YouTube channel art (banner) should be uploaded at 2560x1440 pixels, though different portions are visible on different devices. The safe zone for text and logos is approximately 1546x423 pixels centered within the full image.
YouTube displays the banner differently across devices: TVs show the full 2560x1440 area, desktops show approximately 2560x423, tablets show about 1855x423, and mobile devices show roughly 1546x423. Design your banner so it looks good at all crops.
To create YouTube channel art with ImgTools, upload a large source image, crop to include all important elements within the 1546x423 center safe zone, and resize to 2560x1440. Consider layering your design so the background extends to the full area while key elements remain centered.
Save as JPEG at 90% quality. YouTube accepts files up to 6 MB. PNG format works well for banners with text and sharp edges.
