This reference collects Twitch’s main ad placements with the exact dimensions, file-size caps and copy limits for each one. Twitch sells a mix of display units, in-player video, and premium homepage takeovers, and each has its own creative constraints — getting them right avoids rejected uploads and stretched creative.
How it works
Pick a placement and the tool reads its spec from a built-in table covering resolution, aspect ratio, maximum file size, and (for video) duration and delivery format. Display units like the medium rectangle and leaderboard are fixed-pixel static slots, so the resolution is exact. Video placements use the player’s 16:9 frame and are sold in standard 15 and 30-second blocks.
The headline and supporting-copy limits shown for sponsored and headliner units reflect the short character budgets Twitch reserves so brand copy fits the on-screen card without truncation.
Tips
- Always export display banners at their exact pixel size — Twitch does not scale static units, so off-spec creative is rejected.
- Keep video ad logos and key messaging in the central area; the 16:9 player can letterbox on some devices.
- Confirm final codec and bitrate with your ad partner before delivery — programmatic buys sometimes tighten the spec.
