What are Twitter Cards?

Twitter Cards are meta tags that allow web pages to attach rich media experiences to tweets. When users share a URL on X, Twitter reads these tags to display a formatted card with image, title, and description.

What is the difference between summary and summary_large_image?

'Summary' shows a small thumbnail image on the left with text. 'summary_large_image' shows a full-width image above the title and description — more visually engaging and recommended for blog posts and articles.

Can I use Open Graph tags instead of Twitter Card tags?

Yes. If Twitter Card tags are missing, Twitter falls back to reading Open Graph tags (og:title, og:description, og:image). However, explicit Twitter Card tags give you more control over the Twitter-specific appearance.

What image size does Twitter Card use?

For summary_large_image, the recommended size is 1200×628 pixels (2:1 ratio). The minimum is 300×157. For summary cards, images should be at least 144×144 pixels.

How do I test my Twitter Card?

Use this tool for a quick check, or use Twitter's own Card Validator at cards-dev.twitter.com/validator. Note that Twitter requires your site not to be blocked or have restricted access for the validator to work.

What is Twitter Card Checker?

The Twitter Card Checker validates all Twitter Card meta tags on any webpage. Twitter Cards control how your content appears when shared on X (Twitter) — the card type (summary, summary_large_image, app, player), title, description, and image displayed in tweet previews.

With Twitter Card tags properly configured, links shared on X display as rich media cards rather than plain text URLs. Summary Large Image cards show a full-width image with title and description, dramatically increasing engagement compared to plain-text links.

Why Use Twitter Card Checker?

X (Twitter) is a major traffic referral source. Without properly configured Twitter Card tags, your shared links appear as plain text with no image — a stark contrast to competitor content that fills the timeline with compelling imagery. Properly configured cards can double or triple click-through rates from Twitter shares.
