LinkedIn About Section Character Limit 2025

Most people open your LinkedIn profile and make a decision in seconds.

Do you look credible? Do you get what they need? Or are you just another generic profile?

The place where that decision happens is the About section.

It’s where attention either turns into trust or disappears.

The challenge? In 2025, character limits and attention span of 8.25 seconds shape how much of your story actually gets seen.

This guide breaks down those limits and shows you how to use them to build an About section that converts.

Definitions and Key Limits

LinkedIn About Section Character Limit (Summary)

Max: 2,600 characters.
Best range: 1,800–2,200 characters (≈ 300–350 words).

Why not just max out?

Because LinkedIn truncates text. On desktop, readers see only the first ~300 characters before “See more.” On mobile, even less.

So your first 3–4 lines must act as a hook.

Example 1 Weak (Overstuffed):

“I am a dynamic, enthusiastic, passionate leader with a proven track record of delivering cross-functional business value across multiple verticals and stakeholders in the ever-evolving corporate ecosystem…”

Example 2 Strong (Optimized):

“Most B2B founders burn 10+ hours weekly chasing cold leads. I help them flip that wasted time into warm LinkedIn conversations that actually convert.”

Same length. Different impact.

LinkedIn Post Character Limit: The Core of Your Content

Posts: 3,000 characters
Comments: 1,250 characters
Articles: Unlimited (but audience drops after ~5,000 words)

Posts = dynamic trust-building.

About section = static proof.

A great loop looks like this:

Write posts that echo your About section’s positioning.
Posts bring readers to your profile.
Your About section converts curiosity into credibility.

Mini Framework:

Use posts for stories, opinions, frameworks.
Use the About for positioning, proof, CTA.

LinkedIn Headline Character Limit: Your Professional Billboard

Limit: 220 characters

Think of the headline as your billboard on the LinkedIn highway.

It shows up in:

Search results
DMs
Comments
“People you may know”

Most people waste it with titles:

“Consultant | Coach | Author”

That communicates nothing.

Formula for a high-performing headline:

[Audience] + [Outcome] + [Proof]

Example:

Helping B2B SaaS founders 5× LinkedIn visibility | Driving outbound pipeline with OutX.ai | 24× ROI

That’s clarity, niche focus, and measurable authority.

LinkedIn Messaging Character Limits

InMail subject line: 200 characters
InMail body: 2,000 characters
Connection request note: 300 characters

This is where micro-copy drives big outcomes.

Bad Connection Note:

“We are a global award-winning AI provider serving multiple verticals. Would like to connect.”

Reads like spam.

Better Connection Note (under 300 chars):

“Loved your post on scaling SDR teams. Curious have you tried automating LinkedIn engagement? I’ve seen it save 10+ hours a week.”

Personal. Human. Specific.

How to Optimize Your About Section

Determine Character Target

Don’t max out the 2,600.

Aim for 1,800–2,200 characters.

This gives you room for:

A bold hook (2–3 lines)
Proof bullets (3–6 metrics or outcomes)
A CTA (final 2 lines)

Think of it like a sales page: hook attention, build trust, direct action.

Incorporate Keywords

LinkedIn = search + relevance.

Your About section is your SEO copy.

Keyword Placement Grid:

Opening lines: Must include your #1 keyword (highest weight).
Bullets: Sprinkle 2–3 secondary keywords.
CTA: Reinforce with branded phrase or niche keyword.

Examples:

“LinkedIn automation for B2B founders”
“AI social listening and monitoring tool”
“Outbound growth engine for SaaS”

Bad: stuffing “LinkedIn growth” 12 times.

Good: repeating it naturally 2–3× across sections.

Structure Your Section

Use the 3-part winning structure:

Hook (Problem + Promise):

“Most founders post daily but still get ignored. I help them turn likes into leads without burning hours.”
Proof (Bullets or tight sentences):
- 5× profile visibility in 90 days
- 10+ hours back weekly through automation
- 2× warmer leads from contextual engagement
CTA (Direct + Simple):

“DM me the word growth for a quick walkthrough.”

Keep It Engaging

Engagement is visual. People don’t read walls of text.

Do:

Break lines often.
Write in short sentences.
Use bullets for proof.
Sprinkle emojis for rhythm.

Don’t:

Drop a 15-line block.
Write like a résumé.
Over-decorate with symbols.

Example Boring block:

“I am an experienced sales leader with a proven track record in helping companies….”

Example Engaging flow:

“I help B2B sales teams:

⚡ Save 10+ hours weekly

📈 2× response rates

🎯 Win deals without spamming”

Advanced Tips for a Winning About Section

Emojis & Bullets

Emojis = emphasis, not decoration.

One emoji = one character.

Good:

⚡ Save time

📈 Grow visibility

🎯 Close pipeline faster

Bad:

🔥🚀💯🙌✨🔥🔥🚀🚀

Use bullets to make proof digestible.

Call-to-Action Placement

Never bury your CTA.

Your last two lines should always point to the next step.

CTA Options:

“DM me growth to see how it works.”
“Check out outx.ai/social-listening-linkedin.”
“Message me if you’re scaling outbound.”

Mini Formula: Action word + trigger word + channel.

SEO Considerations

LinkedIn profiles rank on Google.

Checklist:

Use long-tail phrases (“LinkedIn automation for B2B SaaS founders”).
Repeat core keyword 2–3×.
Keep sentences human.

Search engines love clarity. Humans do too.

Common Mistakes People Still Make in 2025

Treating the About Section Like a Résumé

LinkedIn is not a CV database.

Nobody wants to read 20 years of job history crammed into 2,600 characters.

The goal is positioning, not chronology.

If someone wants your résumé, they’ll ask.

Your About section should answer one thing: Why should I trust you now?

Writing for Themselves Instead of the Reader

The worst mistake? Making it all about you.

“I am passionate about cross-functional collaboration and skilled in stakeholder management.”

That’s noise. Readers are asking: What can you do for me?

Flip the script:

“I help founders win back 10+ hours weekly by automating repetitive LinkedIn tasks.”

Now it’s reader-focused.

Ignoring the Hook

LinkedIn truncates after a few lines.

If your first sentence is flat, the rest will never be seen.

Bad hook:

“I am an experienced professional with a proven track record…”

Strong hook:

“Most founders are losing opportunities on LinkedIn without even realizing it.”

Overloading With Emojis or Buzzwords

Too many emojis = clown show.

Too much jargon = snoozefest.

Good = 1 emoji per idea.

Good = plain English, clear proof.

FAQs for 2025

How Many Characters Are Allowed in the About Section?

2,600 max. Best range: 1,800–2,200.

Do Emojis Count Toward the Limit?

Yes. Each emoji = one character.

Can I Add Links?

Yes, but they’re not clickable. Use short branded URLs:

outx.ai/social-listening-linkedin

Is There a Word Count Sweet Spot?

Yes. 300–350 words. Enough for context, short enough for scanning.

Should I Write in First or Third Person?

Always first person.

Third person sounds corporate and distant.

How Often Should I Update My About Section?

Every 6–12 months, or when your positioning changes. LinkedIn rewards freshness.

Do Keywords Really Matter?

Yes. LinkedIn search is keyword-driven. Without them, you won’t rank in recruiter or buyer searches.

Can I Copy Someone Else’s Style?

Use inspiration, but don’t copy. Authenticity wins. Readers can smell templates.
