Put these formulas into practice with our instant, step-by-step Hip Size Calculator.
The Hip Size and Waist-to-Hip Ratio (WHR) Calculator measures your body fat distribution. It is used clinically to differentiate between an "apple" (android) shape—where fat is concentrated around the abdomen—and a "pear" (gynoid) shape—where fat is stored on the hips and thighs. The pear shape is associated with lower health risks, whereas the apple shape is a strong predictor of metabolic strain.
Key Takeaway
Use the free Hip Size Calculator to calculate your waist-to-hip ratio (whr) and classify your body fat distribution shape (pear, apple, avocado) and health metrics. Get instant results with step-by-step explanations.
How to Use the Hip Size Calculator
- Select your biological sex and enter your height.
- Enter your waist circumference (measured just above the navel) and your hip circumference (measured at the widest point of the buttocks).
- Check your calculated Waist-to-Hip Ratio (WHR).
- Examine your body shape classification and associated health risk ranking.
The Formula
Variable Definitions
- WHR: Waist-to-Hip Ratio, a metric used by the WHO to define abdominal obesity thresholds
- Hip Circumference: The maximum perimeter of the lower body, measured over the gluteal muscles
Determining WHR and Body Profile
A woman has a waist circumference of 28 inches and a hip circumference of 38 inches.
- Step 1: Set Waist = 28 in, Hips = 38 in.
- Step 2: Divide Waist by Hips: 28 / 38 ≈ 0.737.
- Step 3: Analyze: For females, a WHR under 0.80 is classified as "Low Risk" and indicates a healthy gynoid (pear) fat distribution.
