the average age to stop growing is mid twenties.

This is the worst answer I have ever seen!

Girls usually stop growing about the age of 14/15.

Boys can stop growing anytime from 16/21.

Boys and Girls it depends on the genetic make up of the family. Ask your parents. Look at the average sizes of everyone in the family, not just Mom and Dad but Grandma and Grandpa, Aunts and Uncles. Girls when you are 13 and have not started your cycle yet you will soon and you still have a couple years of growing. Boys, you will grow all through your high school career, so buff up and grow up. After about 21 there is no more growing up for you. However if you have shorty's in your family you might be done growing by 16/17. Girls can too, however normally a girl stops growing shortly after starting their menstrual cycle. About a year or two.

Finally..Pay attention to your family and ask questions. That is when you will know when you will quit growing. Scientifically, Girls--14/16. Boys--16/21.
