LinkedIn Post Character Limit: 3,000 — and the Number That Matters More

A LinkedIn feed post accepts 3,000 characters. That is the hard ceiling, and hitting it returns an error rather than truncating your text. The number that actually shapes your writing is much smaller: only roughly 140 to 250 characters appear before the See more link, so everything past the first two or three lines is opt-in reading.

#Quick answer

• Post limit: 3,000 characters.
• Visible before "See more": roughly 140–210 on mobile, around 200–250 on desktop.
• Comment limit: 1,250 characters, shown in full with no fold.
• Does it count spaces? Yes. Spaces, line breaks and emoji all count.
• What happens if I exceed it? LinkedIn rejects the post. It does not silently cut it.

#The fold is the real constraint

Your first two lines decide whether anyone reads the other 2,900 characters. Everything after See more is hidden behind a click that most people never make.

The exact cutoff is not a fixed number LinkedIn publishes, and reported figures differ because it depends on screen width, font size and where your line breaks fall. Treat it as a range, not a spec: assume around 140 characters on mobile and plan your opening to work inside that. If your hook needs 200 characters to land, it will land for desktop readers and get cut for everyone else.

Practical consequence: put the point first. A post that opens with context and reveals the point in paragraph three is a post with a hidden point.

#Every LinkedIn limit worth knowing

Images and video cannot be mixed in the same LinkedIn post. Two or more images become a swipeable carousel automatically; a PDF becomes a document post, which is a different format again — covered here.

#How LinkedIn compares to other networks

Worth knowing if you write once and post in several places:

Two of these are not as simple as the number suggests. Bluesky counts graphemes rather than characters, so an emoji made of several code points still costs one. Mastodon's 500 is only the default — individual servers routinely raise it to 5,000, so the real limit depends on which instance your account lives on.

Schedule & Chill posts to LinkedIn, Bluesky, Mastodon and YouTube today, and counts each platform's limit separately as you type rather than applying one shared count.

#Writing to the limit without writing to the limit

• Front-load the hook. First 140 characters carry the whole post.
• Break lines early. A wall of text loses readers before the fold does.
• Do not pad to 3,000. Length is not a ranking signal; finishing the thought is.
• Watch emoji. They count, and on some platforms they count as more than one.
• Put links in a comment if you like — LinkedIn allows a first comment on personal profile posts, though not on Page posts.

#Frequently Asked Questions

What is the character limit for a LinkedIn post? 3,000 characters, including spaces, line breaks and emoji. Exceeding it stops the post from publishing rather than truncating it.

How many characters show before "See more" on LinkedIn? Roughly 140 to 210 on mobile and around 200 to 250 on desktop. It varies with screen width and line breaks, so treat it as a range and write your hook to fit the smaller end.

What is the LinkedIn comment character limit? 1,250 characters, and comments display in full without a "See more" fold.

Do spaces and emoji count toward the LinkedIn character limit? Yes, all of them. On Bluesky an emoji counts as a single grapheme, but on LinkedIn every character in the string counts.

How many images can I put in one LinkedIn post? Nine. Two or more become a swipeable carousel. You cannot mix images and video in the same post.

What is the ideal LinkedIn post length? There is no single answer that survives checking, and published "ideal lengths" contradict each other. The reliable rule is narrower: make the first 140 characters do real work, and stop when the thought is finished.
