LinkedIn Character Limits

Every limit is taken from the platform’s own help or developer pages, last checked on 4 October 2026. Platforms change these without notice, so if a figure looks wrong, the linked page is the one to trust.

LinkedIn gives you two places to publish. A post is the short update that appears in the feed, and it stops at 3,000 characters. An article is a longer piece with its own page and headline, and it can run to 125,000 characters, which is roughly 20,000 words of English.

The tightest limit is the note on a connection request: 200 characters on a free account, or 300 with Premium. That is about two sentences, so it is worth drafting the note first and checking it here before you send.

LinkedIn’s Help Center does not currently publish a limit for the profile headline or the About section, so we do not list one. The figures you see on other sites are not from LinkedIn. When you edit either field, LinkedIn’s own form tells you if you have gone over, so treat that as the final word.

A connection note that fits the free 200-character limit with room to spare:

Hi Sam, I enjoyed your talk on hiring for small teams at the Lagos meetup. I run recruiting at a 12-person startup and would love to stay in touch.

That is 147 characters including spaces. A post of 3,000 characters is around 450 to 500 words, about the length of a short blog post. If your draft is longer than that, publish it as an article instead.

• SMS
• UCAS personal statement

For anything else, the character counter counts with and without spaces.
