Your Twitch channel banner (also called the header or offline image) is the large graphic that fills your channel page when you are not live. A professionally designed banner at the correct dimensions makes your channel look established and inviting to new visitors.
Twitch Banner Dimensions
Twitch channel banners display at 1200×480 pixels. The platform recommends uploading at 1920×480 pixels to account for ultra-wide monitors. The file size limit is 10MB, and accepted formats are JPG and PNG. Avoid using very fine text — the banner is often viewed at reduced sizes.
How to Crop for Twitch Banner
Open imgresizr.com and upload your banner image or artwork. Use the Crop tool and manually set the crop dimensions — the 2.5:1 aspect ratio means you need a wide, panoramic crop. Aim to get the most visually balanced composition within this wide frame. After cropping, resize to 1920×480 pixels and download as PNG.
Twitch Banner Content Ideas
- Channel artwork featuring your gaming persona, avatar, or branding colours
- Your streaming schedule showing days and times you go live
- Your social media handles for followers to find you off-platform
- Game artwork or a collage from the games you stream
- A call to action like "Follow for live streams Mon, Wed, Fri"
Twitch Banner Design Tips
- Keep the most important content in the centre-left — profile info overlaps the right side on some views
- Use consistent colours, fonts, and art style that match your panels and overlays
- Test how the banner looks on desktop, tablet, and mobile — Twitch scales banners differently across devices
Resize the banner using imgresizr.com, then upload it in Twitch Studio under Channel Settings. A consistent, well-branded Twitch channel attracts followers and sponsors more effectively.
