Custom Social Media Previews

What is a social media preview card?

Social media previews (referred to on Twitter as Twitter cards), are the little previews of websites you see when you share a link.

These previews come from open graph meta tags that are embedded in the destination page.

Linkly allows you to override these previews with your own title, image and description.

Testing Social Media Previews

Note: X (formerly Twitter) has deprecated their Card Validator tool. To test X previews, post your link in a draft tweet or use the Facebook Sharing Debugger as a general indicator.

What image sizes should I use for social media images?

  • Standard Size: 1200 × 630 px (recommended by Facebook and used widely)

  • Aspect Ratio: 1.91:1
  • Max File Size: ≤ 5MB (JPEG or PNG preferred)

Automatic optimization: Linkly automatically resizes and optimizes your images to 1200 × 630 px for optimal social media display. You can upload larger images and Linkly will handle the rest.

Platform-specific notes:

  • Facebook: Uses 1200 × 630 px for best display in shared posts
  • X (via twitter:image): Recommend 1200 × 675 px (16:9 ratio); will fall back to OG tags
  • LinkedIn: Also favors 1200 × 627 px
