How It Works
What is Waist-to-Hip Ratio?
Waist-to-hip ratio (WHR) is a simple measurement that compares the circumference of your waist to the circumference of your hips. It's calculated by dividing your waist measurement by your hip measurement. This ratio is used as an indicator of body fat distribution and potential health risks associated with excess abdominal fat.
How to Measure
For accurate results, follow these measurement guidelines:
- •Waist: Measure around the narrowest part of your waist, typically just above your belly button. Stand relaxed and breathe normally.
- •Hips: Measure around the widest part of your hips and buttocks. Keep your feet together and measure at the fullest point.
- •Tips: Use a flexible measuring tape, keep it level and snug (not tight), and take measurements while standing.
Understanding the Calculation
The formula is straightforward:
WHR = Waist Circumference ÷ Hip Circumference For example, if your waist measures 80 cm and your hips measure 100 cm, your WHR would be 0.80 (80 ÷ 100 = 0.80).
Health Risk Categories
The World Health Organization (WHO) uses WHR to assess health risk based on abdominal obesity:
Low Risk
Males: WHR ≤ 0.95
Females: WHR ≤ 0.80
Moderate Risk
Males: 0.96 - 1.0
Females: 0.81 - 0.85
High Risk
Males: WHR > 1.0
Females: WHR > 0.85
Why It Matters
Waist-to-hip ratio is an important health indicator because it reveals how fat is distributed in your body:
- •Apple Shape (Higher WHR): More fat around the waist (visceral fat) is associated with increased risk of cardiovascular disease, type 2 diabetes, and metabolic syndrome.
- •Pear Shape (Lower WHR): More fat around the hips and thighs (subcutaneous fat) is generally associated with lower health risks.
Important Note: WHR is a useful screening tool but should be considered alongside other health metrics like BMI, body fat percentage, blood pressure, and cholesterol levels. Individual health varies, and this calculator should not replace professional medical evaluation.

Frequently Asked Questions
What does waist-to-hip ratio tell me about my health?
WHR indicates body fat distribution patterns. Higher ratios (apple shape) indicate more abdominal fat, which is associated with increased risk of heart disease, type 2 diabetes, and metabolic syndrome. Lower ratios (pear shape) indicate fat stored in hips and thighs, which carries lower health risks.
How do I measure waist and hip circumference correctly?
Waist: Measure around the narrowest point, typically just above the belly button. Hip: Measure around the widest part of your buttocks. Stand relaxed with feet together, breathe normally, and keep the tape parallel to the floor. Take 2-3 measurements and use the average.
What's a healthy WHR range?
For men, low risk is below 0.90, moderate risk is 0.90-0.99, and high risk is 1.0+. For women, low risk is below 0.80, moderate risk is 0.80-0.84, and high risk is 0.85+. These thresholds are based on research linking WHR to cardiovascular and metabolic health risks.
Can I improve my WHR?
Yes! Regular cardiovascular exercise, strength training, and a balanced diet can help reduce abdominal fat and improve WHR. Targeting belly fat specifically isn't possible, but overall fat loss tends to reduce abdominal fat proportionally more. Consult a healthcare provider or fitness professional for personalized guidance.
