Recommended Image and Video Posting Sizes and Restrictions

When posting attachments to any social media platforms via their API (how third-party platforms like Sendible integrate to social sites) you’ll find that there’s restrictions in place which will cause your posts to bounce if you exceed these requirements.

This is not the case when logging in and posting directly to your social media accounts, however, all social media platforms apply restrictions for users posting via their API, and these restrictions differ from channel to channel.

This article will outline all the restrictions and you can jump to the social site you need by clicking on the social site on the right of this article.
