BMI Teen Calculator

Maintaining a healthy weight is crucial for teenagers as they undergo rapid growth and development. Our BMI Teen Calculator is a simple, accurate, and free online tool designed to help teens and parents monitor body mass index (BMI) and understand weight-related health risks.

With this calculator, you can quickly determine if a teen falls under underweight, normal, overweight, or obese categories and receive personalized advice for a healthier lifestyle.

What is BMI and Why It Matters for Teens

BMI, or Body Mass Index, is a numerical value derived from a person’s weight and height. For teens, BMI is used as an indicator to assess whether their weight is appropriate for their age and height. It is an essential measure because:

  • It identifies potential health risks associated with underweight, overweight, or obesity.
  • It helps track healthy growth patterns during adolescence.
  • It supports preventive care by guiding nutrition and exercise choices.

Unlike adults, teen BMI is interpreted using age- and gender-specific percentiles, reflecting the rapid changes in body composition during adolescence.
