About Ideal Weight Formulas

These formulas were developed based on population studies and provide estimates of ideal body weight based on height and gender. Each formula has its own methodology:

  • Robinson Formula: Considered the most accurate for most people
  • Miller Formula: Tends to give higher estimates
  • Devine Formula: Originally created for medication dosing
  • Hamwi Formula: One of the earliest formulas developed

Note: These are estimates only. Ideal weight varies based on body composition, muscle mass, and individual factors. Consult a healthcare provider for personalised advice.
