Waist-to-height ratio (WHtR) is a simple screening tool. Values under 0.5 are generally considered lower risk for many adults.
How it works
- Measure your waist at the navel.
- Enter your height.
- See your ratio and a general risk category.
Frequently asked questions
What is a healthy ratio?
Under 0.5 is often cited as lower risk. This is a population screen, not a diagnosis.
How do I measure waist?
At the midpoint between the bottom of the ribs and the top of the hips, or at the navel.
Is this better than BMI?
It focuses on abdominal fat, which is more strongly linked to metabolic risk than BMI alone for some people.
