Waist-to-Hip Ratio Calculator

Both are useful and provide complementary information. Waist circumference alone predicts abdominal obesity regardless of height or hip size. WHR adds context about body shape - someone with a large waist but equally large hips may have a lower WHR than expected. Many cardiologists and endocrinologists use waist circumference as the primary metabolic risk marker and WHR as supporting context.

Yes, though it is uncommon. Building muscle in the hips and glutes while losing abdominal fat can improve WHR even with little or no change in total body weight - this is sometimes called body recomposition. Resistance training targeting the glutes and lower body alongside a slight caloric deficit can shift the ratio in the favorable direction over months of consistent training.

Yes. Visceral fat accumulation tends to increase with age, particularly after menopause in women (when the fat distribution pattern shifts from gynoid/pear toward android/apple shape) and gradually in men throughout adulthood. The WHO thresholds do not adjust for age, which means a WHR that was low-risk at 30 may approach moderate risk at 55 even with similar body weight.

Women naturally store more fat in the hips and gluteal region due to hormonal influences (estrogen promotes subcutaneous hip-and-thigh fat deposition). This means a healthy female naturally has a lower WHR than a healthy male at the same fitness level. Setting the female threshold lower (0.80 vs 0.90 for males) accounts for this physiological difference and avoids classifying women as high-risk for what is actually a healthy fat distribution pattern.
