⚖️ How to Calculate Ideal Body Weight: Complete Guide
Ideal Body Weight (IBW) provides a target range for optimal health based on your height, gender, and body frame. While not a perfect measure for everyone, understanding IBW helps set realistic health and fitness goals.
📚 IBW Calculation Formulas
Devine Formula (Most Common)
Men: \textIBW = 50 + 2.3 × (\textheight in inches - 60)
Women: \textIBW = 45.5 + 2.3 × (\textheight in inches - 60)
Hamwi Formula
Men: \textIBW = 48 + 2.7 × (\textheight in inches - 60)
Women: \textIBW = 45.5 + 2.2 × (\textheight in inches - 60)
🎨 Example Calculation
Example: 5'6" (66 inches) female
Using Devine Formula:
- Base weight: 45.5 kg (100 lbs)
- Height over 5 feet: 66 - 60 = 6 inches
- Additional weight: 2.3 × 6 = 13.8 kg
- IBW: 45.5 + 13.8 = 59.3 kg (131 lbs)
Healthy Range: ±10% = 119-143 lbs
🌍 Adjustments & Considerations
Frame Size
- Small frame: -10% from IBW
- Medium frame: IBW as calculated
- Large frame: +10% to IBW
Age Adjustments
- Over 50: May carry extra weight healthily
- Body composition: Muscle weighs more than fat
