Estimate a healthy target weight for your height using several established formulas so you can see a sensible range rather than a single number. Enter your height and sex and the calculator shows the ideal body weight from the Devine, Robinson and Hamwi equations, which doctors have used for decades, together with the weight range that corresponds to a normal BMI for your height. Because these formulas were built for different purposes they give slightly different answers, and viewing them side by side gives a more realistic sense of a healthy target. Ideal weight is a rough guide that ignores build, muscle and frame size, so treat it as a reference point, not a strict goal. Everything is computed locally in your browser.
