Calculate your Waist-to-Hip Ratio
The waist-to-hip ratio (WHR) is calculated by dividing your waist circumference by your hip circumference. For example, a 32-inch waist and 40-inch hips gives a WHR of 0.80.
According to the WHO, WHR is a better predictor of cardiovascular disease risk than BMI alone. It measures fat distribution, and abdominal fat is more strongly associated with health risks than fat elsewhere.
Results are categorized by gender: for men, a WHR below 0.90 is low risk; for women, below 0.80. Higher ratios indicate more abdominal fat and increased cardiovascular and metabolic health risks.
Measure at the narrowest point of your waist and the widest part of your hips. Take measurements in the morning before eating for consistency. Use a flexible tape measure and stand relaxed without sucking in.
A healthy waist-to-hip ratio differs by gender. For men, a ratio below 0.90 indicates low health risk, 0.90-0.99 is moderate risk, and 1.0 or above is high risk. For women, below 0.80 is low risk, 0.80-0.84 is moderate risk, and 0.85 or above is high risk. These thresholds are based on World Health Organization guidelines and are associated with cardiovascular disease, type 2 diabetes, and metabolic syndrome risk.
For the waist measurement, wrap a flexible tape measure around the narrowest part of your torso, typically at or just above your navel. For the hip measurement, measure at the widest point of your buttocks. Stand relaxed with your feet together. Keep the tape snug but not tight, and ensure it is level all the way around. Measure against bare skin or over thin clothing. Take measurements in the morning before eating for consistency, and take two or three readings to ensure accuracy.
BMI (Body Mass Index) is a ratio of weight to height that classifies overall weight status but does not indicate where fat is stored. Waist-to-hip ratio (WHR) specifically measures fat distribution, telling you whether you carry more fat around your abdomen or hips. Research shows WHR is a better predictor of cardiovascular disease and metabolic health than BMI alone, because abdominal (visceral) fat is more metabolically active and harmful than fat stored in the hips and thighs. Using both measurements together provides a more complete health picture.
