Notes:
- Early Childhood (1-5 years): Boys and girls grow at very similar rates during early childhood. There’s little variation between them at these ages, as both genders generally fall into the same height and weight ranges.
- School-age (6-10 years): Boys start to pull ahead slightly in height and weight during this period, although the differences are not too pronounced. Girls may show growth spurts around ages 9-10 as they approach puberty earlier than boys.
- Pre-adolescence and Adolescence (11-15 years): By around 11-12 years of age, girls usually surpass boys in both height and weight due to their earlier onset of puberty. Boys, however, catch up and typically surpass girls in height and weight by around age 14 or 15.
- Late Adolescence (16-18 years): Boys continue to grow into their late teens, reaching their adult height and weight later than girls. By age 18, boys are typically taller and heavier than girls on average.
Gender Differences:
- Puberty: The timing of puberty creates the most significant differences between boys and girls in terms of growth. Girls usually experience growth spurts earlier, around ages 9-12, while boys have their growth spurts later, around ages 12-15.
- Final Height and Weight: By age 18, the average boy tends to be taller and heavier than the average girl, with boys reaching final heights in the range of 64-72 inches (162-183 cm) and girls typically reaching 63-69 inches (160-175 cm).
