WHR · Singapore HPB / WHO Asia-Pacific
Waist-to-Hip Ratio Calculator
The BMI check that BMI misses. Waist-to-hip ratio measures abdominal fat distribution — a stronger predictor of cardiovascular risk than weight alone. Singapore uses lower thresholds than global guidelines.
What Your WHR Result Means
| Risk Level | Men (WHR) | Women (WHR) |
|---|---|---|
| Low risk | < 0.90 | < 0.80 |
| Moderate risk | 0.90–0.95 | 0.80–0.85 |
| High risk | > 0.95 | > 0.85 |

Why WHR Matters More Than BMI for Singaporeans
BMI alone cannot identify where fat is stored. Research consistently shows that visceral fat — fat surrounding internal organs in the abdominal cavity — is far more metabolically dangerous than subcutaneous fat stored elsewhere.
South Asian and Chinese Singaporeans in particular tend to accumulate visceral fat at lower overall BMI levels. A person with a “normal” BMI of 22 can still have an elevated WHR and carry meaningful cardiovascular risk. Checking both BMI and WHR together gives a much fuller picture of your health.
How to Measure Your Waist and Hip Correctly
Waist measurement
- 1.Stand upright, feet together
- 2.Measure at the narrowest point — usually halfway between your lowest rib and hip bone
- 3.Breathe out gently. Do not suck in or hold your breath
- 4.Keep the tape horizontal and snug (not tight)
Hip measurement
- 1.Stand upright with feet together
- 2.Measure at the widest point of your hips and buttocks
- 3.Keep the tape horizontal around the widest circumference
- 4.Measure in the morning before eating for consistency
Waist-to-Hip Ratio vs Waist Circumference Alone
Both WHR and waist circumference alone are valid predictors of cardiovascular risk. Singapore HPB recommends waist circumference targets of below 90 cm for men and below 80 cm for women. WHR adds context by comparing waist to hip size, which can reveal risk in people with larger frames.
High WHR is closely correlated with elevated blood pressure and cholesterol — two of the leading contributors to cardiovascular disease in Singapore. If your WHR is in the moderate or high risk range, a consultation with your GP or polyclinic is recommended.
Frequently Asked Questions
What is a healthy waist-to-hip ratio for Singaporeans?
Singapore HPB and WHO Asia-Pacific guidelines recommend a WHR below 0.90 for men and below 0.80 for women as low risk. Above 0.95 (men) and 0.85 (women) indicates high cardiovascular risk.
Why is waist-to-hip ratio important?
WHR measures central (abdominal) obesity — excess fat around the belly — which is more strongly linked to cardiovascular disease, diabetes, and metabolic syndrome than total body fat or BMI.
How does WHR compare to BMI?
BMI doesn't distinguish where fat is stored. Two people with the same BMI can have very different cardiovascular risk depending on fat distribution. WHR identifies abdominal obesity that BMI misses.
How do I reduce my waist-to-hip ratio?
Reduce overall body fat through a calorie deficit and regular aerobic exercise. Spot-reducing belly fat alone is not possible, but consistent exercise — especially cardio — preferentially reduces visceral abdominal fat.
