About Ideal Weight Formulas

Several formulas have been developed over the decades to estimate ideal body weight. None is perfect — they are all approximations based on population averages:

  • Devine (1974): Developed for drug dosing. IW (men) = 50 + 2.3×(height_in − 60)
  • Robinson (1983): Revision of Devine. IW (men) = 52 + 1.9×(height_in − 60)
  • Miller (1983): Another revision. IW (men) = 56.2 + 1.41×(height_in − 60)
  • Hamwi (1964): Older clinical formula. IW (men) = 48 + 2.7×(height_in − 60)

Treat the results as a healthy reference range, not a strict target. Body composition, muscle mass, and frame size matter as much as the number on the scale.
