About Child BMI Percentile
Child BMI is age- and sex-specific because body fatness changes substantially with age. The CDC uses BMI-for-age percentile charts to classify weight status in children aged 2–19. Percentile indicates how a child's BMI compares to peers of the same age and sex.
CDC BMI-for-Age Categories

| 5th – 84th | Healthy Weight (5th–84th %ile) |
| 85th – 94th | Overweight (85th–94th %ile) |
| 95th and above | Obese (≥95th %ile) |
