Every time I upload a header to my YouTube channel, it looks fine on desktop but gets cut off on mobile. Is there a universal size or layout that works across all devices?
I had the same issue until I found out that the proper youtube header size is 2560×1440 px. But the real secret is the 1546×423 px safe zone in the center—that’s the only area visible on every screen. I redesigned my header with that in mind, and now it looks sharp and perfectly aligned on all devices.
