Formula and Assumptions
Devine, Robinson, Miller, and Hamwi formulas estimate ideal body weight from height and sex.

Different formulas were designed for different clinical contexts, so the average is a reference point only.

Athletes, older adults, and pregnant people may not fit these ranges well.

Reference Upgrade
Built from the Calculator.net model, with added context.

Live validation and instant result updates instead of a submit-only workflow.

Multiple decision metrics are shown together, not only the primary answer.

Formula notes and assumptions are visible on the page so the math is easier to audit.

Reference Model

Modeled after the input style and primary output on Calculator.net's Ideal Weight Calculator.

The page keeps the math in one place and exposes the assumptions beside the result.

Default inputs: sex=male, heightFeet=5, heightInches=10
