What age do humans stop growing?
There is no exact science as to when humans stop growing. Females very frequently stop growing by the time they are around 18 and males around 21. However, there continues to be bone growth that does not add to height. In particular, the sutures between the bones of the skull do not completely grow together until about the age of 29. Frequently females slow or stop growing soon after they have their first menstrual period. So, as I said in the very first sentence, there is no exact science as to when humans stop growing. The use of generalities on this topic is far more accurate than absolutes.
