Free Waist-to-Hip Ratio Calculator - Health Risk

Q: What is a healthy waist-to-hip ratio?

A healthy waist-to-hip ratio is below 0.90 for men and below 0.80 for women. Ratios above these thresholds indicate increased health risks, particularly for cardiovascular disease and type 2 diabetes.

Q: How do I measure my waist?

Measure your waist at the narrowest point, typically just above the belly button. Use a flexible tape measure and ensure it is snug but not compressing the skin. Breathe out normally before taking the measurement.

Q: Is WHR better than BMI?

WHR can be a better indicator of health risk than BMI because it specifically measures fat distribution. While BMI only considers total weight and height, WHR identifies abdominal obesity, which is a stronger predictor of cardiovascular disease.

Q: What does a high WHR risk mean?

A high WHR means you carry more fat around your abdomen compared to your hips. This 'apple-shaped' pattern is associated with higher risks of heart disease, stroke, type 2 diabetes, and certain cancers.

Q: Can WHR improve with exercise?

Yes, regular exercise combined with a healthy diet can reduce waist circumference more than hip size, thereby improving your WHR. Aerobic exercise and core strengthening are particularly effective at targeting abdominal fat.

Q: Does waist size matter more than weight?

Research suggests that waist circumference is a stronger predictor of health risks than total body weight or BMI. Two people can weigh the same but have very different health profiles depending on where they carry their fat.

What Is Waist-to-Hip Ratio?

Waist-to-hip ratio (WHR) is a simple measurement that compares the circumference of your waist to that of your hips. It is calculated by dividing your waist measurement by your hip measurement. Unlike BMI, which only considers total body weight and height, WHR provides insight into how fat is distributed across your body. This matters because where you carry fat has a significant impact on your overall health risk.

The World Health Organization recognizes WHR as an important indicator of central obesity and uses it alongside BMI to assess health risks. A higher ratio indicates more abdominal fat, which is linked to a greater likelihood of developing serious health conditions.

Why WHR Matters for Health

Men < 0.90

Low Risk

Men 0.90 – 0.99

Moderate Risk

Men ≥ 1.0

High Risk

Women < 0.80

Low Risk

Women 0.80 – 0.89

Moderate Risk

Women ≥ 0.90

High Risk

Research consistently shows that people with a higher WHR have elevated risks of cardiovascular disease, type 2 diabetes, and certain cancers. Even if your overall weight is within a healthy range, excess abdominal fat can still pose significant health threats. WHR helps doctors and health professionals identify these hidden risks that BMI alone might miss.

How to Measure Correctly

To get an accurate WHR, measure both your waist and hips using a flexible tape measure. For your waist, find the narrowest point of your torso, typically just above your belly button. Breathe out naturally and wrap the tape around this point without pulling it tight.

For your hips, measure at the widest point of your buttocks with your feet together. Keep the tape parallel to the floor and ensure it is level all the way around. Divide your waist measurement by your hip measurement to get your WHR. Use our Learn about WHR methodology for instant results.

Avoid sucking in your stomach — relax and measure at the end of a normal exhale.
Use the same tape for both measurements for consistency.
Measure in the morning before eating for the most accurate reading.
