Pediatric BMI Chart

Pediatric BMI is calculated using the same formula as adult BMI: weight in kilograms divided by height in meters squared (kg/m²). However, its interpretation for children and teens differs due to age and sex.

BMI percentiles rank a child's BMI relative to their peers' BMI (same age and sex). For example, a BMI in the 60th percentile means the child's BMI is higher than 60% of children of the same age and sex.

Pediatric BMI should typically be checked annually during well-child visits, starting at age 2. More frequent assessments may be needed if there are concerns about a child's growth or weight.
