I do not know what they say, but YouTube art for desktop is only roughly the size of a web banner. If you make a wallpaper like YouTube channel art, only 10 % of it will be visible in laptops and desktops.
That is because YouTube channel art format is different. They use a single image for TV, PC and mobile devices. Which in my opinion is challenge for the end users.
Use the above image as base for building your channel art. Whatever comes in the blue area will be used for PC and mobile devices and the white area will be for the TV. I hope this will work for you. Let me know if you are get into any bottlenecks.
Finally, go that one right. All you could actually make is a small banner. Unless you are making the art for the TV. And I hate the part where I had to centre it so that it won't be auto trimmed. But all good so far. I got the dimensions right and managed to redesign the whole concept in such a way that it fits into the art template.
