Estimez un poids cible sain à partir de la taille et du genre avec la formule de Devine.
What is a Calculatrice de Poids Idéal?
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.
How to use the Calculatrice de Poids Idéal
- Enter your gender and height
- Press Calculate
- An estimated ideal weight appears instantly, computed on your device using the Devine formula
Formula
Men: 50 + 2.3 × (height in inches − 60) | Women: 45.5 + 2.3 × (height in inches − 60)
The Devine formula, defined over a 5-foot (60-inch) baseline height — this tool converts your entered centimeters to inches internally before applying it.
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.
Common mistakes
- Treating the result as a personal fitness or aesthetic goal rather than the medical dosing reference it was originally designed as.
- Applying it to someone under 5 feet tall (60 inches), where the formula's baseline assumption and reliability get shakier.
- Expecting it to account for frame size or muscle mass — the formula uses height alone, nothing else.
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.
What about someone shorter than 5 feet (60 inches)?
The formula was defined with 60 inches as its baseline, and results below that height extrapolate the same linear relationship — still computable, but treat the estimate as less reliable the further below 60 inches the height is.
Are there other ideal weight formulas besides Devine?
Yes — Robinson, Miller, and Hamwi are other commonly cited formulas, each with slightly different coefficients and typically producing results within a few kilograms of each other. This tool uses Devine specifically, the version most widely referenced for clinical dosing.
