I'm playing on PC, on a 3-4 year old screen so it's not that big. With party members left, mini map right top, chat bottom left, my hp left top and boss hp mid top, my skills are mid bottom, 3 rows, and its starting to get cluttered. I love the option to hide Duty lists while in a duty, gives me a lot more space to look right/re-position myself, but more skills would end up being click for me, as my 1 till = are full, as are my shift+1-5 and ctrl+1-5....
