Ideal Weight Calculator FAQs

Is this the weight I should aim for?
Not necessarily — it is a reference point used in some medical contexts (like drug dosing), not a personalized health target. Talk to a healthcare provider for individual guidance.
Which formulas are used to estimate ideal weight?
Several exist, such as Devine, Robinson and Miller, and they give slightly different results depending on height and sex.
Does ideal weight depend on body frame?
Yes. People with larger or smaller frames, and with more muscle, may be healthy at different weights.
Is ideal weight the same as healthy BMI?
They overlap but are not identical. Many people look at a healthy BMI range rather than a single number.
