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.
