Waist-to-Hip Ratio Calculator Guide
Calculate your waist-to-hip ratio (WHR), a simple measure of how fat is distributed around your body. It's one of several indicators researchers link to general health.
WHR = waist measurement ÷ hip measurement. Use the same unit for both. Measure the waist at its narrowest and the hips at their widest.
How Do I Calculate Waist-to-Hip Ratio?
Divide your waist measurement by your hip measurement. For example, a 32-inch waist and 40-inch hips give a ratio of 0.80. Lower ratios indicate more weight around the hips rather than the waist.
General Reference Ranges
The World Health Organization uses broad categories: for men, below 0.90 is lower risk; for women, below 0.85 is lower risk, with higher ratios linked to greater health risk in population studies. These are general references, not a diagnosis, and don't account for individual factors.
| Category | Men | Women |
|---|---|---|
| Lower risk | < 0.90 | < 0.80 |
| Moderate | 0.90–0.99 | 0.80–0.84 |
| Higher risk | ≥ 1.0 | ≥ 0.85 |
This is a general estimate for information only, not medical or nutritional advice. Individual needs vary with health, goals, and other factors — talk to a doctor or registered dietitian for guidance specific to you.

Frequently Asked Questions
What is a healthy waist-to-hip ratio?
Broadly, below 0.90 for men and below 0.85 for women is considered lower risk, but this is a general reference only.
How do I measure my waist and hips?
Measure the waist at its narrowest point and the hips at their widest, keeping the tape level and snug but not tight.
Is waist-to-hip ratio better than BMI?
Neither is complete; WHR reflects fat distribution while BMI reflects overall weight for height. They give different information.
Does this diagnose health problems?
No — it's an informational reference. A healthcare professional can interpret it alongside other measures.
