dimensions

Hey guys, I was wondering if anyone knew what the dimensions of the YouTube silver play button frame are? Cheers, Ned

I try the 2560 by 1440 and the 2048 by 1157 dimensions and it cuts out a whole bunch of stuff on the desktop and even worst if its on your phone. Perdy p****d lol What do you use that will display nice on desktop? Also is there a way to customize each dimension and banner art for TV, desktop...
