A range, not a target
The four formulas usually disagree by several kilograms, which is the point — treat the spread as a healthy range rather than a single number to chase.
Frequently asked questions
How is ideal weight calculated?
Classic formulas base ideal weight on a baseline at five feet of height, adding a set amount per inch above that. Different formulas use slightly different constants.
Is there one true ideal weight?
No. These formulas give a reference range and ignore build and muscle. A healthy weight is best judged with body composition and how you feel and perform.
