What counts toward the LinkedIn limit
LinkedIn Help puts the post limit at 3,000 characters, and Pages use the same composer, so the number is the same whether you post as yourself or as a company. Spaces, line breaks, emoji, hashtags and links all count.
The limit you notice first is the fold. The feed shows only the start of a post before “see more”, so the first line or two decide whether anyone reads on. For writing longer than 3,000 characters, LinkedIn points you to articles.
Other fields have their own limits: comments take up to 1,250 characters, poll questions 140 and each poll option 30. The headline (220), Page tagline (120) and article title (150) figures come from secondary sources rather than LinkedIn Help.

Hashtags on LinkedIn
Hashtags can go in post text. The LinkedIn help pages we reviewed publish no hashtag limit. Stick to a few specific tags.
Tips for LinkedIn posts
- Write the first line as a complete thought that makes people want the rest.
- Use short paragraphs with blank lines between them. Long blocks of text are hard to read on a phone.
- Turn a slide deck into a document post to make a swipeable carousel.
- Ask a question or run a poll to start a discussion, keeping each option within 30 characters.
- Add alt text to every image. LinkedIn recommends keeping it under 120 characters, though the API accepts up to 4,086.
Publish LinkedIn posts that fit, on schedule
Postocial publishes to LinkedIn profiles and LinkedIn Pages. Write a fuller LinkedIn version of a post next to shorter versions for other networks, add a first comment or post a document carousel, then drop it into the next free slot in your queue.
On Premium and higher plans, comments on your LinkedIn Page posts come into the unified inbox with your other channels. See how Postocial works with LinkedIn.
