One of my LinkedIn coaching clients has a great story to tell. She needs to explain a gap in her career.
Unfortunately she ran out of the space allotted on her LinkedIn summary section to tell that story.

Linkedin limits the characters (including spaces) in each section. You knew that.

As an aid to all of you (myself included) a friend did the research and came up with the attached document that shows the LinkedIn sections and their character limitations. I hope this helps you.
