2,560 x 1,440 pixels is YouTube's recommended banner (channel art) size. Because the same image displays differently across TV, desktop, and mobile, YouTube defines a 'safe area' of roughly 1,546 x 423 pixels in the center - keep your logo and text inside that zone so nothing important gets cropped on smaller screens.

800 x 800 pixels, uploaded as a square. It displays as a circle across YouTube, including next to your videos and comments, so keep your logo or face centered.

1,280 x 720 pixels at a 16:9 ratio is the standard custom thumbnail size. This matches the video player's aspect ratio and stays sharp across devices.

2,048 x 1,152 pixels. Uploading below this gets stretched and looks visibly softer, especially on larger screens.
