What is Ideal Body Weight?

Ideal Body Weight (IBW) is an estimate of a healthy weight based on height and gender. It is commonly used in medicine and fitness to guide weight management and assess health risks. The Devine formula is a widely used method for calculating IBW.

Devine Formula (1974)

  • For men: IBW = 50 + 2.3 × (height (in) – 60)
  • For women: IBW = 45.5 + 2.3 × (height (in) – 60)
  • Height is in inches. 1 inch = 2.54 cm.

Example Calculation

Suppose a woman is 165 cm tall:

Height (in) = 165 / 2.54 = 64.96 IBW = 45.5 + 2.3 × (64.96 – 60) = 45.5 + 2.3 × 4.96 = 45.5 + 11.41 = 56.91 kg
