How much do you weigh? It comes down to weight more than height. If you're 160 or less, then the board will be fine. It might feel a little small at first, but you can adapt. 170 or bigger, then I'd suggest a longer board.
I'm 6' 2" 170 lbs. I ride a 163 for all mountain (little bigger than it needs to be) and looking to get a 159 for freestyle/some park.
Either way, it's completely ride-able. It would just be more comfortable for you to learn on if it were longer.
Hope I helped.
If you want to be a chick, a dude, a tent, or a velociraptor be my guest, but if you choose the last one you bet your ass I will have a spaz-12 to your face.
