In plain English — what does this do?
🏋️ Your body needs food to move, breathe, and grow — just like a car needs petrol. This tool helps you find out how much food your body needs in a day to feel good and stay healthy!
The waist-to-hip ratio (WHR) is a measurement that compares the circumference of your waist to that of your hips. It is used by the World Health Organization as an indicator of cardiovascular disease risk and abdominal obesity. Unlike BMI, WHR reflects fat distribution rather than total body mass.

What is Waist to Hip Ratio Calculator — Health Risk Indicator?
The waist-to-hip ratio (WHR) is a measurement that compares the circumference of your waist to that of your hips. It is used by the World Health Organization as an indicator of cardiovascular disease risk and abdominal obesity. Unlike BMI, WHR reflects fat distribution rather than total body mass.
How to use it
- 1️⃣ Select your biological sex, as risk thresholds differ between males and females.
- 2️⃣ Choose your preferred unit of measurement — centimetres or inches.
- 3️⃣ Measure your waist at its narrowest point, typically just above the belly button.
- 4️⃣ Measure your hips at their widest point, around the buttocks.
- 5️⃣ Enter both values and read your ratio along with the WHO risk classification.

❓ Common questions
- What is a healthy WHR for men?
- For men, a WHR of 0.95 or below is considered low risk. Between 0.96 and 1.0 is moderate risk, and above 1.0 is high risk according to WHO guidelines.
- What is a healthy WHR for women?
- For women, a WHR of 0.80 or below is low risk. Between 0.81 and 0.85 is moderate risk, and above 0.85 is considered high risk by WHO standards.
- Is WHR better than BMI?
- WHR can be a better predictor of cardiovascular risk because it measures fat distribution. Central (abdominal) fat is more metabolically active and carries higher health risks than fat stored elsewhere.
- Where exactly should I measure my waist?
- Measure your waist at its natural narrowest point, which is usually about an inch above your belly button. Stand relaxed, exhale normally, then take the measurement.
- Can WHR change with exercise?
- Yes. Cardiovascular exercise and strength training can reduce waist circumference over time by decreasing visceral fat. This improves your WHR even if your overall weight does not change significantly.
