Determining the perfect ski size depends on a number of things. Factors such as height and weight provide an excellent starting point but there are other things to consider. Ski category, snow type, terrain and personal preference are just some of the things to take into account. The general rule is to pick a ski length that is somewhere between your chin and the top of your head. Advanced and expert skiers may chose skis that are slightly longer than head height. Besides, shorter skis make taking turns easier, but they are less stable at high speed.
