Understanding your waist-to-hip ratio

Waist-to-hip ratio compares abdominal fat to hip fat, which relates to cardiovascular risk patterns. The World Health Organization uses different thresholds for men and women because fat distribution differs between sexes.

The formula

WHR = waist circumference ÷ hip circumference, using the same unit for both measurements.

WHO thresholds

Men: below 0.90 low, 0.90–0.99 moderate, 1.0+ high. Women: below 0.80 low, 0.80–0.85 moderate, 0.85+ high.

Measuring tips

Measure the waist at the narrowest point and hips at the widest point, keeping the tape level and snug but not tight.

How is waist-to-hip ratio calculated?

Waist-to-hip ratio (WHR) is your waist circumference divided by your hip circumference, measured in the same units.

What do the WHO risk categories mean?

The World Health Organization uses different WHR thresholds for men and women to flag low, moderate or high risk related to fat distribution around the waist.

Why does hip measurement matter?

Comparing waist to hip measurement reflects whether body fat is stored more around the abdomen or the hips, which relates to different health risk patterns.

Is waist-to-hip ratio a diagnosis?

No. It is a simple screening indicator used in cardiovascular risk assessment, not a medical diagnosis. Speak with a healthcare professional for personal advice.
