The Reddit Profile Banner size (1920×384px)
The Reddit profile banner is a wide 1920x384 pixel header at 5:1 that runs across the top of your user profile page. It is the backdrop behind your username and avatar, giving your profile a bit of personality on a platform that is otherwise text-heavy and community-focused.
Because the banner is short relative to its width and the visible height changes between desktop and the Reddit app, keep any important content within a centered safe zone. Your avatar and username sit over the lower-left area, so avoid placing key graphics or text there where they would be covered or cropped.
This slim 5:1 strip is not the place for detailed artwork or fine text, which get lost. A clean horizontal design, a pattern, a landscape, or a simple brand element that reads across the width, works best. Upload at exactly 1920x384 so Reddit does not stretch your banner, and keep it uncluttered so it complements rather than competes with your profile content.
