LinkedIn Character Limits Explained
Post Character Limit: 3,000
LinkedIn posts can contain up to 3,000 characters, but only about 140 characters are visible before the "...see more" link. Your opening hook is critical for driving engagement. Posts between 1,200-1,500 characters tend to perform best for engagement.
Article Character Limit: 125,000
LinkedIn articles (published through the native article feature) can be up to 125,000 characters—roughly 20,000 words. However, articles between 1,900-2,000 words get the most engagement and shares.
Headline Character Limit: 220
Your headline appears below your name everywhere on LinkedIn. It's searchable and crucial for personal branding. Use keywords relevant to your industry and clearly state your value proposition.
About Section: 2,600 Characters
The About section (formerly Summary) gives you space to tell your professional story. Include keywords, achievements, and a call-to-action. Only the first 265-275 characters show before "see more."
Comment Character Limit: 1,250
LinkedIn comments allow up to 1,250 characters. Thoughtful, longer comments can boost your visibility in the algorithm and help you build relationships with content creators.

Tips for High-Performing LinkedIn Posts
1. Hook in the First Line
With only ~140 characters visible before "see more," your opening line must stop the scroll. Start with a bold statement, surprising statistic, or thought-provoking question.
2. Use Line Breaks Generously
LinkedIn's algorithm and readers favor posts with white space. Use single-sentence paragraphs and line breaks between ideas. This dramatically improves readability and engagement.
3. Tell Stories
Personal stories and case studies outperform generic advice. Share your experiences, failures, and lessons learned. Authenticity builds trust and drives comments.
4. End with a Question or CTA
Prompt engagement by ending with a question that invites responses. Comments significantly boost your post's reach in the LinkedIn algorithm.
5. Post Timing Matters
Tuesday through Thursday mornings (7-8am) tend to see higher engagement. Experiment with timing based on when your specific audience is most active.
6. Engage with Comments
Respond to comments within the first hour to boost algorithmic reach. Ask follow-up questions to keep conversations going.
