YouTube channel art should be 2560×1440 px. The safe zone visible on all devices is the central 1546×423 px. Keep important text and logos within this safe zone.
Why is my YouTube thumbnail blurry?
Blurry thumbnails are usually caused by uploading a low-resolution image (under 640 px wide) or an oversized file that YouTube has re-compressed heavily. Always start with a 1280×720 source at 85%+ quality.
