What This Calculator Does
The Ideal Weight Calculator estimates a healthy target weight for your height using the widely referenced Devine formula. It is a practical reference for setting goals, not a medical prescription.
How It Works
The Devine formula anchors on 50 kg (men) or 45.5 kg (women) at 60 inches and adds 2.3 kg for every inch beyond. The tool converts your height to inches, applies the formula, and also reports the figure in pounds.
Example
A man 175 cm (about 69 inches) tall has an ideal weight near 50 + 2.3 x 9 = 70.7 kg, or about 156 lbs.
Formula
IBW = 50 + 2.3 × (height_in − 60)Devine formula; women use 45.5 as the base.

A height-based reference weight from the Devine formula, useful as a target anchor rather than a strict goal.
Frequently Asked Questions
How is ideal weight determined?
Formulas like Devine correlate height with weight associated with lower mortality risk. They provide a reference range rather than an exact target.
Is ideal weight the same for athletes?
No. Muscular individuals may sit above formula estimates while remaining healthy, which is why body-fat percentage adds useful context.
Should I aim exactly for this number?
Use it as a guide within the healthy BMI range for your height. Individual builds vary.
