Height is often times a preference sort of thing. However, a general rule with skates on, a forward would have the stick be just under the bottom of your chin. Defenseman, closer to the mouth or just below the nose. Preferences can of course be in between the two, or it could go outside the range ( even shorter or longer that what i stated). Shorter sticks are better for stick handling, longer is harder for stick handling, but give yous reach for forward take aways or defenseman blocking shots or chipping pucks away. I'm 6'4 and play D, i used to use a stick up to my nose, but my god it was horrible for stick handling. Over the years i slowly cut it down and have it just below my lower lip. Still plenty of length and reach being tall, but it has seriously helped with my stick handling abilities. Just my 2 cents as a beer leaguer now.
