Ideal Weight Calculator
Compare Devine, Robinson, Miller and Hamwi-style ideal-weight estimates with the mathematical adult BMI 18.5–24.9 weight range.
Compare several traditional ideal-body-weight formulas and the mathematical healthy BMI range without treating a single number as a universal target.
Why there is no single ideal weight
Healthy body weight depends on height, body composition, age, sex, health status and individual circumstances. Formula-based estimates are only reference points.
Formula comparison
The calculator compares Robinson, Miller, Devine and Hamwi-style equations so users can see how different historical formulas produce different estimates.
Healthy BMI range
For adults, the calculator also shows the weight interval corresponding to the standard BMI reference range. This is a mathematical range, not a personalized medical target.
How to use the result
Use the group of estimates as context and focus on sustainable health measures rather than chasing the lowest or highest number.
Limitations
The formulas were designed for population-level estimation and may be less meaningful for athletes, older adults, children or people with unusual body composition.
Health note
Discuss weight goals with a qualified healthcare professional when health conditions, pregnancy or eating concerns are involved.

Questions & Answers
Frequently Asked Questions
What does the Ideal Weight Calculator calculate?
It provides an estimate from the inputs you enter. Review the detailed guide on this page for formulas, interpretation, assumptions and limitations.
Is there one ideal weight for everyone?
No. Traditional formulas produce different reference estimates, and the mathematical BMI weight range is also only a reference. Healthy weight depends on more than one number.
What formulas does the Ideal Weight Calculator compare?
The tool compares Devine, Robinson, Miller and Hamwi-style traditional formulas and also calculates the adult BMI 18.5–24.9 weight range.
Is the BMI weight range a personal target?
No. It is a mathematical reference range based on adult BMI cutoffs, not a personalized medical target.
