Twitter Card Generator

What this tool does

Twitter Card Generator writes the twitter: meta tags that control how links appear in posts on X. Pick a card type, add the title, description, image and accounts, and the tool validates handles and lengths and can omit tags already covered by your Open Graph markup.

X decides how a shared link looks from the twitter:card tag in the page head. Without it, a link may appear as plain text with no image, even if the page has Open Graph tags. Getting the card right matters for anyone who promotes articles, products or videos on X, because a large image card takes up far more of the timeline than a bare URL.

This generator supports the four card types X documents: summary, summary_large_image, player and app. It validates @handles, checks the title against 70 characters, the description against 200 and alt text against 420, and can skip tags that X would read from Open Graph anyway, keeping your head lean. Toolew is not affiliated with X; the preview is an approximation of the current layout.

How to use Twitter Card Generator

1. Choose the Card type; Summary with large image suits most articles and products.
2. Enter the Site account and Author account handles, including the @.
3. Fill in Title, Description, Image URL and Image alt text.
4. For Player or App cards, complete the extra fields that appear.
5. Turn on “Omit tags that Open Graph already covers” if your page already has og: tags, then copy the result.

Tips for better results

• For summary_large_image use an image of at least 300 × 157 px; 1200 × 628 px is a safe choice that also suits Open Graph.
• Images must be under 5 MB and in JPG, PNG, WEBP or GIF format (only the first frame of a GIF is used).
• Always write alt text so people using screen readers know what the card image shows.
• Check the card by pasting the URL into the post composer; X removed the standalone Card Validator preview in 2022.

Common use cases

• Adding large image cards to a blog so posts stand out on X.
• Embedding a video player card for a hosted video or podcast page.
• Keeping one set of tags that serves both X and Open Graph consumers.
• Checking that a page credits the right author account.

Common mistakes to avoid

• Leaving out twitter:card while relying on Open Graph; X needs the card type to show a rich preview.
• Using a player card with an HTTP or non-embeddable URL; player iframes must be served over HTTPS.
• Putting the image behind a login, cookie wall or robots.txt rule that blocks X’s crawler.
• Forgetting that X caches cards; changes can take a while to show on links already shared.
