Many teens worry about their weight. According to the Center for Disease Control, healthy teens should not measure weight exclusively but also take into consideration body mass index. Healthy weight ranges fall between the 5th and 85th percentile on a BMI chart.

The American Academy of Pediatrics also recommends using BMI beginning at two years of age to screen for overweight or obesity issues. BMI screenings indicate possible concerns, but additional assessments, including diet evaluation, skin fold thickness, family history, physical activity and health screenings, determine if there is a true problem. The website TeenHealth offers a tool which allows teens to input their gender, date of birth and present date, weight and height to chart their own BMI.
