Waist-to-Hip Ratio Calculator
Your (WHR) compares the circumference of your waist to your hips. It is a quick way to gauge how your body fat distribution may affect your risk for heart disease, type 2 diabetes, and other conditions. A higher ratio indicates more fat stored around the abdomen, which is associated with greater health risk.

What Is Waist-to-Hip Ratio?
is a measurement that compares the circumference of your waist to the circumference of your hips. While tells you whether your overall weight is in a healthy range, WHR reveals where you carry your fat — and that distinction has significant implications for your health.
Research consistently shows that fat stored around the abdomen (visceral fat) is more metabolically active and more strongly associated with heart disease, type 2 diabetes, and stroke than fat stored in the hips and thighs. WHR is one of the simplest ways to assess whether your fat distribution pattern puts you at elevated risk.
The World Health Organization recognizes WHR as a reliable predictor of cardiovascular risk, and many clinicians use it alongside BMI and for a more complete health assessment.
How to Measure Correctly
Accurate results depend on consistent measuring technique. Follow these steps:
- Waist: Stand upright and breathe out naturally. Wrap a flexible tape measure around the narrowest part of your torso, typically just above the belly button and below the rib cage. The tape should be snug but not compressing the skin.
- Hips: Measure around the widest part of your buttocks. Keep the tape parallel to the floor and make sure it does not dip or ride up in the back.
- Calculate: Divide your waist measurement by your hip measurement. For example, a waist of 80 cm and hips of 100 cm gives a WHR of 0.80.
For the most reliable readings, measure at the same time of day (morning is ideal) and wear minimal clothing so the tape sits directly against your skin.
What Do the Results Mean?
The World Health Organization defines the following risk thresholds:
- Men: A WHR below 0.90 is considered low risk. A ratio of 0.90 to 0.99 indicates moderate risk, and 1.00 or above indicates high risk.
- Women: A WHR below 0.80 is considered low risk. A ratio of 0.80 to 0.84 indicates moderate risk, and 0.85 or above indicates high risk.
Higher ratios suggest a greater proportion of abdominal fat, which is linked to increased insulin resistance, elevated blood pressure, and unfavorable cholesterol profiles.
WHR vs. BMI: Which Is Better?
Neither metric is perfect on its own. BMI assesses total body weight relative to height but cannot distinguish between fat and muscle or tell you where fat is stored. WHR specifically targets fat distribution but says nothing about your overall weight. Studies have found that WHR is a stronger predictor of heart attack risk than BMI in many populations — particularly for individuals whose BMI falls in the normal range but who carry excess abdominal fat.
The best approach is to use both metrics together for a well-rounded assessment.
Tips for Improving Your WHR
- Reduce refined carbohydrates and added sugars, which are closely linked to abdominal fat accumulation.
- Include regular cardiovascular exercise — brisk walking, cycling, or swimming — to target visceral fat.
- Add resistance training to build muscle in the hips and glutes, which can improve the ratio from both sides of the equation.
- Manage stress and prioritize sleep. Elevated cortisol levels promote fat storage around the midsection.
