Hip Size Calculator – Guide & Formulas

Calculate your waist-to-hip ratio (WHR) and classify your body fat distribution shape (pear, apple, avocado) and health metrics.

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

  1. Select your biological sex and enter your height.
  2. Enter your waist circumference (measured just above the navel) and your hip circumference (measured at the widest point of the buttocks).
  3. Check your calculated Waist-to-Hip Ratio (WHR).
  4. Examine your body shape classification and associated health risk ranking.

The Formula

Waist-to-Hip Ratio (WHR) = Waist Circumference / Hip Circumference

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.

  1. Step 1: Set Waist = 28 in, Hips = 38 in.
  2. Step 2: Divide Waist by Hips: 28 / 38 ≈ 0.737.
  3. Step 3: Analyze: For females, a WHR under 0.80 is classified as "Low Risk" and indicates a healthy gynoid (pear) fat distribution.

Frequently Asked Questions

How do I measure my hips accurately?

Stand feet together, wrap a flexible measuring tape around the widest part of your hips and gluteal muscles. Keep the tape level with the floor, pull it snug, but not tight.

What are the World Health Organization (WHO) risk thresholds for WHR?

According to the WHO, abdominal obesity is defined as a Waist-to-Hip Ratio of 0.90 or higher for men, and 0.85 or higher for women. Ratios above these markers represent substantially elevated risks for heart disease and metabolic syndrome.
