Ideal Weight Calculator

How this tool works

Compares Devine, Robinson and Miller formulas for adults at least 5 feet tall. Despite the conventional tool name, there is no single ideal weight for everyone. The displayed BMI range is a screening reference, not a prescription. For adults aged 20–100. These are educational estimates, not diagnoses, treatment targets or medication-dosing guidance. They are not designed for children, pregnancy or breastfeeding; body composition and health conditions can make the estimates unsuitable. Discuss personal concerns with a qualified clinician.
