📘 About the Waist-Hip Ratio

The waist-to-hip ratio (WHR) compares the size of your waist to your hips. It shows where you carry fat: fat around the waist is linked to a higher risk of heart disease and type 2 diabetes.

Measure your waist at its narrowest point or at the navel, and your hips at the widest point, then enter both in centimetres.

🧮 Formula

Waist-to-hip ratio
WHR = Waist circumference ÷ Hip circumference

Where

❓ Frequently asked questions

How do I measure correctly?

Stand upright, breathe out normally and measure over light clothing. Keep the tape level and snug but not tight.

Is WHR better than BMI?

It captures fat distribution, which BMI cannot. Doctors often use both.

What if the ratio is high?

Talk to a doctor. Regular activity, a balanced diet and better sleep help reduce belly fat.
