Waist-to-Hip Ratio (WHR)
Waist divided by hip circumference — a classic central-obesity index that predates WHtR. The military uses WHtR now, but WHR remains useful in health screening.
Formula
WHR = waist (in) ÷ hip (in)
Healthy range
Men: < 0.90 healthy, ≥ 0.95 high risk · Women: < 0.85 healthy, ≥ 0.90 high risk.
Military & first-responder angle
Not used in current military standards (WHtR replaced it as the screen of choice in 2026), but still relevant when comparing older research and health-risk literature.
Calculator
The 2026 Department of Defense primary screen: waist ÷ height. Under 0.55 clears the joint-force screen; the Marine Corps sets a tighter 0.52.
