About This Tool

The Waist-to-Hip Ratio (WHR) Calculator helps you assess your body fat distribution and associated health risks. WHR is one of the most widely used anthropometric measurements in clinical practice and epidemiological research.

This calculator uses the World Health Organization (WHO) classification system to categorize your result. Unlike BMI, which only considers total body weight relative to height, WHR specifically evaluates where your body stores fat — a critical factor in predicting cardiovascular and metabolic health risks.

For a comprehensive body assessment, combine this tool with our Body Fat Percentage Calculator and Ideal Body Weight Calculator. You can also track your cardiovascular health with our Resting Heart Rate Fitness Score tool.

All calculations happen entirely in your browser — no data is sent to any server. Your measurement history is stored locally and can be cleared at any time.

Frequently Asked Questions (FAQ)

What is the waist-to-hip ratio (WHR)?
The waist-to-hip ratio (WHR) is a simple measurement that compares the circumference of your waist to that of your hips. It's calculated by dividing your waist measurement by your hip measurement. The WHO and medical professionals use WHR as an indicator of health risk related to body fat distribution. You can also use our Body Fat Percentage Calculator for a more detailed body composition analysis.
How do I measure my waist and hips correctly?
Waist: Measure around the narrowest part of your torso, typically at the level of your navel or just above it. Keep the tape horizontal and snug but not compressing the skin.

Hips: Measure around the widest part of your buttocks / hip bones. Stand with feet together and keep the tape level all around.
What is a healthy waist-to-hip ratio?
According to the World Health Organization (WHO), a WHR above 0.90 for men or above 0.85 for women indicates abdominal obesity and increased health risk. A ratio below 0.85 for men or below 0.75 for women is generally considered low risk. However, WHR should be used alongside other metrics like ideal body weight and body fat percentage for a complete picture.
Why is the waist-to-hip ratio important?
WHR is important because it indicates where your body stores fat. People who carry more weight around their waist (apple-shaped) are at higher risk for heart disease, type 2 diabetes, stroke, and certain cancers compared to those who carry weight around their hips (pear-shaped). It provides health risk information that BMI alone cannot.
Is my data secure?
Yes! All calculations happen entirely in your browser. No measurement data is sent to any server. Your calculation history is stored only in your browser's local storage and can be cleared at any time.
How does WHR compare to BMI?
While BMI measures overall body weight relative to height, WHR specifically assesses fat distribution. Someone with a normal BMI can still have a high WHR (indicating central obesity), which carries health risks. WHR is especially useful for people who are muscular or older, where BMI may be less accurate. For related assessments, try our Fitness Age Calculator.
