LinkedIn is weird. You get 3,000 characters for a post, but only about 210 show before people have to click "see more." That means your first couple of sentences matter way more than anything else you write.

I've spent a lot of time figuring out what works on LinkedIn - both for personal posts and company pages. Here's everything I've learned about character limits and how to use them strategically.

LinkedIn Posts: What Actually Works

3,000 characters sounds like a lot until you try to say something meaningful. Here's the reality:

  • Maximum length: 3,000 characters
  • Visible before truncation: ~210 characters (desktop) / ~140 (mobile)
  • Hashtags: 3-5 works best, don't overdo it
  • Media: Images, videos, documents, polls all work

How I Structure My Posts

This is the formula I've settled on after a lot of trial and error:

  1. Hook (first 210 characters): This is everything. If people don't click "see more," nothing else matters.
  2. Body: The actual value - story, insight, lesson
  3. White space: Line breaks everywhere. Walls of text don't get read.
  4. CTA: End with a question or clear next step
  5. Hashtags: 3-5 at the end, keep them relevant

Optimal Post Length

Here's what I've observed about engagement:

  • Short posts (under 300 characters): Good for polls and quick questions
  • Medium posts (1,200-1,600 characters): Sweet spot for thought leadership
  • Long posts (2,000+ characters): Stories and detailed insights

The "just write whatever length fits the message" advice is true in theory, but in practice, medium-length posts tend to perform best.

Profile Character Limits

Your profile has different limits for each section. Here's the breakdown:

LinkedIn Articles

LinkedIn Articles are a completely different beast from posts. You get about 125,000 characters - that's roughly 25,000 words or about a short book.

  • Article title: 100 characters
  • Article body: ~125,000 characters
  • Formatting: Headers, bullets, quotes, links, images
  • Cover image: 1920x1080 pixels recommended

When to Use Articles vs Posts

Use Posts ForUse Articles For
Quick updatesIn-depth analysis
Engagement/discussionHow-to guides
Polls and questionsCase studies
Daily contentThought leadership
Personal storiesResearch findings

Honestly, posts get more engagement than articles for most people. But articles are great for SEO and establishing expertise.

Company Pages

Company pages have slightly different limits:

  • Company Name: 100 characters
  • Tagline: 120 characters
  • Description (About): 2,000 characters
  • Company post: 3,000 characters (same as personal)
  • Showcase page description: 200 characters

Messages & Comments

Direct Messages

  • Regular message: 8,000 characters
  • Subject line: 200 characters
  • Connection request note: 300 characters
  • InMail subject: 200 characters
  • InMail message: 1,900 characters

That 300 character connection request limit? It's why most connection messages are so terrible. But it forces you to be concise.

Comments

  • Post comment: 1,250 characters
  • Article comment: 1,250 characters
  • Comment replies: 1,250 characters

What Actually Works

For Posts

  1. Hook immediately: Those first 210 characters determine everything
  2. Use line breaks liberally: Nobody reads walls of text
  3. Ask questions: The algorithm loves comments
  4. Time your posts: Tuesday-Thursday, 8-10 AM works for B2B
  5. Stay on LinkedIn: External links hurt reach

For Headlines

  • Include your job title and industry
  • Add what makes you different
  • Use keywords people actually search
  • Skip the buzzwords ("guru," "ninja," etc.)

For the About Section

  • Start with a hook (same principle as posts)
  • Tell your story, not just your resume
  • Include numbers and achievements
  • End with a call-to-action
  • Use keywords naturally

Frequently Asked Questions

What is the LinkedIn post character limit?

3,000 characters. But honestly, only the first 210 matter - that's what shows before "see more." If your hook doesn't make people click, nothing else matters.

How long can a LinkedIn headline be?

220 characters. This is prime real estate - it shows directly below your name on your profile and in search results. Use it wisely.

What is the LinkedIn About section limit?

2,600 characters. But only about 300 show before "see more," so start with your most compelling stuff.

How long can a LinkedIn article be?

Around 125,000 characters - that's roughly 25,000 words. Plenty of room for in-depth content, guides, and thought leadership pieces.

What is the ideal LinkedIn post length?

1,200-1,600 characters tends to perform best for engagement. But the first 210 characters are what really matter - that's your hook.

Do hashtags count toward the character limit?

Yes, they eat into your 3,000 characters. Use 3-5 relevant ones at the end of your post. More than that looks spammy and wastes space.
