LinkedIn enforces strict character limits on every field — posts top out at 3,000 characters, headlines at 220, and connection requests at just 300. Going over means LinkedIn silently rejects your content. This free LinkedIn character counter tracks all six key fields in real time, shows a colour-coded progress bar for each, and flags exactly how many characters you are over or under before you hit publish.
LinkedIn allows up to 3,000 characters per post. However, both mobile and desktop apps truncate the visible text much earlier — around 210 characters on mobile and roughly 280 on desktop — before showing a 'See more' button. Pack your strongest hook into the first 200 characters to maximise engagement before the fold.
Your LinkedIn headline can be up to 220 characters. Keep in mind that search results and connection cards only display approximately the first 120 characters, so lead with your most important keywords and value proposition.
The About (Summary) section supports up to 2,600 characters. LinkedIn collapses the section after roughly 300 characters on profile views, so open with a compelling first sentence to entice visitors to expand the full text.
Yes — personalised connection request notes are limited to 300 characters. This is a tight window, so be specific about why you want to connect and skip generic openers. Our counter turns red when you exceed this limit so you can trim before sending.
