What Is Waist-to-Hip Ratio?

Waist-to-hip ratio (WHR) compares the circumference of your waist to your hips to estimate where your body stores fat. Because abdominal ("apple-shaped") fat is more strongly linked to cardiovascular and metabolic risk than fat stored around the hips and thighs ("pear-shaped"), WHR is used by the World Health Organization as a simple screening tool alongside BMI.

Waist-to-Hip Ratio = Waist Circumference ÷ Hip Circumference

❓ Frequently Asked Questions

What's considered a healthy waist-to-hip ratio?
The WHO generally considers a WHR below 0.90 for men and below 0.80 for women to indicate lower cardiometabolic risk, though this is one screening tool among several, not a full diagnosis.
Is waist-to-hip ratio better than BMI?
Neither is perfect alone. BMI doesn't distinguish where fat is stored, while WHR specifically flags abdominal fat, which research links more directly to heart disease and type 2 diabetes risk — many clinicians use both together.
Why does fat location matter for health risk?
Visceral (abdominal) fat surrounds internal organs and is metabolically active in ways that increase inflammation and insulin resistance, whereas fat on the hips and thighs is considered comparatively lower-risk.
How often should I re-measure?
Monthly is plenty for tracking body composition changes over time — day-to-day measurements can fluctuate slightly with bloating, hydration, and measurement technique.
Can waist-to-hip ratio diagnose a health condition?
No — it's a screening estimate, not a diagnostic test. Speak with a healthcare provider for a complete cardiometabolic risk assessment.
