What page width for the new 7.2?

With the new model evo, what is the ideal width page? 1600? Thank you for your opinion ...

Whatever you want the max width to be. The Evo template is responsive, so smaller screens will handle it fine.

Best would be where text in the buttons would adjust properly with out changing the column's length in desktop view. 

thank you for your opinion, I have a little tested in 1600, it is true that it works very well on all screens.
