Estimate Your Ideal Weight from Height

The Helperzy Ideal Weight Calculator estimates a healthy weight range for your height and gender using several well-known medical formulas — Devine, Hamwi, Robinson, and Miller. Enter your height and see all four estimates at once so you can compare. Each formula was originally developed for a specific clinical purpose, and they produce slightly different figures. Seeing them together gives a range rather than a single magic number, which is more honest since ideal weight varies with body composition, frame size, and individual factors that a formula cannot capture. People use it to set a general target for weight management, to understand what the medical literature considers a healthy range, and as a starting point before consulting a professional. It is not a prescription — body composition matters more than a number on a scale. Everything runs in your browser, so it is instant, free, and works offline once loaded.
