About IBW Calculator

Ideal Body Weight (IBW) is a clinical guideline for the weight considered healthy for a given height and gender. It is frequently used in medicine to calculate drug dosages, nutritional requirements, and fitness goals.

Formula
Male:   50 + 2.3 × (height_in − 60)
Female: 45.5 + 2.3 × (height_in − 60)
(Devine Formula)
The result shows your IBW ± 10% as a healthy range. A 5-foot person is the baseline (60 inches).
