What is a Twitter Card?

Twitter Cards are rich media previews that appear when someone shares a link on X (Twitter). They include a title, description, and image, making shared links more engaging. The most common type is summary_large_image, which shows a full-width image above the text.

What's the difference between summary and summary_large_image?

summary shows a small square thumbnail to the left of the text (like a news article). summary_large_image shows a large, full-width image above the text — this is the most visually impactful format and what most sites use today.

What Twitter Card meta tags do I need?

At minimum: twitter:card (set to summary or summary_large_image), twitter:title, twitter:description, and twitter:image. You can also add twitter:site for your @username and twitter:creator for the author's @username.

What image size should I use for Twitter Cards?

For summary_large_image: 1200×628px minimum, aspect ratio 2:1, under 5MB. For summary: 144×144px minimum, under 5MB. Twitter supports JPG, PNG, WebP, and GIF (not animated).

Is this Twitter Card validator free?

Yes, completely free. No sign-up, no API keys, no limits on URL checks.

Twitter falls back to og:title, og:description, and og:image when twitter:* tags are absent — the tool shows both sets so you can see exactly what gets used.

Frequently Asked Questions

What Twitter Card types are supported?

This tool shows the summary_large_image layout (the most common and impactful format). It also detects whether the page uses summary, summary_large_image, app, or player card types.

Why is my image not showing?

Twitter requires images to be at least 144×144px, under 5MB, and in JPG, PNG, WebP, or GIF format. The image must use an absolute URL (not relative). Also check that your server allows Twitter's crawler (Twitterbot) to access the image.

Does Twitter fall back to Open Graph tags?

Yes! If twitter:title, twitter:description, or twitter:image are missing, Twitter uses og:title, og:description, and og:image instead. This tool shows both sets so you know what Twitter will actually display.

How do I validate Twitter Cards after publishing?

Use Twitter's official Card Validator at cards-dev.twitter.com/validator after your page is live and publicly accessible. This tool is for pre-publication preview and tag auditing.

Is this tool free?

Yes, completely free. No sign-up, no limits.
