LinkedIn character limits
Post: 3,000 characters. Comment: 1,250. Headline: 220. About section: 2,600. Connection note: 200 on a free account and 300 on Premium. Those are the ones you hit every week.
Tip: Spaces and line breaks count too. A post with a blank line after every sentence uses up its 3,000 characters, and its three visible lines, faster than you think.
Where “…more” cuts your post
LinkedIn shows about 210 characters on desktop and about 140 on a phone before it hides the rest behind “…more”. It also stops after three lines, and blank lines count. So a post that opens with one word, a blank line and another word shows almost nothing.
Your job is to fit the hook inside that space. Score it with the LinkedIn hook checker, and if you need a whole post from an idea, start with the LinkedIn post generator.
Long post or short post
There’s no magic length. A sharp two-line post can do better than a 2,500-character essay. What matters is that every line earns the next one. If the reading time says two minutes, ask yourself whether you’d read two minutes of it from a stranger. Be honest.
Too long? Cut it with the LinkedIn readability checker. Ready to post? Add bold and lists in the LinkedIn post formatter. Writing a headline? The LinkedIn headline generator keeps every option under 220.
