Why not just disregard height and go as who you want?
I wouldn't usually care, but most of the characters I want to go as are tall boys. (Kurogane from Tsubasa, Harima from School Rumble etc.) I was told I would make the character look chibi.
But thanks, I'll probably ending up going as who I please.
You could PURPOSEFULLY go as chibi versions! That's always fun! XD But I agree, most anime girls are short. If you're looking for guys, look for the younger boys. Off the top of my head I can think of Ash from Pokemon, Goku from Saiyuki, Shuuichi from Gravitation, Daisuke or Satoshi from DNAngel, etc etc. I'd suggest just looking through your favorite anime/manga for characters you wouldn't mind cosplaying. ^^
