Waist-to-Hip Ratio Calculator

The waist-to-hip ratio (WHR) is a simple measurement that compares the circumference of your waist to that of your hips. The World Health Organization (WHO) recognizes WHR as a reliable indicator of abdominal obesity and a predictor of cardiovascular disease, type 2 diabetes, and other metabolic conditions. Unlike BMI, WHR specifically captures how fat is distributed across your body.

Quick Answer

A healthy waist-to-hip ratio is below 0.90 for men and below 0.85 for women according to WHO guidelines.

These results are estimates based on general formulas and are not a substitute for professional medical advice. Consult a healthcare provider before making health decisions.

Enter your measurements above to calculate your waist-to-hip ratio.

How the Formula Works

  1. Measure your waist circumference at the narrowest point of your torso, typically just above the navel. Use a flexible tape measure against bare skin.

  2. Measure your hip circumference at the widest point of your hips and buttocks.

  3. Ensure both measurements use the same unit (inches or centimeters).

  4. Divide your waist measurement by your hip measurement to get your WHR.

    WHR = waist circumference / hip circumference

  5. Compare the result against WHO risk categories for your sex to assess your health risk.

How to Interpret Your Results

The World Health Organization (WHO) defines waist-to-hip ratio thresholds that indicate health risk levels. These thresholds differ by sex because men and women naturally store fat in different areas. A higher WHR indicates more abdominal fat, which is associated with greater health risks regardless of overall body weight.

Low Risk (Male < 0.90, Female < 0.80)
0–0.79 — Your waist-to-hip ratio indicates a lower risk of weight-related health conditions.
Moderate Risk (Male 0.90-0.99, Female 0.80-0.85)
0.8–0.89 — Your waist-to-hip ratio suggests a moderate risk. Consider lifestyle improvements.
High Risk (Male >= 1.00, Female >= 0.86)
0.9–2 — Your waist-to-hip ratio indicates an elevated health risk. Consult a healthcare provider.

Limitations

  • WHR does not measure total body fat or distinguish between subcutaneous and visceral fat. Two people with the same WHR may have very different overall body compositions.
  • Measurement accuracy depends on consistent tape placement. Even small errors in waist or hip measurement can shift the ratio and change the risk category.
  • WHR thresholds may not apply equally to all ethnic groups, age ranges, or body types. Some populations have different risk profiles at the same WHR values.
  • WHR is a screening tool only and should not be used as a medical diagnosis. Always consult a qualified healthcare provider for personalized assessment.

Frequently Asked Questions

What is a healthy waist-to-hip ratio?
According to the WHO, a healthy WHR is below 0.90 for men and below 0.80 for women. Ratios above these thresholds indicate increasing levels of abdominal obesity and associated health risks such as cardiovascular disease and type 2 diabetes.
How do I measure my waist and hips correctly?
Measure your waist at the narrowest point of your torso, typically just above the navel. Measure your hips at the widest point of your buttocks. Stand relaxed, keep the tape horizontal and snug (but not compressing the skin), and measure against bare skin for best accuracy.
Is waist-to-hip ratio better than BMI?
WHR and BMI measure different things. BMI assesses overall weight relative to height but cannot distinguish muscle from fat or determine where fat is stored. WHR specifically measures abdominal fat distribution, which research shows is a stronger predictor of cardiovascular risk. Using both together provides a more complete picture.
Why are the risk thresholds different for men and women?
Men and women naturally store fat differently due to hormonal differences. Women tend to store more fat around the hips and thighs (gynoid pattern), while men tend to store more fat around the abdomen (android pattern). The different thresholds account for these biological differences in healthy fat distribution.
Can I lower my waist-to-hip ratio?
Yes. Reducing abdominal fat through regular aerobic exercise, strength training, and a balanced diet can improve your WHR over time. Reducing refined sugars and processed foods, managing stress, and getting adequate sleep also help decrease abdominal fat storage.
