Is waist-to-hip ratio better than BMI?
It adds information. BMI does not show where fat sits, while the ratio does. Many researchers consider waist measures alongside BMI to be a better predictor of cardiovascular risk for some people.

About the Waist-to-Hip Ratio Calculator
The waist-to-hip ratio compares how much your weight is carried around the abdomen with how much is carried around the hips. A higher ratio means more fat is stored centrally, which research links to higher risk of heart disease, type 2 diabetes and other metabolic conditions.
Measure the narrowest part of the waist and the widest part of the hips, in the same units. The ratio is the waist divided by the hip. The WHO thresholds are 0.90 for men and 0.85 for women, and the calculator shows which side of the threshold your result falls.
FAQ
Waist-to-Hip Ratio Calculator — frequently asked
Where do I measure the waist?
Measure at the narrowest point between the lower ribs and the hip bones, usually a little above the navel, with the tape level and relaxed breathing. Use the same spot each time.
Where do I measure the hips?
Measure around the widest part of the buttocks, keeping the tape level all the way round. Stand with feet together and weight evenly distributed.
What does a higher ratio mean?
A ratio above the WHO threshold indicates abdominal obesity, meaning fat stored around the organs. It is a risk marker, not a diagnosis. A doctor can check blood pressure, blood sugar and cholesterol for a fuller picture.
Can I change my ratio?
Yes. Regular physical activity, strength training and a diet that keeps calorie intake in balance tend to reduce abdominal fat. Changes often show in waist size before the scale moves a lot.
Is my data stored?
No. The measurements are used only in your browser and nothing is saved.
