What is Waist-to-Height Ratio?

Waist-to-Height Ratio (WHtR) compares your waist circumference to your height to estimate central (abdominal) body fat, which many researchers consider a stronger predictor of cardiometabolic risk than BMI alone.

Because it accounts for where fat is carried rather than just overall weight, WHtR can flag elevated risk even in people whose BMI falls in a "healthy" range.

How is Waist-to-Height Ratio calculated?

Divide your waist circumference by your height, measured in the same units. The result is a simple ratio — a widely cited rule of thumb is keeping your waist circumference below half your height.

Formula

WHtR = waist circumference ÷ height (same units)

Example: 32 in waist ÷ 68 in height = 0.47

Category	Range
Healthy range	Below 0.5
Increased risk	0.5 – 0.6
High risk	Above 0.6
