Our free BMI calculator for teens (ages 2-19) helps assess healthy weight and track growth. Essential for parents and adolescents to understand weight relative to height and age, promoting healthy habits. Use CDC standards for accurate Body Mass Index calculation and identify potential concerns.
Formula:
The Body Mass Index (BMI) for teens is calculated using the standard formula, but its interpretation requires age- and sex-specific growth charts from the CDC. The formula is:
BMI = weight (kg) / [height (m)]²
Alternatively, if using imperial units:
BMI = [weight (lbs) / [height (in)]²] * 703
Where:
- Weight: Body weight in kilograms (kg) or pounds (lbs)
- Height: Body height in meters (m) or inches (in)
