⚖️Ideal Weight Calculator
Enter your height to see what Devine, Robinson, Miller, Hamwi, and the BMI healthy range each suggest — displayed as a range of reference estimates, not a single target.
This tool is a general reference and is not medical or dietary advice. "Ideal weight" is not a fixed target — formula estimates vary, and none accounts for body composition, muscle mass, frame size, age, or individual differences. Please consult a registered dietitian or physician before making any decisions about your weight or health. If you find yourself preoccupied with your weight or body, consider reaching out to a qualified professional for support.
Free Ideal Weight Calculator Online
Curious what the well-known "ideal weight" formulas say for your height? Our free Ideal Weight Calculator shows them side by side. Rather than handing you one number, it presents a range of reference estimates — from the classic Devine, Robinson, Miller, and Hamwi formulas — alongside the healthy-weight range based on BMI for your height, so you can see how much they differ.
And they do differ, which is the point. Most of these formulas are decades old and several were originally created for medication dosing, not as health goals. None account for muscle, body composition, frame size, or individual differences. "Ideal weight" is really a misnomer — there's a healthy range, not a single correct number. This tool is a factual reference for understanding what those formulas produce and why to read them with healthy scepticism.
Simply enter your height to see the range instantly. No sign-up, no downloads, no limits. For anything about your own weight or health, please speak with a doctor or dietitian.
