One body-size number rarely tells the whole story, but it can answer a precise question. Waist to Hip Ratio Calculator is built for that narrower job.

What this calculator does

Waist-to-hip ratio, or WHR, is a compact way to describe how waist size compares with hip size. It is often used as one marker of central fat distribution. Anthropometric equations are convenient because they use simple measurements, but they describe body size or proportion rather than directly measuring tissue composition or health.

How to use it

Enter or select Waist circumference and Hip circumference. Use the units offered by the calculator and keep measurements consistent when you plan to compare results over time.

How the calculation works

The calculation is direct: waist circumference divided by hip circumference. Because it is a ratio, the same length unit can be used for both measurements.

Example

For the sample values prefilled in this calculator, the primary result is 0.85 (Waist-to-hip ratio). This example is there to show how the inputs flow through the implemented equation; replace the sample values with your own measurements before using the result.

How to interpret the result

A larger ratio means the waist is larger relative to the hips. The number can be followed over time, but health-risk cutoffs depend on sex, population, measurement protocol, and the guideline being used.

Limitations and notes

WHR does not measure total body fat or diagnose metabolic disease. Tape placement, posture, breathing, and abdominal distension can affect the result, so standardized measurement technique matters. For repeat measurements, consistency usually matters more than false precision: use the same unit system, the same tape or scale when possible, and the same anatomical landmarks. A small change near a category boundary should be viewed in context rather than treated as a sudden biological change.
