LinkedIn Character Counter — Post, Headline & Bio Length Checker
LinkedIn Character Counter — Complete Guide 2026
Our LinkedIn character counter helps professionals optimize every field of their profile and content. LinkedIn feed posts support up to 3,000 characters, but the feed displays only the first 210 characters before truncating with a "see more" link.
The LinkedIn headline supports up to 220 characters and is the most searchable field on your profile. Use our character count limit tracker to maximize keyword density without exceeding the boundary.
About Section Optimization
The About (Summary) section allows up to 2,600 characters. This is your prime real estate for SEO — include industry keywords, achievements, and a clear value proposition. Our counter tracks this limit in real time so you can write confidently.
Tips for LinkedIn Posts
- Start with a hook in the first 210 characters — that's all people see before 'see more'
- Use line breaks generously — white space increases readability and dwell time
- Add 3–5 relevant hashtags at the end of posts (not scattered throughout)
- Keep connection request notes under 300 chars and always personalize them
- Test different post lengths — data shows 1,200–1,800 chars often performs best

Frequently Asked Questions
What is the LinkedIn post character limit in 2026?
LinkedIn feed posts are limited to 3,000 characters including spaces, emojis, and hashtags. Only the first 210 characters are shown in the feed before the 'see more' link appears. Our LinkedIn character counter shows both the total count and the preview threshold simultaneously.
How long can a LinkedIn headline be?
LinkedIn headlines can be up to 220 characters long. This field appears in search results, connection requests, and the top of your profile. Use this space for role-specific keywords rather than just your job title.
What is the LinkedIn connection request message limit?
LinkedIn connection request notes are limited to 300 characters. This is a strict character count limit — exceeding it will prevent you from sending the invitation. Keep messages concise, personalized, and action-oriented.
What is the LinkedIn About section character limit?
The LinkedIn About section (formerly Summary) allows up to 2,600 characters. Unlike posts, there is no truncation in the profile view, but only the first ~300 characters show in search snippets. Front-load your most important keywords.
How many characters can a LinkedIn comment have?
LinkedIn comments are limited to 1,250 characters. For longer responses, consider writing a separate post and tagging the original author instead.
Does LinkedIn count characters or words?
LinkedIn uses character count, not word count, for all limits. This includes letters, numbers, spaces, punctuation, and emojis. Our tool provides a real-time character length check so you never exceed platform boundaries.
What is the LinkedIn article character limit?
LinkedIn articles (long-form posts) support up to 125,000 characters, making them ideal for thought leadership content. However, titles are limited to 100 characters and descriptions to 200 characters for SEO purposes.
