Sorry for copy and paste but this is really helpful and will save you a lot of time posting a thread and checking back.
Go there, find your skis or the skis you want and click on them and on the right side of the page that pops up is a little symbol that says "Sizing Chart". Click it and a chart with all of the skis of the brand of the ski that you have picked pops up. Find your ski and its length and it will tell you the length of the ski in feet and inches, the recommended weight, recommended height, skier ability, and conditions to ski it on.
-Hope this helps anyone in the market for new skis.
What skis are you looking for?
Alright copy and paste that into the url and pick the brand on the left hand side. Find your ski and click it. On the page that comes up with the picture of the ski and the description specs reviews etc. on the bottom, there is a little icon right under add to cart that says "Sizing Chart" Click it and find your ski and length. I'm sorry but that is as descriptive as I can get about it. Maybe I failed at this thread and the website that it implies.
