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.

Frequently Asked Questions

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.
