Open PixlFits Resizer →X (Twitter) Post Image Size
The best X (Twitter) post image size is 1600 × 900 pixels (16:9). This displays edge-to-edge in the timeline without cropping. X also supports 4:5 portrait and 1:1 square images — but they get cropped to a 2:1 preview in the timeline, so design with the centre in mind.
X (Twitter) Header Banner Size
The Twitter profile header is 1500 × 500 pixels (3:1 ratio). X crops it differently on desktop vs mobile — keep your logo and key content in the centre 60% of the banner width to ensure it's always visible.
