Understanding Ideal Weight

Formula Comparison

  • Hamwi: Oldest formula, originally for drug dosing
  • Devine: Most commonly used in medical practice
  • Robinson: Tends to give slightly lower weights
  • Miller: More recent, balanced approach

Example Calculation

Female, 5'6" (167.64 cm)

Hamwi: 45.5 + (2.2 × 6) = 58.7 kg (129.5 lb)

Devine: 45.5 + (2.3 × 6) = 59.3 kg (130.7 lb)

BMI Range: 51.9-70.1 kg (114.5-154.5 lb)

Important Considerations

  • Formulas don't account for body composition
  • Athletes may weigh more due to muscle mass
  • BMI range provides more flexibility
  • Individual health factors are important

When to Use Each Method

  • Formulas: Quick estimates, medical dosing
  • BMI Range: General health guidelines
  • Professional Assessment: Body composition analysis
  • Personal Goals: Consider fitness and health status
