LinkedIn Comment Character Limit: 1,250 Characters (Verified 2026)
LinkedIn comment character limit: 1,250 characters, the most reported figure in 2026. Full verified table of LinkedIn limits for posts, headlines, and more.
By Commenti Team, linkedin growth research
The short version
- The LinkedIn comment character limit is 1,250 characters, the figure most independent sources report in 2026, though LinkedIn does not document it officially.
- LinkedIn posts allow 3,000 characters, headlines 220, About sections 2,600, connection request notes 300, and direct messages 8,000.
- A minority of sources report a 1,750 character comment limit, so treat 1,250 as the safe ceiling when drafting or templating comments.
- Effective comments use a fraction of the limit; long comments collapse behind a "see more" link and most readers never expand them.
- LinkedIn changes limits without announcement, so check the verified-as-of date on any character limit table before building templates around an exact number.
Frequently asked questions
What is the LinkedIn comment character limit in 2026?
1,250 characters is the limit most sources report as of July 2026. LinkedIn does not publish the number in its official help documentation, and a minority of sources claim 1,750. A comment longer than the cap will not post, so treat 1,250 as the working ceiling.
How long can a LinkedIn post be?
A LinkedIn post can be up to 3,000 characters including spaces, emoji, and line breaks. Only roughly the first 210 characters on desktop (about 140 on mobile) show before the "see more" cut, so the opening line carries most of the weight.
Does LinkedIn officially publish its character limits?
No. LinkedIn's help center does not maintain a public reference of character limits, which is why third-party numbers occasionally disagree. The figures in circulation come from tool makers and marketers testing the fields directly, and limits have changed over time without announcement. Any limits table needs a verified-as-of date.
Should a comment ever use all 1,250 characters?
Almost never. Comments longer than a few lines collapse behind a "see more" link, and most readers scroll past walls of text. We find comments in the 200 to 600 character range long enough to say something specific and short enough to be read in full.
What is the character limit for LinkedIn connection requests and messages?
A connection request note allows 300 characters, and a regular direct message to a connection allows 8,000. InMail is tighter, with a 200 character subject line and a body that most sources put between 1,900 and 2,000 characters.

The LinkedIn comment character limit is 1,250 characters. That is the number most independent sources report as of July 2026. LinkedIn does not document the limit anywhere in its help center, and a minority of sources say 1,750, so we cover the discrepancy below, along with every other LinkedIn character limit worth planning around.
Every number on this page was checked on July 19, 2026 against multiple independent references. Where they disagree, we say so, and we tell you which figure to budget for.
The LinkedIn comment character limit, verified
The LinkedIn comment character limit is the maximum text length LinkedIn accepts in a single comment on a post: 1,250 characters by the most widely reported count.
Three of the four references we checked while writing this page, Evaboot, Linked Helper, and AuthoredUp, list 1,250. One, Kondo, lists 1,750. We found no official LinkedIn help page stating either number, and that absence matters: every figure in circulation comes from people testing the field and publishing what they measured.
Our recommendation is boring on purpose: budget to 1,250. If the real ceiling turns out to be higher on some clients, you lose nothing by staying under the lower number. If you build a template around 1,750 and the lower figure is correct, your longest comments quietly fail to post.
Everything in the box counts against the cap: letters, spaces, punctuation, line breaks, emoji, and any URL you paste. Most people only discover the limit exists the day a long comment refuses to go through.
Every LinkedIn character limit in one table
Verified as of July 19, 2026, against the four sources cited under this article.
Two honest caveats. The post truncation points (roughly 210 on desktop, 140 on mobile) are approximations reported by AuthoredUp, not exact cutoffs; device, formatting, and line breaks all move where the fold lands. And these numbers have a shelf life. LinkedIn adjusts limits without announcements, which is exactly why this table carries a date.
Why sources disagree and LinkedIn stays silent
LinkedIn publishes no reference table for any of these limits. That single fact explains most of the confusion around the topic.
The numbers you find online come from tool makers and marketers pasting test strings into fields and recording where input stops. Those results get republished, then copied, then copied again. When LinkedIn changes a limit, the original tester might update their page, but the copies rarely follow, so stale figures circulate for years.
Counting methods add a second layer of noise. Some character counters treat emoji and other multi-byte characters differently than LinkedIn's own field does, so two people testing the same box can report different ceilings in good faith.
The practical takeaway: distrust any limits table without a date on it, and when two credible sources conflict, plan around the lower number. That rule costs you nothing and has never burned anyone.
What the comment limit means for how you write
Here is the part the limit tables skip: 1,250 characters is a ceiling, not a target.
A comment that long runs well past the point where LinkedIn collapses it behind a "see more" link, and comment sections are skimmed, not studied. In our experience reading thousands of comment threads while building Commenti (our product), the comments that earn replies and profile visits are specific and compact; the ones that approach the cap read like guest posts nobody asked for. We wrote up the reasoning in full in our guide to how long a LinkedIn comment should be, and you can see the shape of good ones in these LinkedIn comment examples.
That reading shaped a product decision: Commenti generates comments far below LinkedIn's ceiling by design, because the goal of a comment is a reply or a profile visit, and walls of text produce neither. One honesty note while we are here: Commenti automates commenting, and LinkedIn's User Agreement prohibits third-party automation, full stop. Our daily caps, human-like pacing, and skip filters exist to reduce that risk, not to remove it. We wrote about the tradeoff plainly in whether LinkedIn automation is safe.
The other caps that quietly shape results
A few of these limits do more work than they get credit for.
Headline, 220 characters. Everyone who hovers over your comment sees it. If you comment as a growth channel, this is your highest-traffic sentence, and most people waste it on a job title. Our LinkedIn commenting strategy covers how the headline converts comment readers into followers.
Connection request note, 300 characters. This is tighter than it feels. Draft to about 250 so a template with a merged first name never clips mid-sentence.
Post, 3,000 characters with a fold near 210. The limit is generous, but the fold is not. Whatever you need readers to know belongs in the first two lines, because that is all most of them see.
About section, 2,600 characters. Nobody reads it top to bottom. Front-load the one paragraph you would want a stranger to quote back at you.
Check the date before you trust the number
Every LinkedIn character limit on this page is a snapshot, verified July 19, 2026, from sources that measured the fields directly rather than from any official documentation, because none exists.
If you are reading this long after that date, spot-check the comment limit before wiring it into a template or a tool: draft a comment in a text editor, note the length, and see whether it posts. Five minutes of checking beats a month of comments silently cut short.
And once the ceiling is confirmed, remember that almost everything that makes a comment work happens in the first 200 characters. The limit is trivia; what you do inside it is the whole game.
