What matters
YouTube End Screen dimensions at a glance
End screen graphics sit behind clickable YouTube elements, so they need clean negative space and a layout that supports overlays rather than fighting them.
Building the asset at 1920×1080 lets you preview where clickable buttons and channel links land. It keeps the background sharp during the final seconds.
Cramped artwork or wrong ratios mean interactive elements cover text, faces, or product shots, making the end screen cluttered and hurting follow-on clicks.
