What waist-to-hip ratio shows
Waist-to-hip ratio (WHR) divides your waist circumference by your hip circumference. It captures how fat is distributed rather than how much you carry overall. A higher ratio means more weight around the abdomen relative to the hips, a pattern linked to greater cardiovascular and metabolic risk.
Because it is a ratio, the unit cancels out — you can measure in centimetres or inches as long as both measurements use the same one.
Reading the risk band
The result places your ratio into a low, increased or high risk band using World Health Organization cut-offs, which differ by sex. The bar chart lines your ratio up against the increased- and high-risk thresholds so you can see where you stand.
For men, risk rises above 0.90 and is high from about 1.0; for women the corresponding points are roughly 0.85 and 0.95.
Measuring well
Small measurement errors shift the ratio, so be consistent:
- Measure the waist at its narrowest point, between the lowest rib and the hip bone.
- Measure the hips at the widest part of the buttocks.
- Keep the tape level and snug without compressing the skin.
- Stand relaxed and breathe out normally before reading.
Health note
WHR is a screening indicator, not a diagnosis. It is one of several measures of fat distribution and should be read alongside BMI, waist size and overall health. Consult a qualified professional before drawing conclusions about your cardiovascular risk.
Formula
WHR = waist / hip; men >0.90 or women >0.85 = increased riskFrequently asked questions
- Does the unit matter?
- No — because it is a ratio, you can use centimetres or inches as long as both measurements use the same unit.
