The Devine Formula
Developed by Dr. BJ Devine in 1974, this formula was originally created to calculate drug dosages based on ideal body weight. It has since become one of the most widely used formulas in clinical practice for estimating healthy weight.
The Formula
For men: IBW = 50 kg + 2.3 kg per inch over 5 feet
For women: IBW = 45.5 kg + 2.3 kg per inch over 5 feet
This formula is simple, clinically validated, and works well for most adults of average height.
Clinical Use
The Devine formula is used to calculate medication doses, determine nutritional requirements, estimate creatinine clearance, and set weight loss goals. It's particularly important for drugs with narrow therapeutic windows.
