How Twitter Cards Work

Twitter Cards use meta tags in your HTML to display rich media experiences when your content is shared on Twitter. When someone shares a link to your content, Twitter displays a "card" that includes additional information beyond just the URL.

Common Issues & Solutions

  • Ensure your card meta tags are in the <head> section of your HTML.
  • The twitter:card meta tag is required and must have a valid value.
  • Include required meta tags for your card type (twitter:title, twitter:description, etc.).
  • Image dimensions may be too small - minimum 144x144px for summary cards.
  • Twitter may be caching an older version - use the URL with a query parameter to force refresh.

  • Ensure your image URL is absolute, not relative.
  • Check image dimensions:
    • Summary Card: Minimum 144x144px, 1:1 aspect ratio recommended
    • Summary Large Image: Minimum 300x157px, 2:1 aspect ratio recommended
  • Maximum file size is 5MB.
  • Supported formats: JPG, PNG, WEBP, GIF (static only).
  • Ensure your server allows Twitter's crawler to access your images.

  • Twitter may be caching old metadata. Add a cache-busting parameter to your URL (e.g., ?v=1).
  • Check for conflicting Open Graph (og:) tags, which Twitter may use as fallbacks.
  • Ensure your twitter:title and twitter:description are properly defined.
  • Twitter truncates titles at approximately 70 characters and descriptions at around 200 characters.
