“Ideal weight” isn’t a single fixed number — it’s a range that depends on your height, age, sex, and frame size, which is exactly why formulas like Devine, Robinson, and Hamwi exist and sometimes give slightly different answers. This ideal weight calculator gives you a realistic target range rather than a single arbitrary number pulled from an outdated chart.
It’s worth remembering that ideal weight calculations don’t account for muscle mass, so an athlete may fall outside the “ideal” range while still being in excellent health — pairing this number with a body fat percentage calculator gives a much more complete picture. If your goal is weight management specifically, our TDEE calculator and our guide on TDEE vs BMR can help you build a realistic calorie plan around your target.
Enter your height, age, and sex above to see your ideal weight range and use it as one data point among several for your health goals.
