Frequently asked questions

None is authoritative — they were built for drug dosing, not aesthetics. The BMI range is the more clinically useful guide.
Do these account for frame size?
No. Large-framed or muscular people will sit above these numbers at a perfectly healthy body composition.
What do I need to enter into the Ideal Weight Calculator?
Just 2 values: height, sex. Every field starts with a realistic example, so you can change one number at a time and watch the result update instantly.
