About the Ideal Weight Calculator

The Ideal Weight Calculator shows ideal body weight from four established formulas — Devine, Robinson, Miller and Hamwi — plus the healthy BMI range. It runs as plain JavaScript inside the page, which means there is no upload step, no queue and no size limit imposed by a server — the only limit is your own device.

What people use it for

  • Getting a target range rather than one arbitrary number.
  • Comparing the older clinical formulas against BMI.
  • Setting a sensible goal weight.
These formulas were developed for drug dosing, not aesthetics, and they disagree with each other by several kilograms. A healthy weight is a range, not a point.

Frequently asked questions

Do I need an account to use the Ideal Weight Calculator?
There is no cost and no cap. The Ideal Weight Calculator is not a demo of a paid product, so nothing is held back or watermarked.
Is my data uploaded anywhere?
No. The Ideal Weight Calculator runs entirely in your browser using JavaScript. Nothing is transmitted, logged or stored, which you can verify yourself in the Network tab of your browser's developer tools.
When would I actually need the Ideal Weight Calculator?
Typical uses: getting a target range rather than one arbitrary number. Comparing the older clinical formulas against BMI. Setting a sensible goal weight. It is built for exactly those cases rather than being a general-purpose tool with this bolted on.
What do people usually get wrong here?
These formulas were developed for drug dosing, not aesthetics, and they disagree with each other by several kilograms. A healthy weight is a range, not a point.
Is the number rounded?
The calculation runs in double precision and the result is shown to ten significant figures, so converting a value and converting it back returns the original. What is displayed is rounded for readability; what is copied is not.
