hips (how defined the midsection is)
  • Bust/chest for extra context (especially for male/female patterns)

Getting accurate measurements

  • Measure on bare skin if possible, with the tape level.
  • Keep it snug, not compressing tissue.
  • Stand relaxed, normal breath — don’t suck in your waist.
  • Take 2–3 readings and use the most consistent number.

How to use the result

  • Clothing: helps guide cuts that balance shoulders/hips.
  • Training: can help you focus on symmetry (e.g., upper vs lower emphasis).
  • Progress tracking: you can re-check after a phase of training/fat loss.

Your shape can shift over time — especially with muscle gain, fat loss, and posture changes.

Common reasons results feel “off”

  • Tape isn’t level (tilted tape inflates numbers).
  • Measurements taken over thick clothing.
  • Waist is measured too high/low (not the narrowest point).
  • Shoulders measured too far forward/back.

Limitations (important)

  • This is an estimate based on a few circumference points.
  • Different methods define shapes slightly differently.
  • “Shape” doesn’t diagnose health or replace medical advice.

Borderline outcomes are normal — small measurement differences can switch categories.

Mini FAQ

Is body shape the same as body type (ecto/meso/endo)?

No. Body shape is about proportions (shoulders/waist/hips). Body type (frame) is more about bone-structure tendency (wrist/ankle/knee/elbow). They answer different questions.

Can my body shape change?

Yes. Muscle gain, fat loss, and posture changes can shift your proportions over time. The categories are not permanent.

What if I’m between two shapes?

That’s common. If your numbers are close, treat the result as a spectrum. Re-measure calmly and use the same method each time.

Should I measure shoulders “around” or “across”?

For this calculator, measure around the widest part of your shoulders/delts, keeping the tape level. (That matches how bust/waist/hips are taken.)

How often should I re-test?

Only if you’re tracking changes — for example every 4–8 weeks during a training or cut phase. Otherwise, once is enough.
