Ideal weight (average)

These formulas are reference points from population studies, not personal targets. Muscle mass, frame size, age, and ethnicity all affect what a healthy weight means for you.

Common Mistakes to Avoid

These formulas don't use age or current weight. All four are height-and-sex only, originally built for drug dosing — they won't adjust for your age, frame size, or muscle mass the way a personalized target would.
A range is more honest than one number. The four formulas can differ by several kilograms for the same height — treat the spread as the real reference point, not just the average.
This isn't a diagnosis of your current weight. Falling outside these formulas' output doesn't mean anything is wrong — they're population-average reference points, not individual health targets.
