X’s own documentation is behind a login and we could not read it. These numbers come from a published guide that describes X’s older documentation, so they can be out of date. The largest image is 4096 × 4096 pixels, and JPG, PNG, WEBP and GIF work.
The guide says X shows the title over the image on a large card. We have not measured where, so keep the bottom of the image free of text.
Add the twitter:card tag with the value summary_large_image to get the large card.
