Waist to Hip Ratio Calculator

Per WHO guidelines, a WHR below 0.80 is considered low risk for women. A ratio between 0.80 and 0.85 is moderate risk. A ratio above 0.85 is high risk and associated with significantly increased likelihood of cardiovascular disease, type 2 diabetes, and metabolic syndrome.

For men, a WHR below 0.90 is low risk. A ratio between 0.90 and 0.99 is moderate risk. A ratio of 1.00 or above is high risk. These thresholds come from WHO and NIH research linking central obesity to metabolic and cardiovascular disease.

Stand straight and exhale normally. Find the narrowest point of your torso, usually about one inch above your belly button. Wrap a flexible tape measure around your bare waist at that point, keeping the tape parallel to the floor. Record the measurement in centimeters or inches - just be consistent between waist and hip measurements.

Stand with feet together. Find the widest part of your hips and buttocks, usually at or just below the hip bones. Wrap the tape measure around that widest point, parallel to the floor. The tape should be snug but not compressing the skin.

Apple shape (also called android or central obesity) describes people who carry most of their fat around the abdomen, producing a higher WHR. Pear shape (gynoid) describes fat stored primarily in the hips and thighs, producing a lower WHR. Apple-shaped fat distribution around the organs is more metabolically harmful than pear-shaped subcutaneous fat.

Research published in The Lancet and other journals shows WHR is a stronger predictor of cardiovascular events than BMI in many populations. BMI cannot distinguish between fat and muscle, or between central and peripheral fat. WHR specifically captures abdominal obesity, which is the metabolically dangerous type. Using both gives a fuller picture.

Multiply your hip circumference by 0.80 (for women) or 0.90 (for men) to find your maximum healthy waist measurement. For example, a woman with 100 cm hips should aim for a waist below 80 cm. Use the Ideal Waist Finder tab in this calculator to get your specific target range instantly.

Yes. Aerobic exercise and a calorie deficit both reduce visceral (abdominal) fat, which lowers the waist measurement faster than the hip measurement, bringing the WHR down over time. Studies show that even a 5 to 10 percent reduction in body weight significantly improves WHR in overweight individuals.

Women naturally store more fat in the hip and thigh area due to hormonal differences (estrogen promotes peripheral fat storage). This means women tend to have lower WHRs than men at similar levels of fitness. The WHO uses sex-specific thresholds to account for this biological difference and provide clinically relevant risk cutoffs for each group.

An hourglass figure typically corresponds to a WHR around 0.70 to 0.75 for women, which is also within the ideal low-risk zone. This body shape has historically been associated with higher estrogen levels and lower cardiovascular risk. However, body shape is partly genetic and influenced by bone structure, not just fat distribution.

Yes. As people age, fat tends to redistribute toward the abdominal area even without significant total weight gain, raising WHR. Post-menopausal women in particular often see WHR increase as estrogen levels drop and fat storage shifts from peripheral to central locations. This is one reason cardiovascular risk rises in women after menopause.

Waist circumference alone is a useful measure of abdominal obesity, but it does not account for body frame size. Two people with the same waist circumference but very different heights or hip sizes have different risk profiles. WHR normalizes waist size against hip size, providing a ratio that is more consistent across body frames.
