Single image tweet — 1200×675px (16:9)
A single attached image displays at a 16:9 ratio in the feed (showing approximately 1200×675px). Upload at 1200×675 for exact fit. Twitter also accepts portrait images — these display at approximately 2:3 in the feed, showing 1200×1800px. Both show cleanly without cropping.
Two image tweet — 1200×600px each
Two images display side by side, each at approximately a 2:1 ratio. Upload both at 1200×600. Keep key content central in each image — Twitter may crop the edges slightly.
Four image tweet — 1200×600px each
Four images appear in a 2×2 grid. The two left images are taller than the two right images in display. Upload all four at 1200×600 minimum. All four get cropped to similar square-ish crops in the grid.
GIF or video cover — 1280×720px
For GIFs and video attachments, use 1280×720px (16:9). Twitter supports up to 15MB for GIFs on mobile and 5MB on web.
Compress before uploading
Twitter recompresses images on upload. Upload JPG at 85% quality or PNG for graphics with text. Target under 1MB per image for fast uploads.
100% Private — Zero Uploads

Pro tip
Pre-optimizing images before uploading to a platform gives you more control than relying on the platform's automatic (and often aggressive) compression.
