Calculate your waist-to-hip ratio, a measure the WHO uses to assess health risk related to fat distribution.
How It Works
How Waist-to-Hip Ratio Calculator Works
Waist circumference divided by hip circumference gives a simple ratio — since both measurements use the same unit, it doesn't matter whether you measure in inches or centimeters, as the units cancel out.
FAQ
Frequently Asked Questions
Why does fat distribution matter, not just total body fat?
Fat carried around the waist ("apple" shaped) is more strongly linked to cardiovascular and metabolic risk than fat carried around the hips ("pear" shaped), which is exactly what this ratio is designed to flag.
Where does the 0.90 / 0.85 threshold come from?
Those are the WHO's commonly cited cutoffs for men and women respectively, above which abdominal obesity risk is considered elevated — individual risk still depends on many other factors beyond this one ratio.
