LinkedIn Character Limit Guide 2025

LinkedIn Post Character Limit

LinkedIn allows up to 3,000 characters for regular posts. However, there's a crucial detail most users miss: LinkedIn truncates posts at approximately 1,300 characters with a "See more" button.

The "See More" Threshold (1,300 Characters)

When your post exceeds roughly 1,300 characters, LinkedIn collapses it with a "...see more" link. This is why your hook (the first 1-2 sentences) is absolutely critical. If readers don't click "see more," they'll never read your full content.

LinkedIn Article Character Limit

LinkedIn Articles (published via the "Write article" feature) support up to 125,000 characters (approximately 20,000-30,000 words). Articles also support:

• Rich formatting (bold, italic, headers)
• Images and embedded media
• Bullet points and numbered lists
• Code blocks (limited support)

LinkedIn Profile Section Limits

Headline

220 characters - Your headline appears below your name and is one of the most visible parts of your profile. Make it count with keywords and value propositions.

About Section (Summary)

2,600 characters - This is your elevator pitch. Use it to tell your professional story, highlight achievements, and include relevant keywords for SEO.

Job Description

2,000 characters per position - Describe your role, responsibilities, and accomplishments for each job listing.

LinkedIn Comments and Messages

Comments

1,250 characters - LinkedIn comments are limited to 1,250 characters. Comments longer than ~300 characters also get truncated with "...see more."

Direct Messages

8,000 characters - LinkedIn InMail and direct messages support up to 8,000 characters, giving you plenty of room for detailed conversations.

Company Page Limits

• Company description: 2,000 characters
• Company posts: 3,000 characters (same as personal posts)
• Showcase page description: 200 characters

Hashtag Limits

While LinkedIn doesn't officially limit hashtags, best practice is 3-5 hashtags per post. Too many hashtags can make your post look spammy and may hurt engagement.

LinkedIn Video Limits

While not character limits, here are LinkedIn's video constraints:

• Video length: 3 seconds to 10 minutes (native upload)
• File size: Maximum 5 GB
• Video caption: 2,000 characters
• Aspect ratio: 1:2.4 to 2.4:1 (square 1:1 works best)

Optimal Post Length for Engagement

Character limits tell you the maximum, but what's the optimal length for engagement?

How to Check Your Character Count

Most text editors don't show real-time character counts. Here are easy ways to check:

1. Use LinkedInBoost Formatter: Our free formatter tool shows live character count as you type
2. Google Docs: Tools → Word Count → Character count
3. Microsoft Word: Review → Word Count
4. Online tools: CharacterCountOnline.com or WordCounter.net

What Happens if You Exceed the Limit?

LinkedIn will simply prevent you from posting if you exceed the character limit. Your post button will be grayed out until you reduce the character count. There's no auto-truncation—you must manually edit your content.

Tips for Maximizing Your Character Limits

1. Front-Load Important Information

Put your hook, main message, and CTA in the first 1,300 characters. Treat everything after as bonus content.

2. Use Line Breaks Strategically

Short paragraphs (2-3 sentences) with line breaks make content more scannable. This helps you pack more value into fewer characters.

3. Leverage Emojis

Emojis are single characters but convey meaning visually. Use 2-5 per post to add personality without eating character count.

4. Edit Ruthlessly

Every sentence should add value. Cut filler words, redundant phrases, and unnecessary details. "Very good" becomes "excellent."

5. Use Numbers and Lists

"5 tips" is more compelling and concise than "Here are some tips I want to share with you." Lists also improve readability.

The Bottom Line

LinkedIn's 3,000-character limit gives you plenty of room for detailed posts, but the real magic happens in the first 1,300 characters. Master that space, and you'll dramatically improve your post performance.

Remember: More characters doesn't always mean better content. Some of the highest-performing posts on LinkedIn are under 500 characters. Focus on value, not word count.
