Ideal Body Weight & WHO Weight ranges
Ideal Body Weight (IBW) provides a base baseline reference developed for clinical research. The Devine, Robinson, Miller, and Hamwi equations scale weight based on height inches above a 5-foot base.
Body frame sizes adjust formula outcomes by +/- 10%. World Health Organization (WHO) benchmarks set healthy weights within a BMI scale of 18.5 to 25.0. Dosing parameters adjust weight when actual metrics exceed 120% of IBW.
