How to use Ideal Weight Calculator
- Choose your sex.
- Enter your height.
- Compare the four formula results and the healthy BMI range.
About this tool
The Devine, Robinson, Miller and Hamwi formulas were created for clinical dosing and give slightly different answers, so the tool shows all four. They use height and sex only, ignoring frame size and muscle mass, and are best treated as a rough reference.
The healthy BMI range (18.5 to 24.9) is shown as a broader and more current guide. This calculator gives general estimates from standard formulas and is not medical advice. Talk to a doctor or dietitian about your own health.
Frequently Asked Questions
- Which formula is best?
- None is universally best. Using the range between them and the healthy BMI band is more informative than a single number.
- Does it work for children?
- No. The formulas are designed for adults.
