Roughly how your card appears when the link is shared. Real platforms re-crop and re-cache, so treat this as a guide.

An X (Twitter) Card turns a plain link into a rich preview with a title, description and image when your page is shared. Those previews come from a handful of meta tags in your page head. This generator writes both the twitter: tags and the matching Open Graph tags, so a single paste makes your link look right on X and every other platform that reads social metadata.
A Twitter Card, now branded an X Card, is the preview block that X builds when it sees your URL. X reads tags such as <meta name="twitter:card">, <meta name="twitter:title">, <meta name="twitter:description"> and <meta name="twitter:image"> from the <head> of your page, then renders a card in the timeline. The twitter:site tag attributes the card to your @handle. Open Graph tags like <meta property="og:title"> and <meta property="og:image"> do the same job for Facebook, LinkedIn, Slack and Discord, and X uses them as a fallback when a twitter: tag is absent. That is why a complete setup ships both sets together, which is exactly what the tool above produces.
The twitter:card value decides the layout. summary_large_image renders a full-width banner above the title and description and is the right pick for articles, product pages and landing pages, because the larger image earns more clicks in a busy feed. It expects a 2:1 image, at least 300x157 pixels, with 1200x628 recommended. summary shows a small square thumbnail to the left of the text and suits posts where you only have a logo or icon. It expects a square image, at least 144x144 pixels, with 240x240 or larger recommended. Keep images under 5 MB, host them on an absolute HTTPS URL, and avoid tiny text inside the image since it gets downscaled on mobile.
Copy the generated block and paste it inside the <head> of your page, ideally near your title tag, then deploy so the tags are live. Each card needs an absolute, public, HTTPS image URL: relative paths and pages blocked in robots.txt will not render. After deploying, run the page through the official X Card validator and a general Open Graph debugger such as the one from Facebook or a free OG preview tool. These crawlers fetch your live page and show the exact card, and they reveal missing tags or images that fail to load. If you update an image, the platforms cache the old one, so re-run the validator to force a fresh fetch. Once the preview looks correct there, it will look the same to everyone who shares the link.
