Ideal Weight Calculator
The Ideal Weight Calculator estimates a healthy target body weight for your height and gender using the Devine formula, a method originally developed for medical dosing calculations and widely adopted as a general reference.

How ideal weight is estimated
Men: IBW (kg) = 50 + 2.3 × (height in inches − 60)
Women: IBW (kg) = 45.5 + 2.3 × (height in inches − 60)
The formula uses 5 feet (60 inches) as a baseline and adds 2.3 kg for every inch above that.
Example: A man who is 5'9" (69 inches) has an estimated ideal weight of 50 + 2.3 × 9 = 70.7 kg, or about 155.9 lb.
Limitations
This is one of several "ideal weight" formulas (others include Robinson, Miller, and Hamwi), and all of them are rough estimates that don't account for muscle mass, frame size, or individual body composition. Use alongside our BMI Calculator and Body Fat Calculator for a fuller picture, and consult a healthcare provider for personalized guidance.
