Waist-to-Height Ratio

Waist Circumference (cm)

Height (cm)

The WHtR is superior to BMI for measuring central obesity and predicting cardiovascular risk, as it remains accurate across different ethnicities and muscle mass profiles. Keep your waist to less than half your height.

Guidelines & Evidence

Verified

Last Review: 2026-07-17

When to Use

Screening for cardiometabolic risk (metabolic syndrome, type 2 diabetes, cardiovascular disease)

Evaluating central adiposity (visceral fat) more accurately than standard Body Mass Index (BMI)

Identifying "normal weight obese" individuals who have a normal BMI but high visceral fat

Tracking anthropometric changes during weight loss programs

Patient Population

Applicable to men, women, and children of all ethnicities. It is uniquely valuable because, unlike waist circumference alone, the ratio adjusts for the individual's stature, making a single cutoff value globally applicable.

How it Works

Formula

WHtR = Waist Circumference / Height (Both measurements must be in the same units: cm or inches)

Interpretation Thresholds

< 0.50	Healthy / Low Risk (Waist is less than half of height)
0.50 – 0.59	Increased Risk (Central obesity, increased risk for metabolic syndrome)
≥ 0.60	High Risk (Severe central obesity, highest cardiometabolic risk)
