The Twitch Offline Banner size (1920×1080px)
The Twitch offline banner is the image that fills your channel's video player when you are not live, and Twitch recommends 1920x1080 pixels at a 16:9 ratio so it exactly matches the player's dimensions. This is prime real estate: anyone who visits your channel between streams sees this screen first, so it is your chance to show your schedule, socials, latest content, or a simple be right back message instead of a blank black box.
Sizing to a full 1920x1080 means your banner fills the player edge to edge with no letterboxing on desktop, and the 16:9 shape is the same format as your actual stream, so the transition from offline screen to live feels seamless. At this resolution text and logos stay crisp on large monitors, which matters because a pixelated offline screen is the first impression many potential followers get of your channel.
Design it to work as a mini landing page: keep vital information like your streaming schedule and social handles inside a safe central area, since Twitch overlays some player controls and the layout can crop the edges slightly on different screen sizes. Strong, on-brand visuals that match your panels and overlays make the whole channel feel cohesive. Everything here resizes 100% in your browser with no upload and for free, so your art stays private on your device. Twitch updates player and layout behavior over time, so verify the current recommendation before finalizing your offline screen.
