LinkedIn Character Limit

The LinkedIn post character limit is 3,000 characters. Articles allow up to 125,000 characters (with a 100-character title limit). Comments cap at 1,250 characters, and your profile headline gets 220.

That 3,000-character post limit is the one everyone searches for, and it's the one LinkedIn enforces most visibly — a red counter appears as you approach it. But the number that actually shapes your reach is smaller: LinkedIn truncates posts after roughly 210 characters with a "...see more" link. Everything after that fold is invisible unless someone taps.

Here's every LinkedIn character limit, verified against LinkedIn's own help pages and creator documentation for 2026.

The "see more" fold matters more than the 3,000 cap

LinkedIn truncates posts at approximately 210 characters on mobile and slightly more on desktop. Everything after that disappears behind "...see more." This means your first two lines are your entire pitch to a scrolling reader.

The posts that perform well on LinkedIn almost always front-load a hook or a specific claim in that opening window. Vague intros like "I've been thinking about leadership lately..." waste the only real estate that's guaranteed to be seen.

Here's the practical breakdown:

• First ~210 characters: Always visible. This is your headline, your hook, your reason for someone to stop scrolling.
• 210-1,500 characters: Only seen if someone taps "see more." Most engaged readers will get this far.
• 1,500-3,000 characters: Deep readers only. Good for detailed stories, frameworks, or lists, but don't put critical information here.

If you're consistently writing posts that push near 3,000, use the character counter to check length and make sure your strongest content is above the fold.

Articles vs posts — different tools, different limits

LinkedIn articles and LinkedIn posts are separate formats with very different limits:

Articles are LinkedIn's answer to blogging. The 125,000-character body limit is roughly 20,000 words — more than enough for any professional piece. Article titles cap at 100 characters, which is tight for descriptive headlines. If your title runs long, check it against the limit before publishing.

The distinction that matters for most people: posts get immediate feed distribution but have a short shelf life. Articles get indexed by search engines and can drive traffic for months, but they don't get the same initial feed push. Pick the format based on whether you want reach now (post) or discoverability later (article).

Comments: 1,250 characters

LinkedIn comments allow 1,250 characters — roughly 200 words. That's enough for a substantive reply but short enough that you can't write an essay. A few things that count toward the limit:

• Mentions (@name) count their full text
• Hashtags count their full text including the # symbol
• Emoji count as characters (usually 1-2 code points each)
• Line breaks count as characters

Thoughtful comments on other people's posts are one of the most effective ways to grow on LinkedIn. But a comment that gets cut off mid-sentence because you didn't check the length undermines the point. The character counter takes two seconds.

Profile headline: 220 characters of prime real estate

Your LinkedIn headline is the 220-character line that appears directly under your name — in search results, in comments, in connection requests, everywhere. It's the most visible text on your entire profile.

Most people waste it on their job title alone. "Marketing Manager at Acme Corp" is 33 characters. You have 187 left. Use them. A headline like "Marketing Manager at Acme Corp | Helping B2B SaaS companies cut CAC by 40% through organic content" tells someone exactly what you do and why they should care.

If you want to format your headline with special characters or Unicode styling, the LinkedIn text formatter lets you add bold or italic text — though keep in mind that some Unicode characters count as multiple code points against your 220 limit.

About section and connection notes

The About / Summary section gives you 2,600 characters — roughly 400 words. This is where you tell your professional story, and unlike the headline, it doesn't appear everywhere. Someone has to visit your profile and scroll to read it. Use it for detail, not hooks.

Connection request notes are tight at 300 characters. That's 2-3 sentences. The best connection notes are specific: mention where you met, what you have in common, or why you're reaching out. Generic notes ("I'd like to add you to my professional network") waste the limited space and get ignored.

InMail splits into a 200-character subject line and a 1,900-character body. The subject line matters most — it determines whether someone opens your message at all.

How LinkedIn compares to other platforms

LinkedIn's 3,000-character post limit sits in the middle of the social media range. Here's context:

• Twitter / X: 280 characters (free) / 25,000 (Premium) — Twitter character limit
• Facebook: 63,206 characters — Facebook character limit
• Instagram: 2,200 characters — Instagram caption character limit
• Threads: 500 characters — Threads character limit

The difference is that LinkedIn's audience expects longer, more substantive content — so the 3,000 cap feels tighter in practice than platforms with smaller limits but different norms. Write to the character counter, not to the red warning, and put your best material above the fold.
