The Devine formula (1974), widely used in clinical pharmacology to dose medications. It gives a single target weight based on height and sex rather than a range.

No — the Devine formula was derived independently and gives a slightly lower target for many people, particularly those under 5'5". The midpoint of a healthy BMI range often differs by a few kilograms.

Ideal weight formulas are population averages and do not account for frame size or muscle mass. Use it as a general guideline, not a strict target. Body fat percentage is often a more meaningful measure.

The healthy weight range (BMI 18.5–24.9) spans several kilograms, while the Devine formula gives a single point estimate. Both are useful reference points; the range gives you more realistic flexibility.
