How to Calculate: The Waist to Hip Ratio Calculator Formula
Calculates the ratio between abdominal fat and pelvic width to identify android (apple) vs gynoid (pear) body fat distribution.
Step-by-Step Calculation Guide
- Select biological sex.
- Measure waist circumference at the narrowest point or midway between lowest rib and iliac crest.
- Measure hip circumference at the widest portion of the buttocks.
- Inspect your calculated WHR and WHO cardiovascular risk classification.

World Health Organization (WHO) WHR Risk Classification
Official reference values and benchmark classifications based on standard institutional guidelines.
| Health Risk Category | Men (WHR) | Women (WHR) | Fat Distribution Pattern |
|---|---|---|---|
| Low Risk | 0.90 or less | 0.80 or less | Gynoid (Pear) shape, subcutaneous hip fat |
| Moderate Risk | 0.91 – 0.99 | 0.81 – 0.84 | Intermediate distribution |
| High Risk | 1.00 or higher | 0.85 or higher | Android (Apple) shape, high visceral fat |
Frequently Asked Questions about Waist to Hip Ratio Calculator
Why is WHR often considered better than BMI?
BMI cannot distinguish between muscle and fat. WHR directly measures abdominal visceral fat, which is the primary driver of cardiovascular disease and type 2 diabetes.
What is an 'apple' vs 'pear' shape?
An apple shape carries fat around the abdomen (visceral fat, higher metabolic risk). A pear shape carries fat on hips and thighs (subcutaneous fat, lower risk).
Where exactly should you measure your waist?
According to the WHO, measure midway between the bottom of your lowest rib and the top of your hip bone (iliac crest), breathing out gently.
How can you reduce your waist-to-hip ratio?
A caloric deficit combined with resistance training and reduction of refined carbohydrates and alcohol reduces visceral abdominal fat stores.
