What This Calculator Does
The Waist-to-Height Ratio Calculator compares your waist circumference to your height. Research consistently shows that a ratio above 0.5 signals increased risk of diabetes, heart disease, and early mortality.
How It Works
Divide waist circumference in centimeters by height in centimeters. A result below 0.5 is healthy. Between 0.5 and 0.6 indicates elevated risk. Above 0.6 indicates high risk.
Example
Someone with an 82 cm waist and 175 cm height has a WHtR of 0.47, safely below the 0.5 threshold.
Formula
WHtR = Waist / HeightReading the Results
Waist-to-Height Ratio
Below 0.5 = healthy. 0.5 to 0.6 = elevated risk. Above 0.6 = high risk of cardiometabolic disease.
Frequently Asked Questions
Why is waist-to-height better than BMI?
WHtR accounts for where you carry fat, not just total weight. It consistently outperforms BMI at predicting cardiovascular and metabolic risk.
What does a WHtR of 0.5 mean?
At 0.5 you are at the boundary. The recommendation is to stay below this threshold to minimize long-term health risks.
Does this work for children?
WHtR is validated for adults. For children, age-specific growth charts are more appropriate.
