What is Ideal Body Weight?
Ideal Body Weight (IBW) is the weight at which a person is considered healthiest based on their height and gender. Our calculator uses four scientifically validated formulas (Devine, Robinson, Miller, and Hamwi) to provide a comprehensive view of your ideal weight range. These formulas have been used by healthcare professionals for decades.

Frequently Asked Questions
What formulas does this ideal weight calculator use?
Our calculator uses four established medical formulas: Devine (1974), Robinson (1983), Miller (1983), and Hamwi (1964). Each formula was developed for clinical use and provides slightly different results based on different assumptions about body composition.
Why do the formulas give different results?
Each formula was developed using different population samples and methodologies. The Devine formula is commonly used for drug dosing, while Robinson and Miller were developed to improve accuracy. We recommend using the average as a general guideline.
Is ideal body weight the same as healthy weight?
Ideal body weight formulas provide estimates based primarily on height. A healthy weight range (based on BMI 18.5-24.9) may be more practical. Factors like muscle mass, body composition, and individual health conditions should also be considered.
