Maybe it does though. Maybe the reason I'm getting away with a shorter relative stance for my height is because I am riding a board that is possibly too short and soft for my height and weight (using a 164 all mtn/freestyle). If I were smaller, I might have to go wider in order to have better control of the tip and tail. Or if I went to a longer, stiffer snowboard I'd have to widen my stance more. I'm sure someone with a much better understanding of this would have the answer.
I didn't really put a ton of thought into selecting my width. I closed my eyes, hopped onto the board and landed in my natural athletic stance and measured it. It happened to be 23 inches. I've gone to 24 but it just isn't comfortable.
