Notes

A. Post text length

Twitter:

The following items are included in message length and will affect the character limit:

  • New non-reply Tweets starting with a @mention.

  • Any @mentions added in the body of the Tweet.

  • Embedded links and URLs typed within the message body.

The following items are not included in message length and won't affect the character limit:

  • When attaching images or videos to the message, the generated URL.

  • Leading spaces before the first character of a message.

Instagram: Be aware of the following limitations and restrictions for creating Instagram posts

  • The caption cannot contain more than 30 hashtags.

B: Image restrictions

All images must be JPG, PNG, GIF with maximum 5MB file size and 50MP resolution. In addition, be aware of the following channel-specific limitations:

  • Facebook: PNG images larger than 1MB may appear pixelated. The maximum file size is 5MB. Aspect ratio must be from 1:1.91 to 1:0.56.

  • Instagram: Minimum 600px width. Preferred JPEG size is 640x640. Maximum resolution is 1920x1080 and 2,073,600 pixels. Photos must be within a 4:5 to 1.91:1 aspect ratio range.

  • Twitter: Maximum image size for a tweet is 1280x1024; maximum file size is 5MB. Although Twitter allows multiple images, you cannot mix a GIF image (animated or static) with any other image type.

  • LinkedIn: Supports JPEG and PNG file types. The maximum file size is 5MB.

C: Links

Attached Links: Attached links are added through the link icon in the publisher.

  • Facebook: Attached links will appear in a 'card' below the post. At this time, the 'card' can not be edited.

  • Twitter: If Twitter Cards have been enabled for the domain, attached links will appear in a 'card' below the tweet with an image and description. At this time, the 'card' can not be edited. If Twitter Cards have not been enabled, you will receive an error message and the link will need to be embedded.

  • LinkedIn: Attached links will appear in a 'card' below the post. At this time, the 'card' can not be edited.

Embedded Links:

  • Facebook: Links added to the body of a post will be hyperlinked, but will not show the 'card' below the post.

  • Twitter: If Twitter Cards have been enabled for the domain, links that are added to the body of a tweet will appear in a 'card' below the tweet with an image and description. If Twitter Cards have not been enabled, the link will still appear in a 'card' below the tweet, but without an image or description.

  • LinkedIn: Links added to the body of a post will be automatically shortened and hyperlinked, but will not show the 'card' below the post.

Note: link shortening is currently on our roadmap. Stay up to date on our latest releases here.
