How do I edit what my post looks like on social media?

Interested in seeing what your post will look like on social media?

1. From the Substack post editor, click on Settings next to the Publish button.

2. The social preview displays what your post will look like on social media.

  • To change the text, click the "edit" link, or click on the box itself.
  • To select a different image from your post for the preview, hover over the thumbnail or click "Upload New".


Tip: For photos to appear in the social preview, we recommend the dimensions to be at least 420x300 pixels (or larger).
