Twitter Card Generator
Generate Twitter Card meta tags and preview exactly how your content looks when shared on Twitter/X.
What is Twitter Card Generator?
Twitter Cards are meta tags that control how your website's content appears when shared on Twitter/X. Without Twitter Cards, a shared URL shows only as a plain link. With them, shared URLs display rich previews — an image, title, and description that take up significantly more space in the feed and generate dramatically higher engagement. There are four Twitter Card types: Summary (small image left-aligned with text), Summary with Large Image (prominent full-width image with title and description below), App (for mobile app promotion, showing app store links), and Player (for embedded video/audio). The Summary with Large Image card is the most common for websites and blog posts — it mimics how Open Graph previews look on Facebook, but requires twitter: prefixed tags rather than og: tags (though Twitter falls back to og: tags if twitter: tags are absent). This generator creates all required twitter: meta tags with a live preview of how they'll appear.

Use Cases
Content Marketing
Blog posts, articles, and content pages shared on Twitter perform significantly better with large image cards. The card image acts as a visual headline — choose an image that communicates the post's topic clearly at thumbnail size and includes the human face or key visual that drives engagement on Twitter.
Product and Landing Page Promotion
When sharing product launches or landing pages, a well-crafted Twitter Card is the first impression for users clicking through from a tweet. The title serves as an ad headline and the description as ad copy — treat them with the same care as paid ad creative.
Personal Branding
Professionals and creators sharing their content on Twitter benefit from consistent, branded card appearances. Setting twitter:creator links the card to your Twitter account, building follower attribution for viral content shares.
Features

Real-time preview of your Twitter Card as it will appear in the Twitter/X feed — showing both the desktop and mobile display, including image crop behaviour.
All Card Types

Open Graph Comparison
Shows the equivalent og: tags alongside twitter: tags — clarifying which tags are Twitter-specific and which overlap with Open Graph (Twitter falls back to og: when twitter: are absent).
Frequently Asked Questions
You should have both. Open Graph tags (og:) are used by Facebook, LinkedIn, WhatsApp, and Slack. Twitter Card tags (twitter:) are Twitter-specific. However, Twitter falls back to og: tags if twitter: tags are absent — so if you already have comprehensive og: tags, your Twitter shares will work. The reason to add explicit twitter: tags is control: you can specify a different title or image specifically optimised for Twitter's display format, and the twitter:card type tag (which has no og: equivalent) is required to get summary_large_image cards rather than the default small summary card.
The most common causes: (1) Twitter's crawler hasn't visited your page yet — share the URL in Twitter's Card Validator (cards-dev.twitter.com/validator) to force a re-scrape; (2) Your image URL is blocked by a firewall or requires authentication — Twitter's crawler must be able to fetch the image publicly; (3) The image is too small — Twitter requires minimum 300×157 pixels for summary cards and 300×157 for large image; (4) Your server returns a non-200 status for the URL. Check the Card Validator for specific error messages.
For summary_large_image cards (the most common type): 1200×628 pixels minimum, 1200×600 recommended for optimal display. The aspect ratio is approximately 2:1. Maximum file size 5MB. Twitter crops the image to a 2:1 ratio in most feed contexts. For summary cards (small image): 144×144 minimum, displayed as a square thumbnail. PNG or JPG format. Use a high-contrast image that communicates clearly at small sizes — text in images often becomes unreadable at thumbnail scale.
twitter:site is the Twitter handle of the website or publication — e.g. @yourbrand. twitter:creator is the Twitter handle of the individual author of the specific content — e.g. @authorhandle. For a publication with multiple authors, twitter:site would be the publication's handle and twitter:creator would vary per article based on the author. For solo creators and personal sites, both can be the same handle. Including these tags attributes the content to the correct accounts in Twitter's content graph and may improve tweet attribution when content is reshared.
