Ideal Weight Calculator
Compare four classic ideal-body-weight reference equations: Devine, Robinson, Miller, and Hamwi.
How to use
- Choose reference sex and enter height from 120 to 230 cm.
- Compare the four kilogram estimates, average, minimum, and maximum.
Capabilities and scope
Rather than presenting one correct target, the runner shows each estimate plus their average and range.
How it works
Height is converted to inches and each sex-specific equation applies its coefficient above five feet.
Example
A 175 cm male reference produces four different classic-equation estimates and a summary range.
Interpretation
The displayed average is only a convenience summary, not a separate validated equation.
Useful for
- Compare how classic IBW equations differ at one height
- Check equations cited in older clinical or research contexts
Before you use it
- These estimates are not direct body-composition measurements or individualized health targets.
Edge cases
- Heights outside 120–230 cm are rejected.

Frequently asked questions
Why do the formulas disagree?
They were developed with different coefficients and source populations, so identical height can produce different estimates.
