What Is Waist-to-Hip Ratio?
Waist-to-Hip Ratio (WHR) is the ratio of your waist circumference to your hip circumference. It indicates how fat is distributed on your body, which matters significantly for health risk assessment. People who carry more weight around their midsection (apple-shaped) face higher risks of heart disease, type 2 diabetes, and metabolic syndrome compared to those who carry weight in their hips and thighs (pear-shaped). WHR is a simple, free measurement that provides health information beyond what BMI or weight alone can tell you.
How WHR Is Calculated
The formula is simply WHR = Waist Circumference / Hip Circumference. According to the World Health Organization, a WHR above 0.90 for men or above 0.85 for women indicates abdominal obesity and substantially increased health risk. A WHR below 0.80 for women and below 0.90 for men is considered low risk. Values between these thresholds indicate moderate risk.
How to Take Measurements
Measure your waist at the narrowest point between the bottom of your ribs and the top of your hip bones (usually at the navel level). Measure your hips at the widest point around your buttocks. Stand straight, breathe normally, and use a flexible measuring tape pulled snug but not compressing the skin. Take measurements on bare skin in the morning for consistency.
Frequently Asked Questions
Is WHR better than BMI?
WHR is better at predicting cardiovascular disease risk because it measures fat distribution, not just overall weight. However, BMI and WHR together provide the most complete picture. Use both for a comprehensive health assessment.
What is an ideal waist-to-hip ratio?
For men, below 0.90 is considered low risk. For women, below 0.80 is low risk. These thresholds are set by the World Health Organization based on cardiovascular disease research.
Can I change my waist-to-hip ratio?
Yes. Reducing caloric intake combined with regular exercise (both cardio and resistance training) preferentially reduces abdominal fat, improving your WHR over time. Spot reduction is a myth, but overall fat loss tends to come from the midsection first in many people.
