Waist Hip Ratio Calculator

Where you carry your weight matters as much as how much you weigh. Waist-to-hip ratio divides your waist circumference by your hip circumference, and the result reveals fat distribution: fat stored around the belly (apple-shaped) tracks with higher cardiovascular and metabolic risk than fat stored around the hips and thighs (pear-shaped). The World Health Organization flags ratios above 0.90 for men and 0.85 for women as elevated risk.

A woman in Miami measuring 32 inches at the waist and 39 at the hips gets a ratio of about 0.82 — under the 0.85 threshold, suggesting lower-risk fat distribution even if her BMI is unremarkable. The calculator also converts both measurements to inches for Americans reaching for a standard tape measure, since the inputs accept centimeters. Measure the waist at the narrowest point (or the navel, consistently) and the hips at the widest point of the buttocks.

This is a risk-screening ratio, not a diagnosis, and it says nothing about fitness or muscle. Pregnant women and people with significant abdominal bloating will get misleading numbers. Pair it with blood pressure, cholesterol, and blood sugar — the full picture your doctor actually uses.
