LinkedIn character counter

Every LinkedIn character limit, with its source

Read from LinkedIn's help pages on 2026-09-03. Verified means LinkedIn states the figure and its pages agree. Where LinkedIn pages disagree, both figures are shown. Where LinkedIn publishes nothing, the row says so and gives the widely reported figure as unverified.

What each LinkedIn page says

Connection request note (free account): 200

Both LinkedIn pages that state a figure agree on 200 characters for a free account. They disagree on how many personalised notes a free account gets each month: the current page says three, the two older pages say five.

• “Each message can be up to 200 characters”

  LinkedIn help a563153. Current page (about four months old at fetch). It also says free accounts get three personalised requests a month, and that Premium members get unlimited personalised invitations, with no Premium character count.

• “Members with basic (free) accounts can send up to five personalized invitations to connect with a character limit of 200.”

  LinkedIn help a6239760. Older page (about two years old at fetch). Agrees on 200 but says five personalised invitations a month, not three.

• “Basic and free LinkedIn members can include a personalized message to five connection requests per month.”

  LinkedIn help a550555. Also says five a month. Gives no character count.

Connection request note (Premium): 300 (older page only)

The 300 figure comes from one older LinkedIn page only. The current page on personalised invitations gives no character count for Premium, so treat 300 as unconfirmed by LinkedIn's current documentation.

• “Members with Premium memberships are able to send an unlimited number of personalized notes with their invitation/connection requests each with a character limit of 300.”

  LinkedIn help a6239760. Older page (about two years old at fetch). The only LinkedIn page that gives a Premium character count.

• “LinkedIn Premium members can send unlimited personalized invitations to all their connection requests (connection request limits may still apply)”

  LinkedIn help a563153. Current page. Gives no Premium character count at all.

Post: 3,000

Two LinkedIn pages agree on 3,000. Where the "see more" fold falls is not documented by LinkedIn; the figures you see elsewhere (around 210 characters or three lines on desktop) are third-party measurements.

• “The character limit for a post is 3,000 characters.”

  LinkedIn help a528176. Updated about a week before fetch. The same page: "If your post exceeds 3000 characters, you can instead write an article using LinkedIn's Publishing Platform."

• “The character limit for a post is 3000 characters.”

Profile headline: Not published. Reported: 220 (unverified)

LinkedIn's help page on the headline gives no character count. 220 is the figure widely reported by third parties (raised from 120 in late 2024, by those reports). LinkedIn does not state it.

Checked LinkedIn help a542926: "Edit Your Headline": describes how to edit the headline and gives no character count.

About section: Not published. Reported: 2,600 (unverified)

LinkedIn's help page on the About section gives no character count. 2,600 is the figure widely reported by third parties. LinkedIn does not state it.

Checked LinkedIn help a553140: "Edit the About section on your profile": describes how to edit the section and gives no character count.

Comment on a post: Not published. Reported: 1,250 (unverified)

LinkedIn publishes 1,250 for comments in groups only. No LinkedIn page states a limit for comments on feed posts; the 1,250 figure repeated for feed comments is unverified.

• “Character limit for comments 1250”

  LinkedIn help a544801. This is the Groups limits table. It applies to comments in groups, not to comments on feed posts.

Checked LinkedIn help a524166: "Comment on posts and reply to a comment": describes how to comment and gives no character count.

InMail subject line: 200

Every LinkedIn page that states a figure says 200 for the subject line. The pages disagree on whether the subject line is required or optional.

• “InMail messages can have up to 200 characters in the optional subject line and up to 2000 characters in the body.”

  LinkedIn help a554514. InMail FAQ, updated three days before fetch.

• “InMail messages can have up to 200 characters in the required subject line and up to 1900 characters in the body.”

  LinkedIn help a411986. InMail character limits page. Identical copies at /help/recruiter/answer/a411986 and /help/sales-navigator/answer/a411986.

InMail body: 1,900 or 2,000

LinkedIn contradicts itself. Three pages say 1,900 (the InMail character limits page, the Sales Navigator compose page and the Recruiter InMail FAQ). Two say 2,000 (the InMail FAQ and the send-InMail page). The tool counts against 1,900, the lower figure. In Sales Navigator a signature of up to 150 characters counts toward the total.

• “InMail messages can have up to 200 characters in the required subject line and up to 1900 characters in the body.”

  LinkedIn help a411986. InMail character limits page. Identical copies at /help/recruiter/answer/a411986 and /help/sales-navigator/answer/a411986.

• “Add a subject line (200 character limit) and enter your message (1900 character limit).”

  Sales Navigator help a107018. Sales Navigator compose page. The same page: "Signatures are limited to 150 characters, which are counted in the total number of message characters."

• “Subject line: up to 200 characters Message body: up to 1,900 characters”

A separate LinkedIn page on writing articles says there is no limit on word count; the character limit is the one LinkedIn states.

• “Articles are typically longer than posts and are limited to 125,000 characters.”

  LinkedIn help a522483

Custom profile URL: 3 to 100

The part after linkedin.com/in/. Between 3 and 100 characters, letters and numbers only.

  LinkedIn help a542685

Skills on a profile: 100 skills

A count of skills, not characters. LinkedIn publishes no per-skill character limit.

• “You can add up to 100 skills to your profile.”
