How waist to hip ratio works

Waist to hip ratio, often shortened to WHR, is calculated by dividing waist circumference by hip circumference. It is used as a simple anthropometric measure of body shape distribution. A higher waist relative to hip size produces a higher ratio.

Unlike BMI, waist to hip ratio does not use body weight. It focuses specifically on how waist size compares with hip size.

Core formula

How the common thresholds are used

Common WHR interpretation guides often use sex-specific cutoffs. A frequently used reference point is around 0.85 for female values and around 0.90 for male values. This calculator uses those as simple comparison levels to show how current waist size compares with a reference waist for the same hip size.

These thresholds are screening guides only. They are useful for comparison but do not replace a full health assessment.

General WHR guide

Why WHR is useful alongside other measures

Body weight alone does not show how body dimensions are distributed. Waist to hip ratio adds information about waist size relative to hip size. That is why it is often viewed alongside waist-to-height ratio, BMI, and body fat estimates.

This makes WHR a practical body-shape screening tool, especially when you want a quick ratio that does not depend on body weight.
