How This Is Calculated

Waist-to-height ratio (WHtR) compares your waist circumference to your height. Many researchers consider it a stronger predictor of health risk than BMI alone, since it accounts for where fat is carried.

The Formula

WHtR = waist circumference ÷ height, both measured in the same unit.

Below 0.40 is an underweight range, 0.40–0.49 is a healthy range, 0.50–0.59 is increased risk, and 0.60 and above is high risk. A simple rule of thumb: keeping your waist below half your height is associated with lower health risk.

Best used alongside other measurements.

This ratio doesn’t account for muscle mass or frame size. Pair it with waist-to-hip ratio or body fat percentage for more context.
