Hers Index Calculator

The Hers Index Calculator helps determine body shape by calculating the ratio of hip circumference to waist circumference. This index is particularly useful for assessing female body proportions and identifying common body shape patterns.

Hers Index Calculation

Hers Index:

Where:
Hers Index = Hip Circumference ÷ Waist Circumference × 100
This value indicates body shape patterns:
• < 70: Typically considered "hourglass" shape
• 70-80: "Inverted triangle" shape
• 80-85: "Triangle" shape
• > 85: "Rectangle" shape

Body Shape Classification

Body shape will be determined after calculation

Hers Index Calculator Calculator Usage Guide

Learn how to use the Hers Index Calculator and understand its significance in body shape assessment

How to Use the Calculator

  1. Enter your waist circumference in centimeters (measure around the narrowest part of your waist)
  2. Enter your hip circumference in centimeters (measure around the widest part of your hips)
  3. Click the "Calculate" button to determine your Hers Index
  4. The calculator will display your Hers Index value and classify your body shape

Understanding the Hers Index Formula

The Hers Index is calculated using the following formula:

Hers Index = (Hip Circumference ÷ Waist Circumference) × 100

This ratio provides insights into your body proportions and helps identify common body shape patterns.

Interpreting Your Results

The Hers Index values typically fall into the following categories:

  • Hourglass shape (< 70): Balanced proportions with typically wider hips than waist
  • Inverted triangle shape (70-80): Wider hips than waist, often with a more defined lower body
  • Triangle shape (80-85): Wider waist than hips, creating an hourglass silhouette from the side
  • Rectangle shape (> 85): More uniform proportions, often appearing straighter from the side

Important Notes

The Hers Index is just one tool for body shape assessment and should be used as a reference rather than a definitive classification. Individual body variations exist, and factors like muscle tone, bone structure, and overall fitness also contribute to body shape.

For accurate measurements:

  • Measure in the morning before eating or exercising
  • Use a flexible measuring tape held horizontally around your body
  • Stand upright with feet together during measurement
