About ideal weight
There is no single perfect formula for ideal weight. Different medical formulas give slightly different results based on different assumptions about body composition. This calculator shows results from three of the most widely used formulas — Lorentz, Devine and Hamwi — to give you a range rather than a single number.
The healthy BMI range (18.5–24.9) is also shown as a reference. Remember that ideal weight is just a guideline — muscle mass, bone structure and other individual factors all play a role in what is truly healthy for you.
