As we don’t currently have banner art I’ve decided to go to the community. The community decides the winner by upvoting the banners they want to see. It doesn’t matter if you’re amazing at art or not we welcome all artists. Now get out there and create your art! It will end in a week.
I went to another communities Banner competition, and all the submissions seem to be 730 x 280 pixels. I couldn’t find anything in the documentation about banner sizes.
From what I’ve tested most banner sizes work I just tried 4k and it works perfectly
