Have you ever noticed two people with the same weight but very different waistlines? That simple difference in shape—the waist-to-hip ratio—can reveal important clues about health risks.
The waist-to-hip ratio (WHR) is your waist circumference divided by your hip circumference. The World Health Organization expert consultation recommends a healthy WHR of 0.90 or below for men and 0.85 or below for women (World Health Organization, 2011). Understanding your WHR provides insights into fat distribution and associated risks for heart disease and diabetes.
Mastering the measurement and meaning of your WHR empowers you to track changes over time and take informed steps to manage your health proactively.
Calculate Your Waist-to-Hip Ratio
- Measure your waist circumference at the midpoint between your lowest rib and the top of your hip bone. Use a flexible, non-stretch tape measure and record the measurement at the end of a normal exhale.
- Measure your hip circumference around the widest part of your buttocks, keeping the tape parallel to the floor.
- Ensure both measurements use the same units (inches or centimeters).
- Divide waist circumference by hip circumference to calculate your WHR.

Interpreting Your WHR Results
| WHR Range | Risk Level | Group |
|---|---|---|
| ≤ 0.90 | Healthy | Men |
| > 0.90 | Substantially increased risk of metabolic complications | Men |
| ≤ 0.85 | Healthy | Women |
| > 0.85 | Substantially increased risk of metabolic complications | Women |
Higher WHR is associated with increased total and cardiovascular mortality, most consistently in men (Cho et al., 2024).
Why WHR Matters
Unlike body mass index, WHR reflects fat distribution more precisely. Central adiposity—the “apple” shape—indicates excess visceral fat around organs, which releases inflammatory substances that raise cholesterol and blood pressure (Battineni et al., 2021).
A large-scale study of 387,672 adults found WHR to be a stronger predictor of all-cause mortality than BMI (Khan et al., 2023).
In clinical research on coronary artery disease patients, women with higher WHR had a nearly twofold increased risk of major adverse cardiovascular events, even after adjusting for BMI (Medina-Inojosa et al., 2018).
WHR vs. Other Body Composition Metrics
Combining WHR with metrics like BMI and waist-to-height ratio provides a more comprehensive view of body composition. Explore our Body Fat Percentage Calculator or read about visceral vs. subcutaneous fat.
How BodySpec DEXA Scans Complement WHR Assessment
A BodySpec DEXA scan measures total fat mass, lean mass, and bone density with clinical accuracy, including precise visceral fat quantification. While WHR efficiently screens for central adiposity, DEXA reveals regional body composition down to individual tissue layers, guiding targeted interventions and tracking progress over time.
Ready to compare your WHR alongside a detailed body composition profile? Book your BodySpec DEXA scan today to uncover precise insights into your fat distribution, muscle mass, and bone health.
Conclusion
Calculating your waist-to-hip ratio is a simple, evidence-backed way to assess fat distribution and potential health risks. Whether you use it for personal fitness tracking or clinical screening, WHR uncovers insights that scale weight and BMI can miss. Pairing this quick measure with a BodySpec DEXA scan delivers a complete view of your body composition, empowering smarter decisions for health and performance.
