The range is calculated from your height using the general adult BMI interval of 18.5 to 24.9. It is a broad screening range, not a personal medical target, and it does not directly measure muscle, fat distribution or health status.
The calculator divides height by wrist circumference to estimate a small, medium or large body frame. It applies a −10%, 0% or +10% adjustment to the formula median, then keeps the result within the broad healthy BMI range. This frame method is approximate.
The tool shows Devine, Robinson, Miller, Hamwi and Lemmens reference weights. It uses their median where the traditional height-based equations apply. Age is used to keep the tool for adults and tailor context; it does not create a precise age correction. All calculations run locally in your browser, with no API request or stored profile.
This calculator provides general educational estimates only. Ideal-weight formulas and BMI are screening references, not diagnoses, and may be unsuitable during pregnancy, for athletes, older adults, people with significant muscle mass, or people with medical conditions affecting weight. Consult a qualified healthcare professional before making major weight, diet or treatment decisions.
