LinkedIn Character Limits: Posts, Articles, Headlines, and the See-More Fold
LinkedIn feed posts cap at 3,000 characters, but only the first 140 characters appear on mobile before the "see more" fold cuts in. That threshold — shorter than most opening sentences — is the real constraint. Paste any draft into the word counter on the homepage to see the count before you publish.
The full limit map
Six surfaces on LinkedIn operate under distinct limits, and mixing them up is what causes posts to get truncated mid-point and profiles to feel sparse:
- Feed post: 3,000 characters — roughly 450 to 600 words of standard prose
- Article body: 110,000 characters, long enough for a multi-chapter guide or a detailed white paper
- Headline: 220 characters, which follows your name into every comment thread, connection request, and search result
- About / summary section: 2,600 characters, or about 400 to 430 words
- Comment: 1,750 characters per reply
- InMail body: 2,000 characters
That headline figure deserves a second look. The 220-character ceiling is more generous than almost anyone uses. A bare job title like "Senior Marketing Manager at Acme Corp." runs to about 40 characters. That leaves 180 characters sitting empty. Multiple third-party trackers including Kondo's LinkedIn character limit guide have confirmed these limits remain stable as of 2025.
Where the fold actually cuts
The "see more" truncation point is the most operationally significant number in this list, and it is not the same across devices.
On desktop, LinkedIn shows approximately 210 characters before folding. On mobile, that drops to roughly 140 characters. AuthoredUp's analysis of 372,126 LinkedIn posts published between September 2025 and February 2026 found that posts between 1,301 and 2,500 characters generated a 27 percent higher engagement rate than posts under 400 characters — which suggests readers do click through when the opening earns it. The fold is the gate; the 140-character mobile threshold is the lock.
Treat those first 140 characters as your headline, not your setup. "I've been thinking a lot about X lately and wanted to share some reflections" is 80 characters of nothing. Your most specific, concrete, or counterintuitive claim should land before the cut.
One practical check: paste your draft into the word counter on the homepage, look at the raw character count, and then manually count to the 140th character. That is exactly where a mobile reader will stop unless you give them a reason to continue.
Headlines and the 220 rule
LinkedIn's internal search algorithm gives material weight to your headline text. The platform shows your full 220-character headline on your profile page, but truncates it to roughly 60 to 70 characters in search results, connection request previews, and the comment byline that appears next to every reply you post.
That 60-character window matters. If your specialty or differentiator lives at character 100, it is invisible in the places where new connections first encounter you. A structure that works: lead with your primary keyword or role, add a pipe separator, then your industry or specialty, then a concrete proof point. "Product Manager | B2B SaaS | 3 products launched from 0 to $8M ARR" runs to about 68 characters and places the most searchable term first.
If you are not sure how long your current headline is, paste it into the word counter on the homepage — the character count updates as you type.
Posts vs. articles: where the line is
The 3,000-character post limit and the 110,000-character article limit are not interchangeable, and the format you choose shapes how the content is distributed.
Feed posts enter the algorithmic queue. They get amplified by early engagement — comments, reactions, shares — and most of their reach happens within 48 to 72 hours. A post from Tuesday morning has effectively decayed by Friday. That volatility makes posts the right format for timely opinions, short lessons, announcements, and questions.
Articles sit at a permanent URL on your profile under the "Articles and Activity" tab. They do not get the same algorithmic feed push, but they accumulate. Recruiters and potential clients who review your profile before reaching out will often read an article; they rarely see a post from six months ago. If you are writing something longer than 3,000 characters that you expect to reference or share in six months, publish it as an article.
The 110,000-character article limit is, for most practical purposes, unconstrained. A 5,000-word article — detailed enough to be a full industry guide — uses fewer than 35,000 characters.
Comments: the underestimated surface
At 1,750 characters, LinkedIn comments are substantially longer than most people write. The average LinkedIn comment runs to two or three sentences — often under 100 characters. That gap matters because comments compound reach. When you leave a thoughtful 400-character reply that adds a specific data point or a counterexample to the original post, you appear in the feeds of that poster's connections who engage with their content. Your comment functions like a micro-post attached to someone else's distribution.
The strategic implication: if you are trying to build visibility without posting daily, substantive commenting — replies that use 200 to 400 of the available 1,750 characters — generates genuine impressions. A three-sentence comment that adds a concrete case study will outperform a "great point!" that uses 12 characters.
LinkedIn does not truncate comments with a "see more" fold the way it folds post bodies, so a longer comment is shown in full. That makes comments one of the few LinkedIn surfaces where length does not create a click barrier.
Comparing LinkedIn to the rest of the landscape
LinkedIn's 3,000-character post limit is roughly ten times the length of an X post and about six times shorter than Facebook's theoretical post maximum. That position — substantially longer than most short-form platforms but still bounded — is what gives LinkedIn its distinct voice. A post long enough to tell a complete story, short enough to read in three minutes.
A 2,000-character LinkedIn post runs to about 330 words of standard English. That is enough room for a four-part structure that performs consistently well on the platform: the specific claim or observation, the backstory or context, the friction or complication, and the takeaway. You can draft that in any text editor, check the character count with the word counter on the homepage, and know before you paste it into LinkedIn whether it fits.
The About section at 2,600 characters is enough for five substantive paragraphs. Most LinkedIn profiles use fewer than 500 characters in this section — a 2,100-character gap that represents roughly three paragraphs of context a recruiter or potential client never sees.
