Ideal Weight Calculator

Ideal Body Weight (IBW) is an estimate of optimal weight based on height and gender, often used for medication dosing and health risk assessment. One common method is the Devine formula:

Devine Formula:
For men: IBW = 50 kg + 2.3 kg × (height in inches over 5 feet)
For women: IBW = 45.5 kg + 2.3 kg × (height in inches over 5 feet)
  • IBW is only an estimate and does not account for muscle mass or body composition.
  • It is primarily useful for determining drug dosages.
