DocomintIdeal Weight Calculator
Estimate a healthy target weight from height and gender using the Devine formula.
The Devine formula was originally developed for calculating medication dosages, not as a fitness target — hospitals and clinicians still use it as a quick, height-only reference point, but it doesn't account for frame size, muscle mass, or individual build, so treat the result as a rough baseline, not a personal goal weight.
Example: A man at 175cm (about 68.9 inches) has an estimated ideal weight of about 70.6kg using the Devine formula — a starting reference point, not a target that accounts for someone with an athletic, muscular build.
How it works
- Enter your gender and height

Frequently asked questions
Where does the Devine formula come from?
It was developed in 1974 by Dr. B.J. Devine, originally to help calculate appropriate medication dosages — not as a fitness or aesthetic target — and became a widely adopted clinical reference specifically because of that dosing use case.
Should I use this as a personal fitness goal weight?
Treat it as a rough population-level reference, not a personalized target — it doesn't account for frame size, muscle mass, or individual build, so an athletic person's healthy weight can reasonably sit well above the Devine formula's estimate.
