Calculate your Waist-to-Hip Ratio (WHR), determine body fat distribution, evaluate obesity-related health risks, and understand your cardiovascular risk based on World Health Organization (WHO) guidelines.
This calculator determines your Waist-to-Hip Ratio (WHR) by dividing your waist circumference by your hip circumference. It evaluates body fat distribution using World Health Organization (WHO) recommendations and estimates obesity-related health risks such as cardiovascular disease, type 2 diabetes, and metabolic syndrome.
Measure your waist at its narrowest point or just above your belly button.
Measure the widest part of your hips while standing naturally.
The calculator divides your waist circumference by your hip circumference to calculate your Waist-to-Hip Ratio.
Your WHR is compared with WHO guidelines to determine body fat distribution and health risk.
The Waist-to-Hip Ratio (WHR) is a simple yet highly effective measurement used to assess how body fat is distributed around your body. It compares the circumference of your waist to the circumference of your hips, providing valuable insight into abdominal fat accumulation and the potential risk of developing chronic diseases.
Unlike body weight alone, WHR focuses on where fat is stored. Excess fat around the abdomen is strongly associated with cardiovascular disease, type 2 diabetes, hypertension, metabolic syndrome, and certain cancers. Because of this, organizations such as the World Health Organization (WHO) recommend using Waist-to-Hip Ratio alongside Body Mass Index (BMI) for a more complete health assessment.
A lower WHR generally indicates healthier fat distribution, while a higher WHR suggests greater abdominal fat and increased health risks.
WHR = Waist Circumference ÷ Hip Circumference
For example, if your waist measures 80 cm and your hips measure 100 cm, your Waist-to-Hip Ratio is:
80 ÷ 100 = 0.80
This value is then compared with WHO guidelines to determine your health risk category.
The World Health Organization classifies Waist-to-Hip Ratio differently for men and women because body fat distribution naturally differs between genders.
| Risk Level | Men | Women |
|---|---|---|
| Low Risk | < 0.90 | < 0.80 |
| Moderate Risk | 0.90–0.99 | 0.80–0.84 |
| High Risk | ≥ 1.00 | ≥ 0.85 |
| BMI | WHR |
|---|---|
| Measures body weight relative to height. | Measures body fat distribution. |
| Does not identify abdominal fat. | Highlights abdominal obesity. |
| Useful for general weight status. | Better predictor of cardiovascular risk. |
If your Waist-to-Hip Ratio falls into the high-risk category, or if you also have obesity, diabetes, high blood pressure, or elevated cholesterol, consult a healthcare professional for a comprehensive health assessment. A high WHR is an indicator of increased health risk but is not a diagnosis by itself. Regular monitoring, lifestyle improvements, and professional guidance can significantly reduce your long-term risk of cardiovascular and metabolic diseases.
This Waist-to-Hip Ratio (WHR) Calculator is intended for educational and informational purposes only. It estimates body fat distribution using internationally recognized guidelines from the World Health Organization (WHO). The results should not be used to diagnose or treat any medical condition. Always consult a qualified healthcare professional for personalized medical advice, diagnosis, or treatment.
According to WHO guidelines, a healthy WHR is generally below 0.90 for men and below 0.80 for women. Lower values generally indicate healthier body fat distribution.
WHR helps estimate abdominal fat distribution, which is closely linked to cardiovascular disease, diabetes, metabolic syndrome, and other chronic health conditions.
WHR and BMI measure different aspects of health. BMI estimates overall body weight relative to height, while WHR measures fat distribution. Using both together provides a more complete assessment.
Measuring every 4 to 8 weeks is usually sufficient when monitoring changes from diet, exercise, or weight loss programs.
Yes. Regular cardiovascular exercise, strength training, and a healthy diet can reduce abdominal fat and improve your Waist-to-Hip Ratio over time.
Yes. Men and women naturally store body fat differently, which is why WHO uses different WHR classifications for each gender.
You can use centimeters or inches, as long as both waist and hip measurements use the same unit.
Common causes include abdominal obesity, physical inactivity, poor diet, aging, hormonal changes, genetics, and certain medical conditions.
A high WHR is associated with increased risk of cardiovascular disease, hypertension, type 2 diabetes, and metabolic syndrome, but it is not a diagnostic test.
This calculator is designed primarily for adults. Children and adolescents should be evaluated using age- and sex-specific growth charts and clinical guidance.
