Seems a little short to me, but I like my skis longer than most. I am 5'9" and wont ride anything shorter than a 179.  The general advice for ski length, is if you are a beginner your skis should fall between your chin and nose, intermediate should fall between your nose and eyebrows, and advanced between your eyebrows and the top of your head, if you like that. Keep in mind too with alot of the park skis that are rockerd  pretty hard, that the skis will ski substantially shorter than their true height. I have the 179 K2 press, and they come off the snow a good 6 inches or so before the tips and tails.
