Ideal Weight Calculator
Your ideal body weight by four standard medical formulas, plus the healthy BMI range.
Where these formulas come from
The Devine formula (1974) was created for drug dosing, not aesthetics, and became the medical default; Robinson and Miller are 1983 refinements of it, and Hamwi (1964) predates them all. Each gives a single reference weight for your height and sex. Expect them to disagree by a few kilos; that spread is the honest answer.
A healthier way to read the numbers
There is no single ideal weight. Frame size, muscle mass and age all shift what's healthy, which is why the healthy BMI range (18.5 to 25) is shown as a range. If you're within it and your waist circumference is reasonable, the formula differences are noise. See also the BMI calculator and body fat calculator.
