Twitter GIF dimensions and file-size rules affect how reliably your GIF posts and displays across the platform. To maximize reach and avoid cropping or compression issues, you need the correct pixel sizing, aspect ratios, and export settings. This guide explains optimal Twitter GIF dimensions, supported formats, and practical steps to prepare GIFs for profile headers, posts, and replies. Read on to align your assets with platform rules and keep visuals consistent over time.
Recommended Twitter GIF Dimensions and Aspect Ratios
For consistent display on Twitter, use these dimension guidelines:
- Profile header GIF: up to 1500 x 500 px, 3:1 aspect ratio, keep important content within the visible center area.
- In-post GIF: 1280 x 720 px (16:9) is ideal; 1080 x 1080 px (1:1) and 1080 x 1920 px (9:16) also work well for full-screen mobile viewing.
- Maximum file size: 15 MB for GIFs; note that large files may be compressed or converted to video.
Aspect Ratio Notes
X supports 16:9, 1:1, and vertical 9:16. While 16:9 fits timelines uniformly, 1:1 and 9:16 can appear larger in the media shell and may reduce context loss on smaller screens.
