BMI (Body Mass Index) is a widely used screening measure that relates body weight to height. It can be a quick reference for comparing where someone falls relative to population weight ranges, and is commonly used in clinical and research settings.
The “ideal weight range” shown here is simply the weight range that corresponds to a BMI of 18.5–24.9 for your entered height — the range defined as “Normal” by the World Health Organization. It is a statistical reference, not a personal target or recommendation.
