Body Weight: Males, Age 3

What these numbers mean

A value around 15.5 kg (34.2 lb) is typical (50th percentile) for boys in this age group. The middle 50% of the reference population fall between about 14.6 kg (32.2 lb) and 17.5 kg (38.6 lb); values below or above that central range sit in the lower or upper half of the distribution.

Ages 20 and over are measured US population percentiles from NHANES 2021-2023. Ages 2 to 19 are from NHANES 2015-2018, by single year of age at examination, with 114 to 249 children measured per age and sex. Because weight alone does not account for height, percentile position is not a healthy-weight category.
