LinkedIn Character Limits: Every Limit You Need to Know

You're mid-post and LinkedIn cuts you off. Or worse: you write 2,800 characters and realize only 210 of them show before the fold.

Every LinkedIn field has a character limit. Some are obvious (posts: 3,000). Some will catch you off guard (poll options: 30 characters). And the number that actually matters most isn't the limit itself. It's the cutoff point where LinkedIn hides the rest behind "see more."

Here's every limit, every cutoff, and the data on which post lengths actually drive engagement.

LinkedIn Character Limits: Quick Reference Table

*LinkedIn's comment limit varies by source (1,250-1,750). We've verified it at 1,250 characters in testing as of March 2026, but LinkedIn may adjust this without announcement.

The "Visible Before Cutoff" column is the one most guides skip. It's also the one that matters most for engagement. Your first 210 characters decide whether anyone reads the rest.

LinkedIn Post Character Limit: 3,000 Characters

The hard limit for a standard LinkedIn post is 3,000 characters, including spaces. LinkedIn increased this from 1,300 in June 2023.

But 3,000 is the ceiling, not the target.

On desktop, roughly 210 characters appear before the "...see more" prompt. On mobile, it's closer to 140. That means your first two to three lines are doing all the work. If they don't stop the scroll, the other 2,800 characters are invisible.

Three things to know:

1. Spaces count. Every space, line break, and emoji counts toward 3,000.
2. Emojis count as 2+ characters. A standard emoji takes 2 characters. Flag emojis and skin-tone variants can take 4-7.
3. You can't go over. LinkedIn disables the post button when you exceed the limit. No workaround, no exceptions. If you need more space, write a LinkedIn article instead.

A real-time character counter eliminates the guesswork. AuthoredUp's post editor  shows your count as you type and previews exactly where the fold hits, so you can nail your hook before publishing.

What's the Best LinkedIn Post Length? (The Data)

The character limit is 3,000. But what length actually performs best?

We analyzed 372,126 LinkedIn posts from personal profiles (September 2025 through February 2026, posts with at least 1 impression) and measured engagement rate by character count.

The pattern is clear: longer posts perform better, up to a point.

Posts between 1,301 and 2,500 characters hit the sweet spot: highest engagement rate (2.61-2.67%), strong impressions, and 5-6 median comments. That's roughly 200-400 words.

Posts that use nearly the full 3,000 characters still perform well (2.62% ER), but engagement rate dips slightly compared to the 2,001-2,500 range. The highest-performing posts aren't the ones that fill every available character. They're the ones that say what needs to be said and stop.

Short posts (under 400 characters) underperform across the board: lower engagement rate (2.10%), fewer impressions (575 median), and just 1 median comment. If your post is under 400 characters, it's likely too short to trigger meaningful engagement.

The takeaway: aim for 1,300-2,500 characters. That gives you enough room to build an argument, tell a short story, or walk through a framework, while keeping engagement rates at their peak.

LinkedIn Headline Character Limit: 220 Characters

Your headline gets 220 characters. But in search results, connection requests, and comment sections, only about 60-70 characters display.

This means your headline has two jobs:

1. The first 60-70 characters must communicate who you are and what you do. This is what people see in most contexts.
2. Characters 71-220 add detail and keywords that help you appear in LinkedIn search, even if most people never read them.

Front-load the important stuff. "Head of Marketing at [Company] | B2B Growth" works. "Passionate about leveraging synergies to drive transformative outcomes in the marketing landscape" does not.

Common mistakes:

• Writing a full 220-character headline when only 60 characters show
• Using the headline as a tagline instead of a description
• Skipping keywords that help you appear in search

To test how your headline looks before saving it, use the LinkedIn Headline Optimizer.

LinkedIn About Section Character Limit: 2,600 Characters

The About section (formerly "Summary") allows 2,600 characters. Only about 300 characters display before the "See more" button.

Those first 300 characters are your pitch. If they don't compel someone to click, the rest doesn't matter.

Structure that works:

• First 300 characters: Who you are, what you do, and why someone should care. This is the part people see.
• Middle section: Your background, expertise, and what makes you different. Use short paragraphs and line breaks.
• Final lines: A clear call to action. What should someone do after reading this? (Email you? Book a call? Visit your site?)

You can format text in your About section using unicode characters: bold, italic, and special symbols. The LinkedIn Text Formatter handles this, since LinkedIn doesn't offer native formatting in the About section.

LinkedIn Comment Character Limit: 1,250 Characters

Comments allow up to 1,250 characters, and unlike posts, the full text displays with no "see more" truncation.

This matters more than most people realize. Thoughtful, longer comments get noticed by both the post author and the algorithm. A 500-character comment that adds a genuine perspective stands out in a sea of "Great post!" replies.

Strategic commenting is one of the most underrated LinkedIn growth tactics. The 1,250-character limit gives you plenty of room to share a relevant experience, add data, or respectfully disagree. Use it.

Other LinkedIn Character Limits

LinkedIn Articles: The body allows roughly 110,000 characters, effectively unlimited for practical purposes. Article titles cap at 150 characters. Articles are better for long-form content that exceeds the 3,000-character post limit, but posts consistently outperform articles in reach and engagement.

Connection Request Notes: 300 characters. Tight. Be personal and specific. Generic requests get ignored; a sentence about why you're connecting gets accepted.

Direct Messages: 8,000 characters. Far more than you'll need. Keep messages short. Longer DMs have lower response rates.

InMail: Subject lines cap at 200 characters, body at 2,000. Front-load the value proposition in the subject line.

Company Page Tagline: 120 characters. Treat it like a headline: what do you do, for whom?

Company Page Description: 2,000 characters. Include keywords for LinkedIn's internal search. This is where you describe your business in detail.

Polls: Questions get 140 characters, each option gets 30. Brevity isn't optional here; it's enforced. Plan your question and options carefully before typing them in. 

Recommendations: 3,000 characters. Be specific: mention projects, outcomes, and what made this person's contribution distinctive.

Experience Descriptions: 2,000 characters per role. Lead with achievements, not responsibilities.

When to Post Matters Too

Knowing your character limits is one thing. Knowing when to post is another. Posting at the right time can significantly affect how many people see your first 210 characters.

Frequently Asked Questions

Does LinkedIn count spaces in the character limit?

Yes. Spaces, line breaks, and all whitespace characters count toward the total limit for every LinkedIn field.

Do emojis count differently toward the character limit?

Most standard emojis count as 2 characters. Complex emojis (flags, skin-tone variants, family combinations) can count as 4-7 characters. If you're near the limit and using emojis, check your count with a post preview tool.

How do I post more than 3,000 characters on LinkedIn?

You can't exceed 3,000 characters in a standard post. If you need more space, use a LinkedIn article (up to ~110,000 characters) or split your content into a multi-part series. Another option: create a carousel/document post where each slide covers a section of your argument.

Is 500 words too long for a LinkedIn post?

No. 500 words is roughly 2,500-3,000 characters, which is within the limit. Our data shows posts of 2,001-2,500 characters (about 300-400 words) hit the engagement sweet spot. But quality matters more than length: a focused 300-word post outperforms a rambling 500-word one.

Did LinkedIn increase the post character limit recently?

LinkedIn increased the limit from 1,300 to 3,000 characters in June 2023. As of March 2026, it remains at 3,000. No further changes have been announced.

Is the character limit different on mobile vs. desktop?

The hard limit is the same across devices. The "see more" cutoff is shorter on mobile (~140 characters) compared to desktop (~210 characters). Write your hook to work within the mobile cutoff to reach both audiences.

Can I format text within the character limit?

Yes. Unicode formatting (bold, italic, strikethrough) doesn't add extra characters beyond the styled characters themselves. Formatting actually helps readability within your character budget. Use our free LinkedIn Text Formatter tool to apply formatting.
