Frequently Asked Questions about the Waist-to-Hip Ratio Calculator
What is a waist-to-hip ratio (WHR) and how is it different from BMI?
WHR divides waist by hip circumference to estimate fat distribution, while BMI uses weight and height to estimate total body mass. WHR captures central (visceral) fat, which BMI misses, so a person with a normal BMI can still have a high WHR and elevated cardiometabolic risk.
What is a healthy waist-to-hip ratio?
Per WHO 2008, low risk is below 0.90 for men and below 0.80 for women. Moderate risk is 0.90 to 0.99 (men) and 0.80 to 0.84 (women). Substantially increased risk starts at 1.00 (men) and 0.85 (women).
What is the difference between an apple-shaped and a pear-shaped body?
Apple means weight sits around the abdomen, giving a higher WHR. Pear means weight sits around hips and thighs, giving a lower WHR. Apple shapes are linked to higher risk of type 2 diabetes and cardiovascular disease.
How do I measure my waist and hips correctly?
Stand relaxed, breathe out, and use a soft tape. Measure the waist at the narrowest point between the lowest rib and the iliac crest, usually just above the navel. Measure the hips at the widest point around the buttocks. Keep the tape level and snug, not compressing the skin.
Does WHR work the same for all ages and ethnicities?
Not perfectly. WHO cut-offs are population averages and may under or overestimate risk for some Asian, South Asian, and older adult groups, where lower thresholds are sometimes used. Use WHR as one signal alongside BMI, waist circumference, and clinical advice.
