I am 5'8 and 14 years old how tall will I be when I am older?

Predicting adult height based on current height and age involves several factors, including genetics, gender, and growth spurts. For boys, a common method is to add the father's height to the mother's height and then add 5 inches, then divide by 2. For girls, subtract 5 inches instead of adding. However, these are rough estimates and individual growth patterns can vary significantly. Regular monitoring of growth and development by a healthcare provider can provide a more accurate prediction.
