Waist-to-Hip Ratio
Assess health risk based on fat distribution pattern
What This Calculator Measures
The Waist-to-Hip Ratio (WHR) is a measure of body fat distribution that indicates cardiovascular and metabolic health risk. Central (abdominal) fat is more strongly correlated with health risks than peripheral fat, making WHR a more useful health indicator than BMI for many people.
How It Works
**WHR = Waist Circumference / Hip Circumference**
Measure your waist at the narrowest point (usually at the navel) and your hips at the widest point of the buttocks.
Male Risk Categories
| WHR | Risk Level |
|---|---|
| Below 0.90 | Low risk |
| 0.90 - 0.99 | Moderate risk |
| 1.00+ | High risk |
Female Risk Categories
| WHR | Risk Level |
|---|---|
| Below 0.80 | Low risk |
| 0.80 - 0.85 | Moderate risk |
| 0.85+ | High risk |
Why It Matters
A higher WHR indicates more visceral (abdominal) fat, which is associated with increased risk of cardiovascular disease, type 2 diabetes, and metabolic syndrome. Research consistently shows WHR is a better predictor of cardiovascular events than BMI alone.
