What Is the Character Limit for LinkedIn Posts?
Founder of ContentIn — I've built LinkedIn tools since 2023 and test every competitor with a real account.
Key Takeaways
- A LinkedIn text post is capped at 3,000 characters, counting spaces, emojis, and line breaks.
- Comments cap at 1,250 characters; the profile headline at 220; the About section at 2,600.
- A published LinkedIn article can run to roughly 110,000 characters — the platform's longest-form field.
- Only the first ~140 characters (mobile) or ~210 (desktop) of a post show before the 'see more' fold, so the practical limit for attention is far shorter than the technical one.
- Limits are enforced in the composer: hitting the cap simply stops further typing, with no penalty.
How LinkedIn Character Limits Work
A character limit is the maximum number of characters LinkedIn accepts in a specific field — a post, a comment, your headline, and so on. The count includes everything: letters, spaces, punctuation, emojis, and line breaks. Limits are enforced in the composer, so when you reach the cap the field stops accepting new characters. There is no penalty for hitting it; you simply cannot type past it.
The limits differ sharply by field because each field does a different job. A post is built for a single idea and caps at 3,000 characters.[1]LinkedIn Help. "Post and share updates."

Your headline is a one-line label that appears next to your name everywhere on the platform, so it is tight at 220 characters.[2]LinkedIn Help. "Edit Your Headline."

One number matters more than any of these: how much of a post shows before the "see more" fold. LinkedIn truncates a feed post after roughly 140 characters on mobile and 210 on desktop. So while the post limit is 3,000, the limit that governs whether anyone reads you is closer to 200 — which is why the hook carries so much weight.
LinkedIn Character Limits by Field
Current limits for the fields creators use most (each counts spaces and emojis):
| Field | Character limit | Notes |
|---|---|---|
| Text post / update | 3,000[1]LinkedIn Help. "Post and share updates." View source | Only ~140–210 show before "see more" |
| Comment | 1,250 | Applies to post comments and replies |
| Headline | 220[2]LinkedIn Help. "Edit Your Headline." View source | Shown beside your name platform-wide |
| About (summary) | 2,600[3]LinkedIn Help. "Edit the About section on your profile." View source | Truncates after ~3 lines until "see more" |
| Article title | 100 | The headline of a published article |
| Article body | 110,000[4]LinkedIn Help. "Write and publish articles on LinkedIn." View source | LinkedIn's longest-form field |
These are product-enforced maximums and can change without notice; when precision matters, count against them with a character counter before you publish.
Example of a Character Limit in Practice
Say you draft a post that runs 3,180 characters. The composer accepts the first 3,000 and refuses the rest, so the final 180 characters — often your call to action — disappear. Now flip the problem: a 2,400-character post sits well under the cap, but only the first ~140 characters appear in the mobile feed. If your key point lands at character 900, most readers never reach it. Both failures come from ignoring a limit — one technical, one practical. The fix for the first is trimming; the fix for the second is moving your strongest line to the top.
The Bottom Line
LinkedIn's character limits are 3,000 for a post, 1,250 for a comment, 220 for the headline, 2,600 for the About section, and roughly 110,000 for an article. Every limit counts spaces and emojis and stops you at the cap. But the number that decides whether your writing gets read is none of these — it is the ~200 characters shown before the fold. Write to the fold first and the field limit second, and consider a readability score check so the words that do show are easy to scan.
What people get wrong about LinkedIn's character limits
People treat 3,000 characters as a target instead of a ceiling. It isn't a word count to fill — it's the outer wall of a room you almost never need. The limit that actually rules your reach is the ~200 characters before the 'see more' fold, and the field you should obsess over is not the post at all: it's the 220-character headline, which follows you into every feed, comment, and search result you appear in, working even when you aren't posting. Maxing out the post while phoning in the headline is the most common way creators waste the limits LinkedIn gives them.
| Character Limit | Line Break Formatting | |
|---|---|---|
| What it caps | Total characters you can type in a field | How much text shows before 'see more' truncates |
| For a post | 3,000 characters | ~140 (mobile) / ~210 (desktop) visible |
| Set by | LinkedIn's field maximum | The feed's truncation point |
| You hit it when | The composer stops accepting text | The reader has to tap to see the rest |
Frequently Asked Questions
- What is the character limit for a LinkedIn post?
- 3,000 characters, including spaces, emojis, and line breaks. It applies to text posts and to the caption on image and video posts. The composer stops accepting input once you reach 3,000.
- How many characters can a LinkedIn comment be?
- 1,250 characters. The same limit applies to top-level comments and to replies. Long comments truncate with a 'see more' link, just as posts do in the feed.
- What is the LinkedIn headline character limit?
- 220 characters. Your headline sits under your name across the platform — in the feed, in comments, and in search — so those 220 characters are among the most valuable on your profile.
- Do spaces and emojis count toward the limit?
- Yes. Every character counts: letters, spaces, punctuation, line breaks, and emojis. A single emoji can consume one or more characters depending on how it is encoded, so verify with a counter if you are close to the cap.
- How long can a LinkedIn article be?
- Up to roughly 110,000 characters in the body, with about 100 characters for the title. Articles are LinkedIn's long-form format and vastly exceed the 3,000-character post limit.
