LinkedIn Character Counter
Stay within every LinkedIn character limit: posts (3,000), headlines (220), about section (2,600), comments (1,250), and InMail subject (200). Live count, see-more preview, and warning when you cross each limit. Runs in your browser.
How to use the LinkedIn character counter
1. Pick your target surface
LinkedIn has different character limits for different fields. The Surface selector switches the target between post (3,000), headline (220), about section (2,600), comment (1,250), InMail subject (200), and company tagline (120). The live counter updates instantly when you switch.
2. Type or paste your draft
The Draft box on the left accepts free-form text. The right side updates in real time with current count, word count, hashtags, @ mentions, and a read time estimate. A warning appears when you cross the selected limit.
3. Use the feed preview to craft your hook
For post drafts, the Feed preview shows where the see-more cutoff lands on desktop (approximately 210 characters) and mobile (approximately 140 characters). The first 140 characters are what people see in their feed before clicking. Make sure your hook is in there.
4. Copy when ready
Click Copy to grab the draft and paste it into LinkedIn. Your draft auto-saves to browser local storage; clear it with Clear draft when done.

What drives LinkedIn engagement
LinkedIn feed algorithm rewards dwell time, comments, and reshares. Posts that get long-form comments outperform posts that get likes alone. This pushes copy toward mid-length (1,200-1,500 characters): long enough to make a substantive point, short enough that readers finish. Posts that exceed 2,000 characters are read less completely, which depresses the dwell-time signal. See also: Hashtag Counter.
The first 140-210 characters are the hook. They are the only thing most feed scrollers see before deciding to expand or scroll past. Putting the punchline in the first sentence (an unexpected stat, a contrarian claim, a personal anecdote) is the highest-leverage edit you can make on a draft. The feed preview pane in this tool shows exactly where that cutoff lands.
Hashtags and @ mentions count toward the character total. Three hashtags is the LinkedIn-recommended sweet spot; more than five reads as keyword stuffing to readers and (according to some practitioner reports) to the algorithm. Mentions can drive comment notifications, but only when the mentioned person actually responds.

Frequently asked questions
What are the LinkedIn character limits?
Post (feed update): 3,000 characters. Headline (under your name): 220 characters. About section (summary): 2,600 characters. Comment: 1,250 characters. InMail subject: 200 characters. Article: 110,000 characters (rarely a limit). Company page tagline: 120 characters.
When does the "see more" cutoff appear in a post?
On desktop the feed truncates a post at approximately 210 characters with a "see more" link. On mobile the cutoff is around 140 characters. The exact number varies with line breaks and emoji. The Visual preview pane shows where the see-more cutoff lands so you can craft the hook in the first 140-210 characters.
Do hashtags count toward the post character limit?
Yes. Hashtags (#word) and mentions (@name) count toward the 3,000-character limit just like regular text. The tool counts them separately so you can see how much of your budget they consume.
Does emoji use double characters like Twitter?
LinkedIn counts most emoji as one character, regardless of byte length. Some compound emoji (skin-tone variants, family combos) are counted as multiple code points by LinkedIn server-side; the tool shows the grapheme-cluster count which is the visual character count most authors expect.
What is the optimal post length?
LinkedIn engagement research consistently shows that mid-length posts (1,200-1,500 characters) outperform very short or very long posts. Posts under 200 characters can struggle to drive engagement; posts over 2,000 are read less completely. The tool flags Below recommended and Above recommended ranges as visual indicators, not hard rules.
Headlines vs job titles, which limit is 220?
The 220-character limit is the field under your profile name (the editable "headline"). The "Current position" job title in the experience section has its own field. Most people use the headline for a value-prop tagline, not a literal job title.
Can I save my draft?
The tool keeps your draft in browser local storage automatically. Closing the tab and reopening it restores the last draft. Clear Draft removes the local copy. The draft never leaves your device.
Is my text uploaded anywhere?
No. Counting runs in client-side JavaScript. The draft you type stays in your browser tab and (optionally) your browser local storage. We have no upload endpoint and we do not log content. See also: Facebook Character Counter.
