Waist-to-Height Calculator
Waist-to-height ratio is a simple, strong indicator of metabolic risk. A good rule of thumb: keep your waist under half your height.
Measure your waist at the navel. Enter waist and height to see your ratio.
This ratio is a general screening indicator, not a diagnosis. Many factors affect health. Always consult a licensed physician for medical advice.
Good to know
What is a healthy ratio?
Keeping your waist under half your height (a ratio below 0.5) is linked to lower metabolic risk.
Why use this instead of BMI?
It reflects belly (visceral) fat, which drives metabolic risk, better than BMI does for many people.
Where do I measure my waist?
At the level of your navel, standing relaxed, without pulling the tape tight.
