Twitch video thumbnail size: the 2026 spec
This guide covers the official spec, format requirements, and the practical workflow imgsize.cc uses to get it right in your browser.
Why these dimensions
Twitch video thumbnails render at 1920×1080 on the video page and 16:9 in search results. The recommended upload matches this exactly. Twitch supports custom thumbnail uploads.
Crop the central content of your image to the central 80% of the frame. Twitch Thumbnail may crop or overlay UI elements near the edges, so critical content should stay well within the safe zone.
Common mistakes
Off-center subject — gets cut in the search list
Text near the edges — illegible at thumbnail
Frequently asked questions
Does Twitch pick a frame automatically?
Yes, but the auto-pick is rarely the best frame. Upload a custom thumbnail for higher CTR.
How imgsize.cc handles it
