This question is difficult to answer because there are a lot of variables involved in selecting the right length for you. The two biggest factors are snow conditions and your weight, including any pack/gear you may be carrying. It is best to wear the shortest shoe that will still provide you with enough flotation. The shorter the shoe, the easier it is to maneuver. One of the nice things about the Denali Ascent™ and Denali Classic™ snowshoes is that you can purchase a short length – 22 inches – and add optional extension tails as needed.
