About the X (Twitter) in-stream image size
A single image posted to X looks best at 1600 by 900 pixels, a clean 16:9. The timeline shows a cropped preview that leans toward 16:9, and viewers tap to see the whole thing, so a landscape image that already matches that ratio avoids an unflattering auto-crop. If you post an infographic or anything tall, expect the preview to clip the top and bottom until it is opened. Keep files reasonable; X recompresses large uploads.
