In POSTOPLAN, there is no character limit. But always remember that each social media site has its own limit on the number of characters.
For example, the Instagram caption limit is only 2,200 characters (including spaces). On Facebook and Twitter, the maximum character count is less: 2,000 and 280, respectively.
The character limit for each social platform can be viewed in the field under the post text section.
To do this, select all the social media where you plan to post and click on Text Length button under the Description field.
After that, a window will open where you can find the character limit. The number of characters will change as you enter text.
