Which ideal weight formula is most widely used in medicine?
The Devine formula (1974) remains the clinical gold standard for medication dosing and ventilator settings.
Ideal Weight Calculator
Calculates reference ideal body weights using the four major clinical formulas alongside standard WHO BMI healthy weight bounds (18.5 to 24.9).
Scientific Formula & Exercise Physiology Standards
Equation: Devine, Robinson, Miller, & Hamwi Equations | Peer-Reviewed Source: Drug Intelligence & Clinical Pharmacy / American Journal of Hospital Pharmacy
Devine Male: 50 kg + 2.3 kg/in > 5ft | Devine Female: 45.5 kg + 2.3 kg/in > 5ft
Computes target weight benchmarks based on inches above 5 feet (60 inches), providing a comprehensive multi-formula average.
Step-by-Step Worked Example: Devine Formula (5ft 10in Male)
- Inches over 5 feet: 70 - 60 = 10 inches
- Add increment: 50.0 + (2.3 × 10) = 73.0 kg
Calculation Result: Ideal Weight = 73.0 kg (160.9 lbs)
Clinical Nuances, Limitations & Best Practices
- Formulas do not account for muscle mass, bone frame size (small/medium/large), or ethnicity.
