X (Twitter) Post Image Size
For a single image in an X (Twitter) post, upload 1600×900 px (16:9) — it fills the most width in the timeline without cropping. Square 1080×1080 (1:1) also displays in full. Minimum is 600×335; anything smaller looks soft.

1600×900 | 16:9 | |

600×335 | 16:9 |
1600×900 for a single image
A single image in an X post shows widest at 16:9 (1600×900 px). X keeps that ratio uncropped in the timeline, so it's the safest choice for screenshots, quote cards and photos.
Square also works
1:1 (1080×1080) displays in full too and takes more vertical space, which can stop the scroll. Portrait 4:5 is accepted but may be cropped in the timeline preview until tapped.
Multi-image layouts
Two, three or four images are auto-arranged into a grid and each thumbnail is cropped to fit. For predictable crops in a 2-up or 4-up grid, use square 1:1 images.
