Waist-to-height ratio
Enter your waist and height (same unit): calculate the ratio and find out which range you're in.
What it's for
The waist-to-height ratio is an indicator of belly fat often more reliable than BMI alone. The simple rule: your waist should be less than half your height (ratio < 0.5).
How to measure
Measure the waist at navel level, relaxed, and height in the same unit. Not a diagnosis: for health assessments see your doctor.
