What is is 5 5 tall for a 12 year old?

It depends on the gender and ethnicity of the 12-year-old. However, on average, a 12-year-old boy in the United States is around 4 feet 10 inches (147 cm) tall while a 12-year-old girl is around 4 feet 11 inches (150 cm) tall. Therefore, a 5'5" height for a 12-year-old would be considered quite tall, especially for a girl. It is recommended to consult a pediatrician for a more accurate assessment of a child's growth and development.
