What is a good length for a LinkedIn post?

LinkedIn allows up to 3,000 characters. Most readable posts fall well under that, often between a few hundred and about 1,500 characters. Length matters less than structure: short paragraphs, a clear first line, and one main idea.

How long should the first line of a LinkedIn post be?

Keep it under about 80 characters and follow it with a line break. On mobile, LinkedIn shows only about 140 characters before "…see more", so the first line needs to be a complete thought.

How many hashtags should I use on LinkedIn?

Hashtags are optional. If you use them, 3 to 5 relevant hashtags is a common choice. Keep them in plain text, because bold or italic hashtags stop working as hashtags.

Does this tool predict how many views my post will get?

No. Reach depends on your network, timing, and how people engage, which no text checker can know. The analyzer checks structure and readability, which make a post easier to read once people see it.

What is a reading ease score?

It is the Flesch reading ease score, calculated from average sentence length and syllables per word. Scores run from 0 to 100, and higher is easier. 60 or above reads comfortably for most adults.

Does bold or italic text hurt readability?

A few styled words help readers find the key point. Large amounts of styled text are harder to read, can be read out letter by letter by screen readers, and may not match in LinkedIn search.

Does it work for LinkedIn comments and articles?

It is designed for feed posts, but the length, readability, and paragraph checks are useful for comments and article sections too.

Free LinkedIn Post Analyzer: Check Your Hook, Length & Readability

How to check a LinkedIn post before you publish

Paste your draft. Paste your LinkedIn post into the analyzer. The score and checks update as you type.
Read the checks. Start with anything marked "Needs fixing", then "Could improve". Each check explains what it found and how to fix it.
Edit and re-check. Make the changes in the analyzer, watch the score update, then copy your post into LinkedIn or open it in the formatter to add styling.

How the score works

The score runs from 0 to 100. Each check passes, could improve, or needs fixing, and some checks count for more than others. The hook checks carry the most weight, because they decide whether people read the rest. Notes, such as a link in your post, are shown but not scored.

Post length

LinkedIn posts can be up to 3,000 characters. Posts under 100 characters often lack context. Posts over about 1,800 characters need strong structure to hold attention.

Hook length

The first line does the most work. Lines under about 80 characters can be read at a glance in the feed.

Hook before "…see more"

LinkedIn shows roughly the first 200 characters or 3 lines on desktop, and about 140 characters on mobile. If your first line is cut off, readers have to guess what the post is about.

Paragraph length and white space

Most people read LinkedIn on a phone. Paragraphs over 300 characters or 4 lines look like a wall of text on a small screen. Blank lines between ideas make posts easier to scan.

Readability

The analyzer calculates a Flesch reading ease score from sentence length and syllables per word. 60 or above is easy for most readers. Below 30 is hard going.

Hashtags

Hashtags are optional. If you use them, a focused set of 3 to 5 relevant tags looks cleaner than a long list.

Bold and italic text

LinkedIn bold and italic text is made from Unicode look-alike letters. Screen readers can struggle with them, and styled hashtags stop working as hashtags. Use them for a few key words only.

Emoji

Emoji work well as signposts, such as one per list item. More than about one emoji for every 7 words starts to distract from the message.

Ending

Posts that end with a question or a clear next step tell readers how to respond. Hashtag lines at the end are ignored for this check.

What makes a LinkedIn post easy to read

One idea per post, stated in the first line.
Short paragraphs of 1 to 3 sentences, with blank lines between them.
Lists for steps, tips, or anything with three or more points.
Plain words and short sentences. Save jargon for when it is the clearest option.
A closing question or next step, so readers know how to respond.
