Ideal Weight Calculator
Estimate ideal body weight using the Devine formula based on height and gender.
Results
The Devine formula is one of the most widely used clinical formulas for estimating ideal body weight. Originally developed in 1974 for drug dosage calculations, it gives a quick reference point based on height and gender. Keep in mind that ideal weight varies based on frame size, muscle mass and individual health factors - this is a general guideline rather than a strict target.
