LinkedIn Character Counter

The LinkedIn character counter is a free live tool that measures your text against every LinkedIn limit in real time. Paste a post, a headline, an About summary, an experience bullet, a company page description, an article, a comment, an InMail, or an ad headline, and you will instantly see how many characters you have used, how many remain, and whether you are about to be cut off. LinkedIn enforces different caps on every surface, and each cap behaves differently in the feed, on profile pages, and inside paid campaigns. A dedicated LinkedIn character count tool saves you from silent truncation and from publishing text that looks trimmed on mobile.

Most writers lose readers not because their idea is weak but because the first line was buried under a “see more” truncation, the headline was cut mid-word on a search card, or the About section hit the wall at 2,600 characters and ended with a comma. This counter fixes that in one pane. Keep it open in a tab while you draft, and you will never publish a post that breaks at the wrong place again.

LinkedIn character limits by surface

LinkedIn maintains separate character limits for every field and post type. Use the sections below as a quick reference, then paste your draft into the counter above to validate it live.

LinkedIn post character limit: 3,000

A standard LinkedIn feed post supports up to 3,000 characters, including spaces, line breaks, hashtags, and emoji. The first 210 characters are the only ones visible in the desktop feed before the “see more” link appears; on mobile the preview is even shorter. Treat those first lines as your headline, not your introduction.

LinkedIn headline character limit: 220

Your profile headline caps at 220 characters. The headline is indexed for LinkedIn search, appears beside every comment you leave, and shows under your name on every connection request. Use the full length to stack a role, a specialization, and a proof point separated by pipes or bullets.

About section character limit: 2,600

The About summary on a personal profile accepts 2,600 characters. Only the first three lines (roughly 220 to 370 characters depending on device) render before the “see more” fold. Front-load a hook, then expand into credentials, philosophy, and a call to action.

Experience description character limit: 2,000

Each role in the Experience section allows 2,000 characters. This is enough to describe scope, stack, metrics, and outcomes without padding. Recruiters skim, so structure each role with short paragraphs and bulleted wins rather than one dense block.

Company page description character limit: 2,000

A LinkedIn company page “About” description accepts 2,000 characters. The first 156 characters also appear as the meta description in search engines, so write that opening as if it were a landing page tagline.

LinkedIn article character limit: 110,000

Long-form articles published through LinkedIn support up to 110,000 characters, roughly 15,000 to 20,000 words. Practically, articles that perform sit between 1,000 and 2,000 words. Use the counter to monitor pacing and keep sections scannable.

LinkedIn comment character limit: 1,250

Comments on posts and articles accept 1,250 characters. Thoughtful comments are one of the fastest ways to grow reach on LinkedIn, and the counter helps you stay inside the limit while still adding substance.

InMail character limit

Sponsored InMail and Recruiter InMail enforce a 200-character subject line and a 2,000-character body. The counter flags both so your outreach lands in full rather than being trimmed on the recipient’s preview pane.

LinkedIn ad copy character limit

Single Image Ads allow an introductory text of 600 characters and a headline of 150 characters. Message Ads use a 60-character subject and a 1,500-character body. Dynamic Ads cap headlines at 50 characters. Pick the format from the counter and write inside the right window the first time.

How to use the LinkedIn character counter

• Open the counter and select the LinkedIn surface you are writing for.
• Paste or type your draft into the text area. The character count, word count, and remaining characters update on every keystroke.
• Watch the truncation marker at 210 characters for feed posts. Anything before that marker is what scrolling readers will see.
• Adjust wording until the counter is green and the preview reads well at the fold.
• Copy the approved text back into LinkedIn and publish.

Use cases

• Creator posts. Craft hooks that fit inside the 210-character preview and still leave room for a full 3,000-character story underneath.
• Recruiting headlines. Hiring managers and recruiters use the 220-character headline to stack role, stack, and availability signals that LinkedIn search can index.
• About sections for job seekers. Use the full 2,600 characters to tell a career narrative, then verify the first three lines convince a recruiter to expand.
• Company pages. Marketing teams tighten the 2,000-character company description so the opening 156 characters work as an SEO meta description.
• Newsletters and articles. Newsletter editors check article length before publishing to keep reading time around six to eight minutes, the sweet spot for LinkedIn long-form.
• Sales and outreach. SDRs validate InMail subject lines and bodies so messages are not cut off on mobile inboxes.
• Paid campaigns. Performance marketers check each ad variant against the exact limit for the format before uploading to Campaign Manager.

Best practices for writing inside LinkedIn limits

• Treat the first 210 characters as a headline. The “see more” truncation in the feed sits around 210 characters on desktop. If your hook is not resolved before that line, most readers will scroll past.
• Write the headline for search as well as humans. LinkedIn indexes the 220-character headline for profile discovery. Include the role, the specialization, and the audience you serve so the right people find you.
• Open the About section with a three-line hook. Only the first three lines are visible before the fold on a profile, so lead with a promise, a question, or a credential.
• Leave breathing room. Do not fill every field to the last character. Short white-space lines increase readability and keep posts from looking like walls of text on mobile.
• Put the link below the fold on feed posts. LinkedIn deprioritizes posts with links in the first lines. Drop the URL in the comments or below the fold.
• Use line breaks instead of long sentences. A line break every one to two sentences doubles perceived readability in the feed.
• Audit every role for the 2,000-character cap. If an experience entry is trimmed mid-bullet, recruiters see a broken paragraph on your profile.
• Validate ad copy twice. Campaign Manager accepts text right up to the cap, but long ad headlines wrap and lose impact. Aim for 70 to 90 percent of the limit.
