Your Ideal Weight Range
What Is the Ideal Body Weight (IBW)?
The concept of "Ideal Body Weight" was originally introduced to help medical professionals calculate accurate drug dosages. Over the decades, multiple formulas have been developed. Because everyone's body composition is unique, no single formula is definitively correct — which is why we show results from four of the most cited medical formulas simultaneously.
The Four Formulas Explained
- Devine (1974): Originally created for drug dosing calculations. Still widely used in clinical settings.
- Robinson (1983): A refined version of Devine's formula based on a broader population study.
- BMI Method: Calculates the weight range for a "healthy" BMI (18.5–24.9) at your specific height.
- Miller (1983): Generally produces lighter results and is considered more suitable for smaller-framed individuals.
Frequently Asked Questions
Is there one "perfect" ideal weight?
No. Ideal weight is a range, not a single number. Factors such as muscle mass, bone density, age, genetics, and ethnicity all influence what a truly healthy weight looks like for any specific individual.
