The Waist to Height Ratio Calculator is a simple tool that tells you if your waist size is healthy for your height. It’s more useful than BMI when it comes to checking fat around your belly, which is linked to health problems like heart disease and diabetes.
What is Waist to Height Ratio?
This ratio compares your waist size to your height. It gives you an idea of how much fat you carry around your middle. The formula is easy:
Waist to Height Ratio (WHtR) = Waist circumference ÷ Height
Both values should be in the same unit — either inches or centimeters.
Why It Matters
Fat around the waist is more dangerous than fat in other parts of the body. It increases the risk of high blood pressure, type 2 diabetes, and heart issues. WHtR helps you track this better than BMI because BMI doesn’t tell you where fat is located.
Healthy WHtR Ranges
Here’s what your ratio result may mean:
Under 0.40: Underweight
0.40 - 0.49: Healthy range
0.50 - 0.59: Overweight, increased health risk
0.60 or more: High risk of obesity-related problems
Example
If someone’s waist is 80 cm and their height is 170 cm, then:
WHtR = 80 ÷ 170 = 0.47
This means they are in the healthy range, which is great for long-term health.
How to Measure Correctly
Use a measuring tape to measure your waist at the narrowest point, usually just above your belly button. Stand straight and relaxed. For height, stand without shoes and keep your back straight for an accurate measurement.
