FAQ
Common questions
Is there really an ideal weight?
No, there is a healthy weight range. "Ideal" weight formulas were originally created for clinical drug-dosing rather than for setting personal goals. Use the result as a rough target, not a strict number.
Why do four formulas give different answers?
Each was derived in a different decade, from a different population sample, with a different goal. We show all four because seeing the spread reminds you that any single number is an approximation.
I'm muscular — these numbers seem low.
Classic formulas were calibrated on average sedentary populations. If you train regularly, your healthy weight will be higher than these formulas suggest because of greater lean mass.
