LinkedIn post, headline, comment, article, and connection-request character counter with LinkedIn-style preview, "see more" cutoff indicator, and headline strength score.
A free LinkedIn character counter covering 10 LinkedIn fields with their exact 2024 limits — Headline (220), About (2,600), Post (3,000), Comment (1,250), Connection request (300), Article (110,000), Job description (25,000), Recommendation (3,000), Tagline (120), Experience (2,000). LinkedIn-style preview card mimics the actual feed look (Inter font, LinkedIn blue #0a66c2, profile photo placeholder, 1m timestamp), with the "see more" truncation line at ~210 chars / 3 lines so you can see exactly what the feed will show. Headline tab includes a 5-point Strength score, and templates for headlines, posts, and connection notes.
LinkedIn's feed isn't purely chronological. Posts go through a "dwell time" test in the first 1-2 hours: the algorithm shows your post to ~5% of your network, measures how long they spend reading and whether they engage (like, comment, share). High dwell time + high engagement = wider distribution. Low dwell time = the post stops there. The implications for writing: hook hard in the first 3 lines (above the "see more" cut), break paragraphs short (white space in the feed reads better), use line breaks generously, end with a question to drive comments. Single long paragraphs lose readers fast.
The acceptance rate for connection requests on LinkedIn is roughly 30% for cold outreach, but well-crafted notes lift that to 60-70%. The structure that works: Line 1: how you found them (mutual connection, conference, content). Line 2: specific reason for connecting (their work on X, your shared interest in Y). Line 3: low-pressure call to action ("would love to learn more about your approach to X"). Sign off. Avoid: pitching a product, asking for time on a call, mentioning your services. Connection requests are about getting in the door; the conversation happens after acceptance.
LinkedIn raised the headline limit from 120 to 220 characters in early 2024. Most feed and search displays still truncate around 120-150 chars, so the first 120 must contain the most important keywords and value proposition. Use the next 100 chars to add personality, secondary credentials, or a hook. The Headline Strength score in this tool checks for role mention, industry keyword, company mention, personality hook, and 220-char compliance.
LinkedIn truncates posts in the feed at approximately 210 characters or 3 lines, whichever comes first. The "see more" indicator in this tool shows that cutoff line so you can position your hook above it. Posts that hook readers in the first 3 lines get clicked open and read fully; posts where the value lives below the fold get scrolled past.
For maximum reach, 1,200-1,500 characters is the sweet spot — long enough to deliver genuine value, short enough to read in 30 seconds. The very short (under 200 chars) and very long (over 2,500 chars) posts get fewer views statistically. The hook (first 3 lines, ~210 chars) is the most important — that's what determines whether the reader clicks "see more" and engages with the rest.
LinkedIn caps connection request notes at 300 characters specifically because they want to discourage long sales pitches in connection requests. The 300-char limit forces brevity: introduce yourself, mention shared context, propose a clear next step, sign off. Your goal is to get them to accept; the actual conversation happens after they accept and reply. Templates in this tool provide proven 250-char request structures.
The score checks 5 criteria: (1) mentions a role / job title, (2) includes an industry keyword, (3) mentions a current or past company (Senior X at Y, Ex-Y), (4) has a personality hook ("Helping X achieve Y", "Building X for Y"), (5) under 220 chars. Each pass adds 1 point, max 5. A score of 4-5 typically lands in the "found by recruiters" zone; 1-2 means your headline reads as generic and may underperform in LinkedIn search.
