This cheat sheet will provide a quick reference to the current LinkedIn guidelines (as of December 2019).
Character counts on LinkedIn include letters, numbers, spaces, punctuation, and symbols (including emojis).

About section preview:
Depending on the device being used (desktop vs. mobile), LinkedIn will show the first couple lines of the About section (and then a prompt to “See More”). On desktop, the preview is approximately 25-40 words (or 270-320 characters). On mobile, viewers see approximately 20-25 characters and then “See More.”

30-character limit (5-character minimum)
