The height of a 12-year-old can vary widely depending on factors such as genetics, nutrition, and overall health. On average, a 12-year-old boy is about 58 to 62 inches (147 to 157 cm) tall, while a 12-year-old girl is typically around 59 to 63 inches (150 to 160 cm) tall.
It’s important to note that these are just averages, and children grow at different rates. Some may be taller or shorter than these ranges and still be perfectly healthy. If you have concerns about your child’s growth, it’s always a good idea to consult with a pediatrician.
