Waist to Height Ratio standards are based on research published in the WHO Bulletin, which recommends WHtR as a superior indicator of central obesity compared to BMI.
Waist-to-Height Ratio by Ethnicity
Compare health standards across major US ethnic groups
| Ethnic Group | Normal | Elevated | High Risk |
|---|---|---|---|
| Asian American | < 0.45 | 0.45 - 0.49 | ≥ 0.50 |
| White/Caucasian | < 0.50 | 0.50 - 0.54 | ≥ 0.55 |
| African American | < 0.50 | 0.50 - 0.54 | ≥ 0.55 |
| Hispanic/Latino | < 0.48 | 0.48 - 0.52 | ≥ 0.53 |
| Native American | < 0.50 | 0.50 - 0.54 | ≥ 0.55 |
These standards are based on CDC, WHO, and NIH research. Individual health assessments may vary. Consult a healthcare provider for personalized advice.

Understanding Waist-to-Height Ratio
What WHtR Measures
Waist-to-Height Ratio (WHtR) compares waist circumference to height. It is considered a better indicator of central obesity than BMI alone.
Cardiovascular Risk
WHtR of 0.5 or higher indicates increased risk of cardiovascular disease, diabetes, and hypertension. This threshold applies across all ages and ethnic groups.
Advantages Over BMI
WHtR accounts for body fat distribution, which is a better predictor of health risks than overall weight. It also eliminates the need for separate standards for different populations.
Monitoring Progress
Tracking WHtR over time can help monitor changes in abdominal fat, which is often more responsive to lifestyle changes than overall BMI.
