Answer:
I don't really think they're SHOULD be an average height, it just makes us all seem normal or abnormal, and start comparing ourselves!. I would imagine, around 5'3. I'm 5'7 and 13, so I think it all depends on genetics. If your petite, it shouldn't matter, if your tall, it shouldn't matter!. Of course I get called lanky, then and again but I just laugh because they're just sad, pathetic losers!. Be who you are, and love it!!
