What is Ideal Body Weight?
Ideal Body Weight (IBW) is a range suggested by medical research that correlates with the lowest mortality and disease risk for a given height and gender. It was originally developed for medical dosing.
Standard Formulas
Common formulas include Robinson, Miller, and Devine. For example, Miller's: Men = 56.2kg + 1.41kg per inch over 5 feet; Women = 53.1kg + 1.36kg per inch over 5 feet. These are guidelines, not absolute targets.

- Devine (1974): Originally developed for drug dosage calculations, tends to give higher values for taller people.
- Miller (1983): Produces slightly higher baseline weights, flatter increase per inch.
- Hamwi (1964): One of the earliest formulas, commonly used in clinical settings.
