Info

What is Waist-to-Hip Ratio (WHR)?

Waist-to-Hip Ratio (WHR) compares the size of your waist to your hips to give a quick indication of body fat distribution. A higher WHR can be linked to greater cardiometabolic risk. WHR is a screening indicator and not a diagnosis.

Use WHR together with other measures (e.g., BMI, waist circumference, lifestyle factors).

How to measure correctly

  • Waist: Measure at the narrowest point between ribs and hips (or just above the navel) after a normal exhale.
  • Hips: Measure at the widest part of the buttocks/hips.
  • Keep the tape level and snug but not compressing the skin. Measure on bare skin for accuracy.
  • Take 2–3 readings and use the average.

Tip: Measure at the same time of day to stay consistent.

Formula

Units & formula

Formula

WHR = Waist ÷ Hip

Example: 80 cm ÷ 95 cm = 0.84

Units

Use either cm ÷ cm or in ÷ in

WHR is unitless — just be consistent.

Helpful tips

  • Use a flexible tape measure and stand naturally (don’t suck in).
  • Measure over bare skin for accuracy.
  • Record to one decimal place (e.g., 82.5 cm).
Warning

Common mistakes

  • Mixing inches with centimeters.
  • Measuring hips too high (not at the widest part).
  • Holding your breath or tightening the tape.

Frequently asked questions

How is WHR different from BMI?

BMI reflects weight relative to height; WHR reflects fat distribution. Both are estimates and should be considered together.

Is a lower WHR always better?

Extremes aren’t ideal. Aim for a healthy range; consult with a professional for personalized targets.

Can I improve my WHR?

Balanced nutrition, regular activity, sleep, and stress management may help change fat distribution over time.

Important note

WHR is a general health indicator and does not diagnose conditions. Work with a healthcare professional for assessment and planning.
