LinkedIn Character Limits in 2026: Every Field, Every Limit (Quick Reference)

Every field on LinkedIn has a character limit — and hitting it at the wrong moment means your message gets cut off mid-sentence, your headline loses its punch, or your connection request sounds incomplete. This guide gives you every LinkedIn character limit in one place, plus tips for writing within each constraint.

LinkedIn Character Limits: Quick Reference Table

Here are all current LinkedIn character limits for 2026, in one table:

| Content Type | Character Limit | |---|---| | Post | 3,000 characters | | Post (visible before "See more") | ~210 characters (mobile), ~250 (desktop) | | Headline | 220 characters | | About / Summary | 2,600 characters | | Comment | 1,250 characters | | Connection request (free) | 200 characters | | Connection request (Premium) | 300 characters | | InMail subject line | 200 characters | | InMail body | 1,900 characters | | Company page tagline | 120 characters | | Company page description | 2,000 characters | | Article title | 100 characters | | Article body | No limit | | Newsletter name | 60 characters | | Event name | 75 characters | | Group name | 100 characters |

Bookmark this table. Now let's break down the limits that matter most — and how to write effectively within each one.

LinkedIn Post Character Limit

LinkedIn posts have a 3,000-character limit, which translates to roughly 500 words. That's enough space for a detailed story, a listicle with 10 items, or a step-by-step breakdown of a complex topic. Most high-performing posts fall between 1,200 and 2,500 characters.

But the real constraint isn't the total limit — it's the "See more" cutoff.

The "See More" Cutoff

On mobile, LinkedIn shows only the first ~210 characters of your post before collapsing the rest behind a "See more" link. On desktop, that threshold is slightly higher at around 250 characters. If your opening doesn't earn the click, the rest of your post is invisible.

This means the first two lines of every post function as a headline. They need to create curiosity, state a bold claim, or promise specific value. Generic openings like "I'm excited to share..." or "Happy Monday, everyone!" waste the most important real estate in your entire post.

Strong hooks follow a pattern: tension, specificity, or a surprising number. For example, "I got 47 leads from one LinkedIn post. Here's the exact format I used." That's about 80 characters and it creates enough curiosity to earn the click. For more hook templates and post formats, check out our LinkedIn post ideas guide.

Tips for Staying Within the Post Limit

• Write your post in a character counter so you can see exactly where you stand
• Use line breaks liberally — a wall of text discourages reading even if it's under the limit
• Format your post with Pollen's LinkedIn post formatter to add bold text, bullet points, and clean spacing
• If you consistently need more than 3,000 characters, consider publishing a LinkedIn article instead

LinkedIn Headline Character Limit

Your LinkedIn headline allows 220 characters. On desktop, most of the headline is visible on your profile card. On mobile and in search results, it gets truncated — usually around 60-80 characters show depending on the device.

This means you should front-load your headline with your most important keywords and value proposition. Don't bury the good stuff at the end where mobile users will never see it.

A common mistake is using only your job title ("Marketing Manager at Acme Corp"). That's around 30 characters — you're wasting 190 characters of prime real estate. Instead, stack your headline with keywords your target audience is searching for: what you do, who you help, and the result you deliver.

For inspiration and formulas, see our guide on LinkedIn bio and headline examples. You can also test your headline with Pollen's LinkedIn headline analyzer, which scores your headline on clarity, keyword usage, and overall impact.

LinkedIn About Section Character Limit

The LinkedIn About section (sometimes called the Summary) gives you 2,600 characters — roughly 400-450 words. But only the first ~300 characters are visible above the fold before the "See more" link.

How to Structure Your About Section

Use the Hook-Bridge-Proof-CTA formula:

1. Hook (first 300 characters): Open with a compelling statement about who you help and what problem you solve. This is the only part most visitors will read, so make it count.
2. Bridge: Explain your approach, your background, or your philosophy. Connect the hook to your credibility.
3. Proof: Share specific results, experience, or credentials. Numbers are more persuasive than adjectives.
4. CTA: End with a clear next step — how to contact you, what to do next, or what to expect from your content.

LinkedIn Comment Character Limit

LinkedIn comments have a 1,250-character limit — roughly 200 words. That's substantially more than most people realize, and there's a strategic reason to use it.

LinkedIn's algorithm gives more weight to longer, more substantive comments. A comment that adds genuine insight, shares a personal experience, or asks a thoughtful follow-up question signals higher engagement quality than a simple "Great post!" — both to the algorithm and to the person who wrote the original post.

Longer comments also increase your visibility. When someone writes a detailed comment, other readers are more likely to click through to their profile. It's one of the most underrated LinkedIn growth strategies.

That said, don't pad your comments just to hit a length threshold. A focused 400-character comment with a specific insight will outperform a rambling 1,200-character comment every time. For more on how comments affect your reach, see our LinkedIn algorithm breakdown.

LinkedIn Connection Request Character Limit

Free accounts get 200 characters for connection request messages. Premium and Sales Navigator users get 300 characters. In both cases, that's roughly one to two sentences.

In 2026, LinkedIn introduced another constraint: free accounts can only send 5 personalized connection messages per month. After that, you can still send requests — but without a note attached.

This means every personalized message needs to earn its spot. The formula is simple: mention something specific about the person (a post, their role, a mutual connection) and state why you want to connect. Skip the pitch — a connection request is not a sales email.

For templates and strategies, see our detailed LinkedIn connection request message guide.

LinkedIn InMail Character Limit

InMail subject lines allow 200 characters and the body allows 1,900 characters. InMails are available to Premium, Sales Navigator, and Recruiter account holders.

Keep subject lines short and specific — under 50 characters tends to perform best even though you have 200 available. The body gives you enough room for a proper cold outreach message: context, relevance, value proposition, and a clear ask.

Tips for Writing Within LinkedIn's Limits

Knowing the character limits is step one. Writing effectively within them is the real skill. Here are practical strategies:

• Use a character counter. Pollen's free LinkedIn character counter shows your count in real time and warns you when you're approaching the limit for posts, headlines, and other fields.
• Front-load the important content. Every LinkedIn field has a "visible" zone (before "See more" or before truncation) and a "hidden" zone. Put your strongest material in the visible zone.
• Use line breaks and formatting. White space makes content easier to scan on mobile. Pollen's LinkedIn post formatter can add bold text, bullet points, and clean line spacing to maximize readability.
• Treat the first 210 characters of every post as your headline. If those two lines don't earn a click, the other 2,790 characters are invisible.
• For longer content, use articles. LinkedIn articles have no character limit and support rich formatting including headers, images, and embedded media.
• Draft in a doc, then paste. Writing directly in LinkedIn makes it easy to accidentally publish before you're ready. Draft elsewhere, check your character count, then paste.

Key Takeaways

• LinkedIn posts allow 3,000 characters, but only the first ~210 characters show before "See more" on mobile — make your opening line count

• The About section gives you 2,600 characters, but only the first ~300 are visible above the fold
• Comments allow 1,250 characters — longer, substantive comments rank higher in LinkedIn's algorithm
• Connection requests are 200 characters (free) or 300 characters (Premium), with free accounts limited to 5 personalized messages per month in 2026
• InMail gives you 200 characters for the subject and 1,900 for the body
• Use a character counter to stay within limits and a post formatter to maximize readability within the space you have
