What is Ideal Body Weight (IBW)?

Ideal Body Weight (IBW) is an estimate of a healthy weight based on height, gender, and age. It serves as a reference to assess whether an individual’s weight is in a healthy range and assists in medical dosages and nutritional planning.

How is Ideal Body Weight Calculated?

IBW is calculated using various formulas. Some commonly used methods include:

Devine Formula

Men: IBW (kg) = 50 + 2.3 × (height in inches - 60)
Women: IBW (kg) = 45.5 + 2.3 × (height in inches - 60)

Robinson Formula

Men: IBW (kg) = 52 + 1.9 × (height in inches - 60)
Women: IBW (kg) = 49 + 1.7 × (height in inches - 60)

Miller Formula

Men: IBW (kg) = 56.2 + 1.41 × (height in inches - 60)
Women: IBW (kg) = 53.1 + 1.36 × (height in inches - 60)

Hamwi Formula

Men: IBW (kg) = 48 + 2.7 × (height in inches - 60)
Women: IBW (kg) = 45.5 + 2.2 × (height in inches - 60)

Example Calculation

Let’s calculate IBW using the Devine Formula for a male with a height of 5 feet 10 inches (70 inches):

IBW = 50 + 2.3 × (70 - 60)
IBW = 50 + 2.3 × 10 = 73 kg
