Introduction
Normal height for boys in the first year of junior high school is typically between 154.3 and 168.8 cm, with an average height of approximately 159.5 cm. For girls, the normal range is usually between 144.2 and 164.3 cm, with an average height of about 156.3 cm. If a child around 13 years old falls within or near the average or median of these ranges, their height is generally considered reasonable. However, if their height is below this range, it may require closer attention.
The average height for boys in the first year of junior high school is usually around 159.5 cm, while for girls it is typically about 156.3 cm. A detailed analysis is as follows:
Students in their first year of junior high are generally around 13 years old, a period characterized by rapid physical development. There is no strict standard for height at this age. Boys typically range between 154.3 and 168.8 cm, with an average height of approximately 159.5 cm. Girls usually fall between 144.2 and 164.3 cm, averaging around 156.3 cm. A height near or within these average or median ranges is generally considered normal for a 13-year-old. If height falls below this range, caution is advised.
If a child's height is significantly below that of peers, it is recommended to visit an orthopedic specialist at a hospital to rule out potential pathological conditions.
