What Does 'Ideal Weight' Really Mean?
Ideal weight formulas were originally developed for medication dosing, not body image. They estimate the average weight of a healthy person of your height and sex.
Your personal healthy weight depends on body composition, muscle mass, and overall health markers not just a number.

Frequently Asked Questions

All four are validated. Devine and Robinson are most commonly used in clinical settings.
What if I'm muscular?
Ideal weight formulas don't account for muscle. Lifters and athletes can be heavier than the formula suggests and still be healthy.
