Twitter (X) Cards
Twitter Cards are a family of meta tags — prefixed twitter: — that control how a link appears when shared on Twitter/X. They largely mirror Open Graph in purpose, but use their own namespace and card-type system.
Core tags
<meta name="twitter:card" content="summary_large_image" /> <meta name="twitter:title" content="HTML Tutorials for Every Level" /> <meta name="twitter:description" content="Learn HTML from fundamentals to advanced SEO and accessibility." /> <meta name="twitter:image" content="https://letcodes.example/og/html.png" /> <meta name="twitter:site" content="@letcodes" />
Tag | Purpose |
|---|---|
twitter:card | Card layout type — see the two most common values below |
twitter:title | Headline shown on the card |
twitter:description | Short summary text |
twitter:image | Preview image URL |
twitter:site | The site's own @handle (optional) |
twitter:creator | The content author's @handle, if different from the site |
summary vs summary_large_image
Card type | Layout |
|---|---|
summary | Small square-ish thumbnail beside the title/description — good for profile photos or logos |
summary_large_image | Full-width image above the title/description — the standard choice for article and blog previews |
<!-- Compact card, small thumbnail --> <meta name="twitter:card" content="summary" /> <!-- Prominent card, large image banner --> <meta name="twitter:card" content="summary_large_image" />
Falling back to Open Graph
Twitter/X will read equivalent Open Graph tags (og:title, og:description, og:image) when the matching twitter: tag is missing. In practice, many sites only set twitter:card explicitly and rely on Open Graph for everything else, since the two overlap almost completely.
<!-- Minimal setup: only declare the card type, reuse Open Graph for content --> <meta property="og:title" content="HTML Tutorials for Every Level" /> <meta property="og:description" content="Learn HTML from fundamentals to advanced SEO and accessibility." /> <meta property="og:image" content="https://letcodes.example/og/html.png" /> <meta name="twitter:card" content="summary_large_image" />
Always set twitter:card explicitly — without it, X may not render a rich card at all even if Open Graph tags are present.
Image requirements differ slightly from Open Graph (aspect ratio, minimum size) — check current platform documentation before finalizing image dimensions.
Use a dedicated card validator tool to preview and debug rendering before publishing widely.
twitter:card (and optionally twitter:site) is usually enough to get a good-looking card on X with minimal extra work.
