Windshield Wiper Replacement

Hey all! I just got a 2013 RRE. However I noticed that the wipers were not doing an excellent job and I want to replace it just in case... one day the sky gods decide to offer us some rain!

I was wondering... what are the measurements of the wiper blades? I read somewhere that it's 22" for both sides, while some other sites say its 21" and 24".

Also, do you guys have any brands you recommend? I'm currently looking at Valeo 900.
Thanks!

I used the Trico Exact Fit wipers this past time. They fitted straight onto the wiper arms out if the box without having to try and figure out which was the right connector. The blades are different sizes however - drivers side (USA) is 24" and I think you can put 21" or 22" on the passenger side.
