For adults aged 20 or older. BMI is a screening measure, not a diagnosis or a personal weight recommendation. Example values are editable. Measurements stay in your browser.
BMI does not distinguish muscle from body fat and may be unsuitable during pregnancy or for individual clinical assessment. Category thresholds use the unrounded value. Discuss health and any weight-change goals with a qualified clinician.
