Good to know
Like BMI, these formulas were derived from population averages and don't account for individual factors like frame size, muscle mass, or body composition — they're a reasonable starting reference point, not a personalized medical target. For a goal that accounts for your actual body composition and health history, a doctor or registered dietitian is a better source than any formula-based calculator.
The formulas behind ideal weight calculators were mostly developed decades ago for specific clinical contexts, like estimating medication dosages by body weight, rather than as general wellness targets — which is part of why different formulas can give noticeably different results for the same height. Treating the output as a broad reference range rather than a precise target reflects how these formulas were actually designed to be used.
Frequently asked questions
It uses the Devine formula, a widely referenced medical estimate based on height — it provides a general reference range, not a precise individual target, since body composition varies.
