What is the difference between summary and summary_large_image?

The layout of the card. A summary card shows a small square thumbnail beside the title and description; a summary_large_image card shows a wide image above them. The generator labels them Summary and Summary with large image and starts on the large one. Switching changes only the twitter:card line, so pick summary when your image is a square logo and summary_large_image for a wide photo or banner.

What do twitter:site and twitter:creator hold?

An @username: the site field for the website’s account, the creator field for the author’s. Type either with or without the @; example is written @example. 1 to 15 letters, digits or underscores are accepted, so @jane.doe is refused.

Why is my card image URL refused?

The image must be a full address that starts with http:// or https://, with no spaces, backslashes or user:password@. /card.jpg gets "The image URL must be a full address starting with http:// or https://."

Can I make an app card or a player card?

No. App and player cards need further tags that this generator does not write, so only summary and summary_large_image are offered.

How long can the card title and description be?

The figures commonly cited are 70 characters for the title and 200 for the description; this tool takes them from Elementor’s card generator, as X’s own documentation could not be checked. A 71-character title gets "The title is 71 characters, over 70. It may be cut off on the card." The counters under the fields change to the error color past the limit, but the tags are still written in full, up to 1,000 characters.

About the Twitter Card Generator

With every field empty the Twitter card generator writes one tag, <meta name="twitter:card" content="summary_large_image" />, and asks for a title, description or image. It offers the summary and summary_large_image cards, writes each @handle with one @, and accepts only full http:// or https:// image addresses. App and player cards need tags it does not write.

Fields and tags, in output order

Field	Tag
Card Type	twitter:card
Site (@username)	twitter:site
Creator (@username)	twitter:creator
Title	twitter:title
Description	twitter:description
Image URL	twitter:image
Image description	twitter:image:alt

twitter:card is always written. The others appear when the field holds a valid value; an image description needs a valid image URL.

Handles

You type	Written as

Card tags and Open Graph

Use it when a page shared on X should show a card with its own title, description and image, with the site's and the author's @handles attached. This tool writes only the twitter: tags; the Open Graph Generator writes the og: tags other apps read.

The card preview above the tags is a sample layout: a wide frame for the large-image card, a square one for summary, then the site handle, title and description. Your image URL is not loaded, so the frame stays empty.

Tag order and checks

twitter:card always comes first, with summary or summary_large_image. The other fields follow in this order when they are filled in: twitter:site, twitter:creator, twitter:title, twitter:description, twitter:image, twitter:image:alt. A handle is 1 to 15 letters, digits or underscores and is written with one @, whether you type the @ or not. The image must be a full http or https address.

Example: card type Summary, site example, creator @jane_doe, title Blue Widgets and image https://example.com/card.jpg give:

<meta name="twitter:card" content="summary" />
<meta name="twitter:site" content="@example" />
<meta name="twitter:creator" content="@jane_doe" />
<meta name="twitter:title" content="Blue Widgets" />
<meta name="twitter:image" content="https://example.com/card.jpg" />

with a reminder to add an image description. A title over 70 characters or a description over 200 gets a warning that it may be cut off, and the counters under the fields change to the error color. These are commonly cited display limits, taken from Elementor's card generator rather than X's own documentation, so the tags are still written in full. App and player cards need tags this tool does not write, so they are not offered.
