Why 'Ideal Weight' Formulas Don't Tell the Whole Story

Classic ideal weight formulas like Hamwi and Devine were developed decades ago, primarily for medical dosing calculations — not as fitness or aesthetic targets. They produce a single number based purely on height, completely ignoring muscle mass, frame size, and body composition.

Two people at the same height can have very different healthy weights depending on muscle mass and frame. An athletic person with significant muscle will weigh more than these formulas suggest while still being lean and healthy — the formulas simply weren't designed with muscular builds in mind.

A healthy weight range based on BMI (18.5-24.9) is generally a more useful guide than a single "ideal" number, since it acknowledges that a range of weights can be healthy for any given height rather than pretending there's one correct number.

Use the calculator above for a rough reference point across multiple formulas, but combine it with how you actually feel, your energy levels, and ideally body composition measurements — a number on a formula shouldn't override how your body is actually functioning.
