Calculate your waist-to-height ratio using the "keep your waist below half your height" health guideline.
How It Works
How Waist-to-Height Ratio Calculator Works
Waist circumference divided by height gives a ratio that's been proposed as a simpler, single-number alternative to BMI for flagging health risk, since — like the waist-to-hip ratio — it doesn't require unit conversion as long as both measurements match.
FAQ
Frequently Asked Questions
Why is 0.5 the commonly cited threshold?
Public health messaging has settled on "keep your waist circumference below half your height" as an easy-to-remember rule of thumb, since ratios above that point have been associated with increased risk across a wide range of heights.
Is this considered better than BMI?
Some research suggests it tracks central (abdominal) obesity risk better than BMI, since BMI can't distinguish where on the body weight is carried — but like all single-number health metrics, it's a screening tool rather than a diagnosis.
