LinkedIn has different character limits for nearly every text field on the platform. Knowing these limits helps you plan content that fits without awkward truncation. This reference covers every major section as of 2026.
LinkedIn Post Character Limit
Regular LinkedIn posts have a 3,000 character limit (LinkedIn Help). Earlier versions of the platform had a lower limit, so older guides may cite different numbers.
LinkedIn truncates posts with a “...see more” link. The exact cutoff varies by device and is not published by LinkedIn — it is commonly observed at roughly 140-210 characters depending on screen size, with mobile showing less. Use your first 140 characters for a strong hook to cover both cases — consider bolding your opening line to make it stand out.
Note: Unicode formatted characters (bold, italic, etc.) may count differently than plain letters in some contexts. LinkedIn's internal character counter is the authoritative source — watch it as you compose.
Optimal Post Length
Having 3,000 characters does not mean you should use all of them. Many LinkedIn creators find that medium-length posts — long enough to provide substance but short enough to hold attention — often work well. Very short posts (under 300 characters) may lack enough depth to prompt reactions, while very long posts can lose readers before the call-to-action.
The sweet spot depends on your content type: storytelling posts can go longer, tip-based posts work best shorter. Use the Post Preview tool to check how your post looks at different lengths.
LinkedIn Headline
Your headline has a 220 character limit. This is the text that appears directly below your name on your profile, in search results, and on connection requests. It is one of the most visible pieces of text on LinkedIn.
Since the headline is short, every word matters. Many professionals use separators (|, —, or Unicode symbols) to fit multiple pieces of information. You can also use bold Unicode text in your headline to add visual emphasis, though readability should come first.
LinkedIn About Section (Summary)
The About section allows up to 2,600 characters. This is your professional summary — the space where you describe who you are, what you do, and who you help.
Only the first ~300 characters are visible before the “see more” fold on your profile. Structure the About section with line breaks and formatted text (bold headers, bullet points) to make it scannable for visitors who do expand it.
LinkedIn Comments
Comments on LinkedIn posts have a 1,250 character limit. First-level comments and replies share the same limit.
Formatting works in comments — you can use bold, italic, and other Unicode styles. A formatted comment stands out visually in a thread, which may attract more attention to your response.
LinkedIn Articles
LinkedIn articles (the long-form publishing feature) have a 125,000 character limit— roughly 20,000 words. Articles support native rich text formatting (bold, italic, headers, links, images) through LinkedIn's built-in editor, so you do not need Unicode formatting for articles.
Article titles are limited to 100 characters.
LinkedIn Polls
LinkedIn polls have their own character limits:
- •Poll question: 140 characters
- •Each answer option: 30 characters
- •Number of options: up to 4 on desktop and Android, up to 5 on iOS (per LinkedIn Polls FAQ)
- •Accompanying post text: 3,000 characters (same as regular posts)
Poll questions are short, so clarity matters. Avoid questions that require long answer options — 30 characters per option means you need concise wording.
LinkedIn Messages
Direct messages (DMs) and InMail have different limits:
- •Regular messages: 8,000 characters
- •InMail subject line: 200 characters
- •InMail body: 1,900 characters
- •Connection request note: 300 characters
Unicode formatting works in all LinkedIn messages. A bolded key phrase in a cold outreach message can help it stand out in a crowded inbox.

Tips for Working Within Character Limits
- →Use the Post Preview tool to check where your post truncates before publishing
- →Front-load your most important information — the first 140-210 characters (depending on device) determine whether readers expand your post
- →Use formatting (bold, bullet points) to make longer posts scannable rather than cutting content to fit shorter limits
- →LinkedIn's own character counter is the definitive source — third-party counters may count Unicode characters differently
Sources and Notes
Confirmed by LinkedIn Help: Post limit (3,000 characters) — see post updates. Article limit (125,000 characters) — see posts vs articles. InMail subject (200) and body (1,900) — see InMail character limits. Poll question (140) and options (30 each) — see LinkedIn Polls FAQ.
Commonly observed limits:Headline (220), About (2,600), comments (1,250), messages (8,000), connection note (300) are based on widely reported platform behavior. The “see more” truncation point (140-210 characters) is also observed UI behavior, not a LinkedIn-published limit. These values may vary as LinkedIn updates its product. Always verify with LinkedIn's own editor when approaching a limit.
LinkedIn may change any of these limits without notice. This page reflects platform behavior as of 2026.
