What is the difference between summary and summary_large_image?

Summary shows a small square thumbnail (144x144 min) next to the title and description. Summary_large_image shows a full-width banner image (minimum 300x157, recommended 1200x628) above the text.

Do I need both og: and twitter: tags?

Twitter falls back to Open Graph tags if twitter-specific tags are missing. However, having dedicated twitter: tags gives you full control over how the card appears on X versus Facebook/LinkedIn.

How do I validate my Twitter Card?

Use the Twitter Card Validator at cards-dev.twitter.com/validator. Paste your URL and it will show you exactly how the card renders.

What image size should I use?

For summary_large_image, use 1200x628 pixels (1.91:1 ratio). For summary, use at least 144x144 pixels square. Images must be under 5MB.

What does twitter:site vs twitter:creator mean?

twitter:site is the @handle of the website or brand account. twitter:creator is the @handle of the content author. Both are optional but improve attribution.

The short version

What is Twitter Card Generator?

Twitter Cards are special meta tags that control how your links appear when shared on X (formerly Twitter).

Without them, shared links show a plain URL with no image or description. With the right tags, your link unfurls into a rich card with an image, title, description and attribution. This generator supports both the compact summary card and the more prominent summary_large_image card. Fill in the form, check the live preview, and copy the ready-to-use HTML to paste into your page head. Everything runs client-side in your browser.
