Frequently Asked Questions
Which formula is most accurate?
No single formula is universally accurate. These are guidelines. The Devine formula is most widely used in clinical settings (e.g., for drug dosing).
Does body frame size affect ideal weight?
Yes. The Hamwi formula originally included ±10% adjustments for small and large frames. Use the range as a guide, not a precise target.
