LinkedIn Character Limits: Complete Reference
LinkedIn Post Character Limit (3,000)
LinkedIn posts allow up to 3,000 characters including spaces, emojis, and special characters. However, LinkedIn truncates posts after approximately 210 characters in the feed, showing a “See more” link. This means your opening hook needs to grab attention within those first few lines. Posts that drive the most engagement typically use 1,200 to 1,800 characters, long enough to deliver value, short enough to stay focused. Want to schedule your LinkedIn posts directly from Notion?

LinkedIn Article Character Limit (125,000)
LinkedIn articles (published via the article editor, not regular posts) allow up to 125,000 characters. Articles support rich formatting, images, and embedded media. They're indexed by search engines and live permanently on your profile, making them ideal for long-form thought leadership content.
LinkedIn Headline Character Limit (220)
Your LinkedIn headline is limited to 220 characters and appears everywhere your profile is visible: search results, connection requests, comments, and shared posts. A well-crafted headline clearly communicates who you are and what value you bring. See how LinkedIn creators use Scheduled to optimize their profiles and content.
LinkedIn Message Character Limit (8,000)
Direct messages on LinkedIn allow up to 8,000 characters. InMail messages (sent to users outside your network) are more limited: 200 characters for the subject line and 1,900 for the body. Keep cold outreach concise. Shorter messages consistently get higher response rates.
LinkedIn Comment Character Limit (1,250)
LinkedIn comments are limited to 1,250 characters. Commenting is one of the best ways to grow on the platform. Thoughtful, long comments on popular posts can drive significant profile views and new connections.
LinkedIn Company Update Limit (700)
Company page updates (posts from a LinkedIn company page) are limited to 700 characters. This tighter limit forces brands to be concise. Focus on a clear message and a strong call-to-action.

Frequently Asked Questions
LinkedIn posts have a maximum character limit of 3,000 characters. This includes spaces, emojis, and special characters. However, only the first ~210 characters are visible before LinkedIn shows a "See more" link, so make your opening hook count.
