Guide

X cards

X cards turn a bare link into a rich preview with an image, title and description. The large-image card takes up much more of the timeline and usually earns more clicks; the summary card shows a small square thumbnail.

If twitter: tags are missing, X falls back to Open Graph tags, so many sites only need twitter:card plus their existing Open Graph tags.

Tips

Tips for using the Twitter card generator

Use the large image card

It takes up more of the timeline and usually earns more clicks.

Keep titles short

X shows about 70 characters of the card title.

Reuse Open Graph

X falls back to Open Graph tags; generate those with the Open Graph generator.

Add image alt text

twitter:image:alt makes your card accessible to screen reader users.

FAQ

Twitter Card Generator FAQ

What image size should I use?

1200×628 pixels for large-image cards; at least 144×144 for summary cards.

How do I refresh a cached card?

X re-fetches cards periodically. Posting the URL with a harmless query string (?v=2) forces a fresh one.

Is anything uploaded?

No. The code is generated in your browser.

Do Twitter cards still work on X?

Yes. X still reads twitter: meta tags to build link previews.

Why isn't my card showing?

Check the tags exist and the image is public. X may cache old versions for a while.

What's the summary card?

A smaller layout with a square thumbnail beside the title.
