Frequently asked questions
What size is a Twitter/X link preview image?
1200×675 pixels (16:9) for summary_large_image cards. Anything larger is center-cropped, so keep key content inside that frame.

In-feed photos at 16:9 occupy the full card width without cropping. Very tall images get cropped in the timeline, hiding parts of the visual.
How do I control which image shows in a link card?
Set the og:image meta tag on the linked page to a 1200×675 image and X's crawler will pick it up when the link is first shared.
