Most of my kilts fall between mid knee to the top of the knee cap. A couple of my kilts are the shorter "hipster" cut and if I cinch my belt too tight they ride up above the knee which makes me feel a bit silly. My workmans Utilikilt is cut longer and falls below the knee, which feels almost as strange to me as too short. I don't think it's a tradition thing with me though, it's just what feels right.
