What this calculator tells you
No equation can identify one perfect body weight. This tool shows the historical Devine estimate beside a broad BMI reference range so the output is treated as context rather than a target.
How to use the Ideal Weight Calculator
- 1
Choose the equation constant and enter height.
- 2
Review both the historical point estimate and broad reference range.
- 3
Do not treat either result as a required goal.
Formula and interpretation
Method
Devine estimate at 5 feet: 50 kg for the male equation or 45.5 kg for the female equation, plus 2.3 kg per inch above 5 feet.
How to read the result
A comfortable, sustainable weight depends on body composition, health, performance, and personal circumstances—not height alone.
Important limitations
The Devine formula began as a medication-dosing estimate and was not designed to define appearance, worth, or an individualized healthy weight.
Ideal Weight Calculator questions
Is there one medically ideal weight?
No. Health and performance can occur across a range, and height-only formulas omit body composition and individual history.
Why show the Devine formula at all?
It remains widely searched and used in some clinical contexts, so showing it with its origin and limitations is more useful than presenting it without context.
