WHR Calculator - Waist-to-Hip Ratio
Calculate your Waist-to-Hip Ratio (WHR) to assess body fat distribution and risk of cardiovascular and metabolic diseases.

Calculate WHR
What is Waist-to-Hip Ratio (WHR)?
The Waist-to-Hip Ratio (WHR) is an anthropometric indicator that assesses body fat distribution. It is calculated by dividing waist circumference by hip circumference. Elevated values indicate abdominal fat accumulation (android obesity), associated with higher risk of cardiovascular diseases, type 2 diabetes, and metabolic syndrome.
How to measure correctly
Waist: measure at the narrowest part of the abdomen, usually at navel height, with the tape measure positioned horizontally. Hip: measure at the widest part of the buttocks, keeping the tape parallel to the floor. Take measurements standing, relaxed, after exhaling normally. For men, WHR < 0.90 is ideal; for women, < 0.80. Values above 1.0 (men) or 0.85 (women) indicate high risk.
Limitations and Considerations
WHR is a screening tool, not replacing complete medical evaluation. It doesn't consider muscle mass, bone density, or detailed body composition. Athletes and very muscular people may have altered values without elevated risk. Pregnant women, children, and adolescents require specific parameters. Combine WHR with BMI, isolated waist circumference, and laboratory tests for complete cardiometabolic risk assessment.
Frequently Asked Questions about WHR
What's the difference between WHR and waist circumference?
Isolated waist circumference already indicates risk (>102cm men, >88cm women), while WHR relativizes this value in relation to the hip, indicating the pattern of fat distribution. Both are useful: isolated waist is simpler, WHR may be more specific for some cases.
Does high WHR mean I'm obese?
Not necessarily. High WHR indicates android fat distribution (abdominal accumulation), even in people with normal weight. It's possible to have normal BMI but elevated WHR, a situation called 'metabolically obese normal weight', which still confers cardiovascular risk.
How to reduce WHR?
Reduce abdominal fat through balanced hypocaloric diet, regular aerobic exercise (150min/week), strength training, stress reduction, adequate sleep (7-9h/night), and cortisol control. Abdominal fat responds well to lifestyle changes, but genetics also influence.
Does WHR vary with age?
Yes. With aging, there's a tendency for abdominal fat accumulation and loss of hip muscle mass, increasing WHR. Therefore, maintaining physical activity and muscle mass throughout life is essential to prevent this increase and its associated risks.
