The short version: LinkedIn gives you 2,600 characters for your About section, but only the first two or three lines (roughly 125 to 300 characters depending on device) show before someone has to click “see more”. The right length depends on what you’re using LinkedIn for. Job seekers can often get away with 150 to 300 words. Consultants, coaches, and anyone who needs to be found in LinkedIn search should be writing closer to the full 2,600 characters, because the platform reads every word of it even if a human never scrolls that far.
What LinkedIn lets you write
LinkedIn’s About section has a hard cap of 2,600 characters, spaces included. That’s around 400 to 450 words. Most people never get close to it. I’ve looked at hundreds of profiles doing audits for clients over the years, and the average summary I see sits at somewhere between 80 and 150 words, mostly job titles and a sentence about “passion for helping people.”
Here’s the bit that trips people up: the character limit isn’t the same as the visible limit. On desktop, you see roughly the first 265 to 300 characters before the “see more” link appears. On mobile it’s less, often under 150 characters, sometimes cutting off mid sentence. So you’re really writing two things at once: a two line hook that has to work on its own, and a longer body that most visitors will never open.
The length depends on why you’re on LinkedIn
This is where most advice goes wrong. Career coaches tell everyone to “keep it short and punchy,” which is decent advice if you’re job hunting and a recruiter is skimming forty profiles in an evening. It’s terrible advice if you’re a freelancer, coach, or business owner trying to get found by people searching LinkedIn for what you do.
Split it like this:
- Job seekers: 150 to 300 words. Lead with the role you want, not the one you had. Three short paragraphs beats one dense block.
- Consultants, freelancers, coaches: 350 to 500 words, using most or all of the 2,600 characters. You need the space for keywords because LinkedIn’s internal search rewards keyword density in your About section.
- Employees not actively looking for anything: 100 to 200 words is fine. You’re not trying to rank for anything, you’re just filling in a page that colleagues and clients occasionally check.
- Speakers, authors, people building a personal brand: full length, close to 2,600 characters, because your summary often gets copied straight into event bios and press requests. I’ve had my own About text lifted word for word into a conference programme more than once.
A real example: what happened when I cut mine down
Back in 2019, someone on a LinkedIn training I was running told me my summary was “too long, nobody reads that much.” I took the feedback seriously and cut it from around 1,900 characters down to under 400, three tight paragraphs, very clean, very scannable. It looked great.
Over the following six weeks my profile views dropped by close to a third, and inbound messages from the summary specifically (people would often say “I read your About section and…”) almost stopped. I put back roughly 1,400 characters, this time deliberately packed with the phrases people search for, things like “LinkedIn training,” “keynote speaker,” “AI for small business,” repeated naturally through the text rather than crammed once at the top. Within a month, profile views were back above where they’d started.
The lesson wasn’t “longer is always better.” It was that cutting for the sake of looking tidy, without understanding that LinkedIn’s search treats your About section as one of the heaviest weighted fields on the whole profile, cost me visibility for no real gain in readability. Nobody was struggling to read 1,400 characters. They just weren’t finding me in search when it was 400.
The uncomfortable bit nobody puts in these guides
Most people writing about this only think about the human reading experience, so they land on “keep it short.” Almost none of them mention that LinkedIn’s search algorithm doesn’t care whether a human enjoys reading your summary. It’s indexing text. A short, elegant, three sentence About section might read beautifully and rank you nowhere, because there simply isn’t enough keyword-rich text in it for the algorithm to match against searches.
So the real answer is that you’re writing for two completely different readers at the same time, a human who will read maybe two lines before deciding whether to click “see more,” and a search index that reads all 2,600 characters and uses them to decide whether you show up when someone searches “fractional CMO Manchester” or “AI consultant for small business.” Most advice picks one of those readers and ignores the other. You need both.
Step by step: work out your ideal length
- Decide your goal first. Job right now, or visibility over the next twelve months. This alone determines whether you’re aiming for 200 words or 500.
- Write your two line hook separately. Draft the first 250 characters as a standalone piece. Read it with nothing else attached. Would it make a stranger click “see more”?
- List eight to twelve search terms. The exact phrases someone would type to find a person doing what you do. Job title variations count too, “marketing director” and “head of marketing” are both worth including if you’ve held either.
- Write the body in three short blocks. Who you help, what you’ve done (with a number if you have one, “helped 40 SMEs cut ad spend by 20%” beats “results driven”), and how to work with you.
- Count your characters before you post. Paste the draft into a word processor and check the count. Under 300 total, you’re writing for job seekers or a light touch presence. Over 1,000, you’re writing for search.
- Read it back on mobile. Open your own profile on your phone before you finalise anything. What cuts off is what most people see.
Bullet points, paragraphs, or both
Both work. What matters more than format is that the first two lines aren’t wasted on your name and job title, since that information is already sitting directly above the About section on your profile. I still see profiles that open the summary with “John Smith is a marketing professional with over 15 years experience.” That’s dead space. LinkedIn already told the reader your name and job title thirty seconds ago.
A short paragraph as the hook, followed by three or four bullet points for proof (clients, results, notable projects), followed by a short closing paragraph with a way to get in touch, tends to perform well because it respects both the skimmer and the reader who scrolls the whole thing. This is the same logic behind good LinkedIn posts generally, which is worth understanding if you’re going to be active on the platform, and my piece on how to post on LinkedIn the right way covers the structure that keeps people reading past the first line, the same principle your summary needs.
What length does for different situations
If you’re job hunting, your summary sits alongside the rest of your resume and your profile, so it doesn’t need to carry every detail. It needs to make a recruiter want to open your experience section. If you’re wondering how the two pieces fit together, I’ve written a full walkthrough on how to add your LinkedIn profile to your resume without it looking bolted on, which matters more than most job seekers realise because a mismatched summary and CV is one of the fastest ways to lose credibility with a hiring manager.
If you’re building a business presence, the summary is doing double duty as an SEO asset and a landing page. That’s a different job entirely, and it’s why the “keep it under four sentences” advice, which is good for a CV cover letter, falls apart for anyone trying to be found by strangers searching LinkedIn cold.
A quick note on the rest of your profile setup
Length of your summary matters, but it sits inside a wider profile that needs the basics right too. If you’re not sure where your public profile link even lives so you can put it on a business card or email signature, that’s covered in what a LinkedIn profile URL is and how to find and fix yours. And once your summary is in good shape, staying visible depends on posting consistently, which is a separate question with its own answer in how often you should post on LinkedIn each week.
What I’d tell you if you only read this far
Don’t pick a word count because a guide told you to. Pick it based on whether you need LinkedIn to work as a search engine for you or as a quick confirmation that you’re a real, credible person. Job seekers can stay short. Anyone trying to be found needs to use most of the 2,600 characters they’ve been given, front loaded with two lines strong enough to earn the click, and the rest built around the exact phrases people type when they’re looking for someone exactly like you.
Frequently asked questions
How many words is 2,600 characters on LinkedIn?
Roughly 400 to 450 words, depending on average word length and how much punctuation and spacing you use. Most people never get close to using the full limit, which is often a missed opportunity for anyone relying on LinkedIn search to be found.
Is a short LinkedIn summary bad for recruiters?
No, a short summary of 150 to 300 words tends to work well for active job seekers because recruiters are skimming many profiles quickly and want a fast, clear picture. Short only becomes a problem when you’re relying on LinkedIn search rather than direct applications, since search rewards more text and more relevant keywords.
Should I write my LinkedIn summary in first or third person?
First person almost always reads better and builds more trust, since third person can come across as written by someone else about you. The exception is if your profile is being managed as a semi-official company representative page, where a slightly more formal third person tone sometimes fits the brand.
Does LinkedIn summary length affect how often you show up in search results?
Yes. LinkedIn’s search weighs text in your About section heavily when matching profiles to search terms, so a longer, keyword rich summary generally outperforms a short one for discoverability, even if the short one reads more cleanly to a human visitor.
