LinkedIn character limits in 2026
LinkedIn enforces different limits for each field. A regular post accepts up to 3,000 characters; the profile headline, 220; the About section, 2,600; a comment, 1,250. Beyond those hard limits there is a practical one: the part of the post visible in the feed before 'see more', roughly 210 characters on desktop and 140 on mobile. That stretch decides whether anyone reads the rest.
This tool applies the limit of the field you choose and shows, in real time, how many characters remain or exceed it. It also counts the hook (the first paragraph) separately so you can check that the visible part fits the available space.
What else the counter analyzes
Besides total characters, you see the count without spaces, words, lines, paragraphs, hashtags and mentions. Reading time is estimated at 200 words per minute, the average on-screen reading speed. Warnings appear when the text exceeds the limit, when the hook passes 210 characters, when there are more than five hashtags or when a paragraph becomes too long to read comfortably on a phone.
Nothing is sent to a server: the analysis runs in your browser. You can paste sensitive texts, client drafts or scheduled posts without worry.
Tips to use the limit to your advantage
Filling all 3,000 characters is rarely the best strategy. Posts between 900 and 1,500 characters usually balance depth and reading time; short posts (under 400) work when there is one idea and a strong hook. In the headline, use the 220 characters to say what you do and for whom, not just the job title. In the About section the first three lines show before 'see more', so start with the most important sentence.
- Keep the hook under 210 characters and end it with a line break.
- Use 3 to 5 hashtags, at the end of the post, relevant to the topic.
- Break paragraphs every 2 or 3 lines for mobile reading.
- Prefer short words: reading time under 1 minute retains more people.
- In comments, 1,250 characters fit a full argument; use them to start conversations.
Frequently asked questions
What is the character limit for a LinkedIn post?
3,000 characters, including spaces, line breaks, hashtags and emojis. Articles have a much larger limit (about 125,000), and the caption of documents and carousels follows the same 3,000 limit.
What is the LinkedIn headline limit?
220 characters. The headline appears under your name everywhere (feed, comments, search), so use the space to say what you do and for whom.
How many characters does the About section allow?
2,600 characters. Only the first three lines show without clicking 'see more', so put the essentials first.
How many characters fit in a comment?
1,250 characters. Long, relevant comments often get big reach because they appear in your contacts' feeds.
How many hashtags should I use?
Between 3 and 5, relevant and at the end of the post. More than that can look like spam and does not improve distribution. See our hashtag guide for details.
Do spaces and line breaks count?
Yes. Every space and every line break counts as one character. Emojis may count as two or more, so keep a margin if you use many.
