Find your waist-to-height ratio (WHtR) by dividing waist by height in centimeters. A ratio below 0.5 is generally considered healthy for most adults, while higher values point to more central fat. Use it as a quick screening estimate of cardiometabolic risk.
Enter your waist and height in cm to see your ratio.

How it works
What is the waist-to-height ratio?
The waist-to-height ratio (WHtR) is your waist circumference divided by your height, using the same unit for both. It is a simple way to gauge how much fat sits around your middle relative to your overall size.
Because it accounts for height, WHtR is often considered a better screening tool than waist measurement alone for estimating central fat.
How to read your result
For most adults, a ratio below 0.5 is generally considered healthy, meaning your waist is less than half your height. Higher ratios suggest more central fat and higher cardiometabolic risk.
This is a general screening estimate, not medical advice. Talk to a healthcare professional about your individual situation.
Frequently asked questions
›What is a healthy waist-to-height ratio?
For most adults a ratio below 0.5 is generally considered healthy. Values of 0.5 or above suggest more central fat and warrant a closer look.
›How do I measure my waist correctly?
Wrap the tape around your waist at navel level, breathe out normally, and keep the tape snug and parallel to the floor.
›Do I need to use centimeters?
You can use any unit as long as waist and height use the same one. This calculator expects both values in centimeters.
›Is WHtR better than BMI?
WHtR focuses on central fat, which is closely linked to cardiometabolic risk, so many experts find it a useful complement to BMI.
›Is this calculator medical advice?
No. It is a general screening estimate only. Consult a healthcare professional for diagnosis or personalized guidance.
