Ideal Weight Calculator — Ideal body weight (IBW) is a clinical estimate based on height and sex. Four formulas are commonly used: Devine (1974, the standard for drug dosing), Robinson (1983), Miller (1983), and Hamwi (1964). This tool shows all four plus the simple mean, and a BMI-based healthy range for comparison.

What is ideal weight calculator?
Ideal body weight (IBW) is a clinical estimate based on height and sex. Four formulas are commonly used: Devine (1974, the standard for drug dosing), Robinson (1983), Miller (1983), and Hamwi (1964). This tool shows all four plus the simple mean, and a BMI-based healthy range for comparison.
Ideal body weight formulas are most useful as a reference point. They were derived from actuarial tables of height and weight in healthy adults and are not a target for everyone. Use them alongside body composition, lifestyle, and your own health data.
