How to use the Ideal Weight Calculator
- Choose your sex.
- Enter your height in centimeters or inches.
- Compare the formulas and the healthy BMI range.
Why there are several formulas
“Ideal body weight” formulas were created for medication dosing, not appearance. Devine (1974), Robinson (1983), Miller (1983) and Hamwi (1964) all start from a base weight at 5 feet and add a fixed amount per inch, so their answers differ by a few kilograms. The healthy BMI range is wider and usually more useful.

Frequently asked questions
Which ideal weight formula is best?
None is “right” for everyone. Robinson and Miller tend to give lower values than Devine and Hamwi. Treat the spread and the healthy BMI range as a guide, not a target.
Do these formulas work for very short people?
They are designed for adults over 5 feet (152 cm). Below that, use the healthy BMI range instead.
Is anything I enter saved or sent?
No. The calculation runs in your browser. Your last inputs are remembered on this device only, so the page opens where you left off.
Can I install Ideal Weight Calculator as a web app and use it offline?
Yes. Ideal Weight Calculator is an installable web app (PWA) — installed from your browser, not downloaded from an app store. Click Install app at the top of this page in Chrome or Edge (Windows, macOS, Linux, ChromeOS) or on Android, use Share → Add to Home Screen on iPhone and iPad, or File → Add to Dock in Safari 17+ on a Mac. It then opens in its own window with its own icon, and because it runs entirely in your browser it keeps working offline. Firefox on desktop can’t install web apps. How installing works.
