The character limit for a LinkedIn headline is 220 characters. A headline is the short line displayed beneath a member’s name, and it is designed to summarize professional identity, expertise, or career focus.
LinkedIn increased the headline limit from 120 to 220 characters, giving members more room to describe what they do and whom they help. The limit applies to the headline field, not to the About section, job descriptions, posts, or connection messages.
A common mix-up is confusing the headline with LinkedIn’s post limit or with older profile guidance written when the limit was shorter. Because the headline appears in search results, comments, and profile previews, the most useful 220-character versions usually lead with a clear role or specialty rather than a vague slogan.
