Your waist-to-hip ratio (WHR) is interpreted using WHO thresholds that differ by sex. For men, a WHR below 0.90 indicates low cardiovascular risk, while 0.90–0.99 suggests moderate risk and 1.0 or above indicates substantially increased risk. For women, a WHR below 0.80 is low risk, 0.80–0.84 is moderate, and 0.85 or above signals substantially increased risk of cardiovascular disease, type 2 diabetes, and metabolic syndrome.

A higher WHR indicates a greater proportion of fat stored around the abdomen (apple-shaped body) compared to the hips and thighs (pear-shaped body). Abdominal or visceral fat is more metabolically active and secretes inflammatory cytokines that contribute to insulin resistance, dyslipidemia, and atherosclerosis. This is why WHR is a stronger predictor of cardiovascular events than overall body weight in many studies.

Use this calculator as a complement to BMI when assessing cardiovascular and metabolic risk. WHR is particularly valuable in cases where BMI may be misleading — for instance, in individuals who are of normal weight by BMI but carry excess abdominal fat (sometimes called metabolically obese normal weight, or MONW). It is also useful for patients who are overweight by BMI but carry fat predominantly in their hips and thighs, which carries less cardiovascular risk.

Clinicians frequently use WHR in metabolic syndrome screening, diabetes risk assessment, and cardiovascular disease prevention programs. It is also a practical tool for tracking the effectiveness of exercise programs that target visceral fat reduction, as WHR may improve even when overall weight remains stable.

WHR does not measure visceral fat directly — it infers fat distribution from external circumference measurements. Two individuals with the same WHR may have different amounts of visceral versus subcutaneous abdominal fat. For direct visceral fat quantification, imaging methods such as CT or MRI are required.

Measurement technique matters significantly. The waist should be measured at the narrowest point between the ribs and the iliac crest (or at the navel level, depending on the protocol used), and the hips at the widest point of the buttocks. Inconsistent landmarking can produce unreliable results. Additionally, WHR does not account for overall body size — a very thin person and a very heavy person could have the same ratio despite vastly different health profiles. For this reason, WHR is best used alongside other metrics such as BMI, waist circumference alone, and body fat percentage.
