Quick answer
Ideal body weight formulas estimate a target from height alone; the healthy BMI range gives a more useful window than any single number.

Frequently asked questions
Which formula is best?
None is authoritative — they were built for drug dosing, not aesthetics. The BMI range is the more clinically useful guide.
Do these account for frame size?
No. Large-framed or muscular people will sit above these numbers at a perfectly healthy body composition.
