What is how tall should a 13 year old girl be?

The average height for a 13-year-old girl is approximately 5 feet 1 inch (155 cm). However, the height of a 13-year-old girl can vary greatly depending on a number of factors such as genetics, nutrition, and physical activity level. It is important to note that every individual's growth pattern is unique, and deviations from the average height should not necessarily be cause for concern.
