About BMI Calculator
BMI Calculator estimates body mass index from height and weight. For ages 2 to 19, it uses CDC BMI-for-age percentile data by sex and age; for ages 20 and older, it uses the familiar adult BMI categories. It also shows a healthy weight range for the entered height so you can quickly compare the current value with a common reference band.
How To Use It
Choose the measurement system first so the height and weight fields match the units you want to enter, then enter age because the calculator uses different rules for ages 2 to 19 and ages 20 and older.
- Choose metric or imperial mode.
- Enter gender, age, height, and weight.
- Click Calculate BMI to see the BMI score, category, and healthy weight range. Ages 2 to 19 also show a BMI percentile.
Examples
