Calculate Your BMI
Enter your height and weight below. Your BMI is a screening measure and does not, by itself, diagnose your health or body composition.
Your BMI Result
For adults aged 20 and older, common BMI categories are: below 18.5 (underweight), 18.5–24.9 (healthy weight), 25.0–29.9 (overweight), and 30 or higher (obesity). BMI categories are not intended for children and teens, who need age- and sex-specific assessment.
Health note: This tool is for general information only, not medical advice. BMI does not distinguish fat from muscle and may not accurately reflect health for every person. Speak with a qualified healthcare professional about your individual results.
