Ideal Weight Calculator

How ideal weight is calculated

Ideal body weight (IBW) formulas estimate a target weight range based on height and biological sex. This tool uses four widely-cited formulas: Devine (1974, the most common clinical reference), Robinson (1983), Miller (1983), and Hamwi (1964). All are based on height above 5 feet. The average of the four gives a balanced estimate. Note that IBW is a clinical reference tool and does not account for muscle mass, bone density, or body composition — consult a healthcare provider for personalized advice.
