Ideal Weight Calculator

You enter your height and sex, and it runs four well-known ideal weight formulas at once, then shows a healthy weight range from your BMI. The formulas all start from your height over five feet and add a set amount per inch, so they land close together but not identical. Everything runs in your browser, so you'll see the numbers update as you type, and nothing you enter leaves your device. It's a quick read, not a verdict.

There isn't one perfect number, so it's better to think in a range. A common healthy band comes from a BMI of 18.5 to 24.9 for your height, and the classic formulas land somewhere inside it. For a 5 foot 10 inch man, the formulas sit around 155 to 165 pounds, while the BMI band runs roughly 129 to 174 pounds. Where you fit depends on your build, muscle, and health, so don't treat a single figure as a target.

They're four ideal body weight formulas built for medicine, mostly to help dose medication, and each adds weight per inch over five feet. Devine is the most widely used: a man starts at 50 kg and adds 2.3 kg per inch, a woman starts at 45.5 kg. Robinson and Miller give slightly lower figures, and Hamwi gives slightly higher ones. None of them account for muscle or frame, so the calculator shows all four plus a BMI range to give you the fuller picture.

Not exactly, and that's worth knowing. The old formulas give a single tidy number, but real bodies vary, so health professionals lean on a healthy weight range instead. Someone muscular can sit above their formula weight and still be healthy, while frame size shifts things too. Use the BMI range here as the broader guide and the formulas as reference points, and remember that weight is only one signal among many that matter for your health.

Yes, just pick your sex and the formulas adjust. Every formula starts women a few kilograms lower than men at five feet and adds a little less per inch, so a woman's ideal weight comes out below a man's at the same height. The healthy BMI range, though, depends only on height, so it reads the same for both. If you're well outside these numbers in either direction, it's worth a chat with a doctor rather than chasing a formula.

Yes, it's completely free, with no sign-up, and it runs right in your browser, so nothing you enter leaves your device. Type your height, pick your sex, and read your range in pounds and kilograms in a tap. Bookmark it as a quick reference, but treat the result as a ballpark, since a calculator can't see your muscle, frame, or health history the way a doctor can.
