WHR for Men & Women
The threshold for high metabolic risk varies by biological sex due to fat distribution differences. The World Health Organization (WHO) establishes that high risk begins at a ratio of **0.90 or higher for men** and **0.85 or higher for women**.
Classification Shapes
WHR groups fat distribution profiles into three main shapes: **Apple** (central abdominal focus, high visceral fat), **Avocado** (balanced intermediate profile), and **Pear** (lower body hip/thigh focus, low cardiovascular risk).
Is WHR More Reliable Than BMI?
Yes, in many cases! Unlike BMI, which only evaluates total weight compared to height (misclassifying heavily muscular individuals), WHR isolates visceral fat—the highly active fat wrapping around organs that triggers diabetes and heart disease.

📏 The Mathematical Ratio
WHR is computed simply as the quotient of your waist circumference divided by your hip circumference:
WHR Index = Waist Circumference / Hip Circumference *Measurements can be in centimeters or inches, as long as units match.
🏥 Clinical Measurement Protocols
To guarantee diagnostic reliability, follow the World Health Organization (WHO) measurement standards:
- Waist: Measure at the midpoint between the lower margin of the last palpable rib and the top of the iliac crest (usually narrowest part).
- Hip: Measure around the widest portion of the buttocks, keeping the tape level.

Overview & Capabilities
Evaluate your body fat distribution and cardiovascular health risks with our Waist-to-Hip Ratio (WHR) Calculator! Recommended by the World Health Organization, WHR measures the ratio between waist and hip circumferences to identify visceral abdominal fat storage (Apple shape) versus gluteofemoral subcutaneous storage (Pear shape).

Frequently Asked Questions
Q How is the Waist-to-Hip Ratio calculated?
WHR = Waist Circumference / Hip Circumference. For example, a man with an 84 cm waist and 96 cm hips has a WHR of 84 / 96 = 0.875.
Q What are the WHO risk cutoffs for Waist-to-Hip Ratio?
For Men: Low Risk: ≤ 0.90; Moderate Risk: 0.91 – 0.99; High Risk: ≥ 1.00. For Women: Low Risk: ≤ 0.80; Moderate Risk: 0.81 – 0.84; High Risk: ≥ 0.85.
Q Why is visceral abdominal fat more dangerous than subcutaneous hip fat?
Visceral fat surrounds internal abdominal organs (liver, pancreas) and secretes inflammatory cytokines and free fatty acids directly into the portal circulation, increasing insulin resistance and arterial plaque.
