Educational estimate for adults, not medical advice, a diagnosis, or a treatment target. Review the method and limitations and discuss individual health questions with a qualified clinician.
Your result
How this calculation works
Men: 50 kg + 2.3 kg per inch above 60 inches. Women: 45.5 kg + 2.3 kg per inch above 60 inches.
View the historical Devine reference-weight estimate for adults at least five feet tall. Despite the common name “ideal weight,” this is not a personal target or a definition of health.
How to use this calculator

Frequently asked questions
Should I aim for this exact weight?
No. This historical equation does not determine an appropriate personal weight or treatment target.
Why is there a minimum height?
This implementation does not extrapolate the above-five-feet equation to shorter heights.
