How is the healthy weight range calculated?

It is the range of weights that would give you a BMI between 18.5 and 24.9 at your entered height — the standard "normal weight" BMI category.

Is a healthy weight range the same for men and women?

Yes, because it is based purely on the BMI formula, which does not adjust for sex — only your height changes the result.

What if my weight falls outside this range?

Falling outside the range does not necessarily mean poor health, especially for very muscular people, but it can be a useful signal to discuss with a healthcare provider.

How it works

The calculator rearranges the BMI formula to solve for weight at the two BMI boundaries that define the normal weight category — 18.5 and 24.9 — giving a lower and upper healthy weight bound for your height.

Formula & methodology

Minimum healthy weight = 18.5 × height (m)². Maximum healthy weight = 24.9 × height (m)².

Worked example

For a height of 170 cm, the healthy weight range is about 53.5 kg to 72.0 kg.

Important notes

—This range is derived purely from height using the BMI method — it does not account for muscle mass, frame size, or body composition.
—For a broader perspective, compare this range against the Ideal Weight Calculator, which uses separate clinical formulas.
