Twitter (X) card types: summary vs summary_large_image
| twitter:card | Looks like |
|---|---|
| summary | Small square thumbnail beside the text |
| summary_large_image | Full-width image above the text. Best for most content. |
| player | Embedded video or audio player (needs approval/whitelisting) |
| app | App install card |
Fallbacks
If twitter:title, twitter:description or twitter:image are missing, X uses og:title, og:description and og:image. The one tag you should always set is twitter:card.
<meta name="twitter:card" content="summary_large_image"> <meta name="twitter:site" content="@yourbrand">
Testing
X removed the preview from its Card Validator in 2022. To test, paste the URL into a new post (you don't need to publish it), or use the previewer. X has changed how much text large cards show several times; recent versions show the image with the domain overlaid, so put the key message in the image itself.
