Disclaimer: This tool provides informational results only and should not be used as professional advice.

The Ideal Weight Calculator estimates the adult weight range corresponding to BMI 18.5 through 24.9 at a selected height.

$\text{Weight}=\text{BMI}\times\text{Height}^2$

The result is a height-based screening range, not one correct weight for every body.
