About Ideal weight calculator
Ideal body weight formulas such as Devine and Hamwi estimate a reference weight from height and sex for adult populations.
They are historical screening tools, not personalized targets. Muscle mass, age, and health conditions change what is healthy for an individual.
Use results as a conversation starter with a clinician, not as a diet prescription.
How to use it
- 1Enter height and select sex for the formula variant.
- 2Read the estimated ideal weight range.
- 3Discuss with a qualified professional before changing diet or training.
Frequently asked questions
- Is one formula better?
- Different formulas give slightly different numbers; think of ideal weight as a band, not a single target.
- Children?
- Adult formulas do not apply to pediatric growth curves.
