I'm a well read grad student who's bluntly honest about all things, although I try to be most honest about myself.
Rocket's said to be four feet high. He seemed shorter to me in the movie.

Gamora, Star-Lord, Rocket, Drax, Groot.
Groot is incredibly tall, but Quill - Star-Lord - is average height. If Rocket is four feet, than Quill is over eight.
Nope.
Chriss Pratt is 6.2, which would make Rocket closer to three as Quill is about twice Rocket's height.
I... wow... that's just wrong. And I feel kinda like I'm geeking out about this.
