Direct answer

Waist-to-Hip Ratio (WHR) Calculator gives an instant result from your inputs. Waist-to-hip ratio (WHR) is a simple measure of body fat distribution. It compares your waist circumference to your hip circumference. Formula snapshot: WHR is computed as waist / hip. Example: Waist: 80cm, Hip: 100cm -> WHR = 0.80.

About this calculator

Waist-to-hip ratio (WHR) is a simple measure of body fat distribution. It compares your waist circumference to your hip circumference.

Many health guidelines use WHR as a screening metric for central fat distribution. It is not a diagnosis, but it can be useful for tracking changes over time.

For a related metric that uses height instead of hip circumference, see the Waist-to-Height Ratio calculator.

How it works

A quick explanation of the logic behind the results, so you can trust what you see.

WHR is computed as waist / hip.
Because it is a ratio, units cancel out (cm/inches both work as long as both are the same).
The tool also shows a basic category using common thresholds for men and women.
WHR is best used for trend tracking rather than a single measurement.

Formula used

These are the core formulas and logic rules used by this calculator.

WHR is computed as waist / hip.
Because it is a ratio, units cancel out (cm/inches both work as long as both are the same).

Common use cases

Below are common real-world scenarios where this calculator is useful.

Tracking waist vs hip change over time
General screening for central fat distribution
Fitness progress check-ins
Comparing body shape changes during recomposition
Simple metric to pair with BMI
Coaching and habit tracking
Goal setting for waist reduction
Lifestyle progress tracking (non-diagnostic)

How to use

Select sex for reference thresholds.
Measure waist circumference (tape level, relaxed).
Measure hip circumference (widest point).
Calculate to see WHR and a basic risk category.
Re-measure if the ratio looks unexpected.

Common mistakes to avoid

These are the issues that most often cause confusing results.

Measuring waist at different locations each time.
Not measuring at the widest hip point.
Pulling tape too tight or measuring over thick clothing.
Using different units for waist and hip (must match).
Treating the category as a medical diagnosis.

Tips and notes

Measure under similar conditions each time (same time of day).
Use a flexible tape and keep it level around your body.
Track WHR alongside waist-to-height ratio for a broader view.
If you want an estimate of body fat percentage, use the Body Fat Percentage calculator.
Small changes can matter. Watch long-term trends rather than daily variation.

Glossary

Quick definitions for common terms used in this calculator.

WHR

Waist-to-hip ratio: waist circumference divided by hip circumference.

Central fat

Fat carried around the abdomen area (non-diagnostic term).

Examples

Example WHR

Input: Waist: 80cm, Hip: 100cm

Output: WHR = 0.80

Another example

Input: Waist: 92cm, Hip: 98cm

Output: WHR = 0.94

Trend tracking

Input: Waist decreases while hips stable

Output: WHR decreases over time

FAQ

What is a good WHR?

It depends on the reference you use. Many guidelines suggest lower WHR is generally better for central fat distribution. Use this as a screening metric only.

Do units matter?

No, as long as waist and hip are measured in the same unit.

Why do you ask for sex?

Common reference thresholds differ between men and women.

Is WHR better than BMI?

They measure different things. BMI is weight-to-height, WHR is fat distribution. Together they provide better context.

Can I use WHR to diagnose health issues?

No. It is a screening metric. Consult a qualified professional for health decisions.

How often should I measure?

Weekly or monthly is usually enough for trend tracking. Daily changes are often noise.

Is this calculator free to use?

Yes. This calculator is free to use without signup.

Can I use this calculator on mobile?

Yes. The calculator is mobile-friendly and works on desktop as well.
