Body fat distribution risk — measurements in any unit.
WHR = W ÷ H
The waist-to-hip ratio is calculated by simply dividing the waist circumference by the hip circumference. Both measurements must be in the same unit (either both in centimetres or both in inches). The resulting ratio is a dimensionless number used to classify cardiovascular and metabolic health risk according to World Health Organization thresholds.
WHR = 76 ÷ 98 = 0.776... → rounded to two decimal places: **0.78**
Result: WHR = 0.78
A WHR of 0.78 for a woman falls in the low-risk category according to WHO guidelines (below 0.80). This suggests that body fat is distributed more in the hips and thighs (gynoid pattern) rather than the abdomen, which is associated with lower cardiovascular and metabolic disease risk. Had the same woman measured a WHR above 0.85, she would be classified as high risk, indicating a higher likelihood of conditions such as type 2 diabetes, hypertension, and coronary heart disease.

Total body weight and BMI do not tell the whole story about health risk. Research consistently shows that where fat is stored matters as much as how much fat you carry. Visceral fat — stored deep in the abdomen around internal organs — is metabolically active and releases inflammatory markers and free fatty acids that increase the risk of cardiovascular disease, insulin resistance, and type 2 diabetes.
BMI (Body Mass Index) measures overall body size relative to height but cannot distinguish between muscle mass and fat mass, or between central (abdominal) and peripheral fat distribution. WHR directly captures abdominal obesity and is considered a stronger predictor of cardiovascular risk in many population studies. The WHO recommends using both measures together for a more complete picture.
| Risk Level | Women (WHR) | Men (WHR) | |---|---|---| | Low risk | < 0.80 | < 0.90 | | Moderate risk | 0.80 – 0.85 | 0.90 – 0.95 | | High risk | > 0.85 | > 0.95 |
WHR is a useful screening tool but has limitations: it does not account for height, bone structure, age-related fat redistribution, or ethnicity-specific risk thresholds (some guidelines use lower cut-offs for Asian populations). It should always be interpreted alongside clinical findings and a healthcare professional's judgment.
A WHR above 1.0 means your waist is larger than your hips, indicating significant central (abdominal) obesity. This is associated with substantially elevated risk of type 2 diabetes, hypertension, stroke, and coronary artery disease. It is advisable to consult a healthcare professional.
Yes. Some health authorities and researchers recommend lower WHR cut-offs for South Asian, East Asian, and Southeast Asian populations because abdominal fat tends to accumulate at lower overall body weight in these groups, leading to higher cardiometabolic risk at lower WHR values compared to European populations.
WHR is primarily validated for adults. For children and adolescents, age- and sex-specific percentile charts for waist circumference are typically more appropriate. Consult a paediatrician or use paediatric-specific tools for health assessment in young people.
Reducing visceral fat through a combination of aerobic exercise, resistance training, and a calorie-controlled diet rich in whole foods can decrease waist circumference. Hip and gluteal muscle development through resistance training can also increase hip circumference, improving the ratio from both directions.
According to the World Health Organization, a WHR below 0.80 is considered low risk for women. A ratio between 0.80 and 0.85 is moderate risk, and above 0.85 is high risk for cardiovascular and metabolic disease.
For men, the WHO classifies a WHR below 0.90 as low risk, 0.90–0.95 as moderate risk, and above 0.95 as high risk. Values above 1.0 indicate significant abdominal obesity.
You can use either unit, as long as both the waist and hip measurements are in the same unit. The ratio is dimensionless, so the result will be identical whether you use cm or inches consistently.
Both have value. WHR is generally considered a better predictor of cardiovascular risk because it captures fat distribution, whereas BMI only reflects overall body size. Many clinicians and researchers recommend using both together.
For general health monitoring, measuring every 3–6 months is reasonable, especially if you are tracking the effects of dietary or exercise changes. Avoid measuring right after a large meal or heavy exercise, which can temporarily affect measurements.
Yes. Fat distribution naturally shifts toward the abdomen with age, particularly after menopause in women, which can increase WHR even without significant weight gain. This is one reason WHR monitoring is particularly relevant for adults over 40.
