Character Limits in Social Messages

When creating or editing a social message in CoSchedule the character count will be displayed in the lower right corner of the social composer screen. Character limits vary by social network and a warning will be displayed if you've added text that goes over the limit. If you've gone over the limit, CoSchedule will attempt to shorten the text and publish the text so that it is within the character limit — but we recommend keeping the text within the limits listed below.
