What is the average girl height ?
it depends on age, family history, ethnicity. there are too many factors to give you a number
Depends what country. If it's European and American around 5'6" or 5'7", if it's a 3rd World Country it'll be much shorter usually.
5'6" is good
i agree with kyrslips
the average usa height is 5"4 if your a girl, if your taller than that, then you are taller than the national average.
Cool spot is right. The average heights of male and female are posted by AMA. currently it is 5' 4" for a female and don't ask me the weight it would be rude to say that.
