The short answer

Posts: 3,000 characters. Comments: 1,250. Headline: 220.

A LinkedIn post can hold 3,000 characters, on a personal profile and on a company Page. The feed folds it behind "more" after about 150 characters, the length LinkedIn's ad specs say avoids truncation. LinkedIn does not publish the cut for posts, and line breaks can bring it sooner, so put the point first.

Comments take 1,250 characters and headlines 220, the figures most guides give, though LinkedIn's Help Center does not state them. If a post runs past 3,000 characters, LinkedIn suggests writing an article instead.

App vs schedulers

What a scheduled post must fit. Schedulers publish through LinkedIn's Posts API.

Every scheduler, OmniSocials included, posts through LinkedIn's API. OmniSocials holds profile and Page posts to 3,000 characters and first comments to 1,250, and escapes brackets and parentheses so posts keep their text.
Tips

Write posts that get read. The fold decides.

  1. Put the point in the first line

    The feed shows about 150 characters. Say what the post is about there; the rest is for people who tap "more".

  2. Break long posts into short lines

    Short paragraphs read better past the fold. The counter's copy button keeps blank lines with an invisible character.

  3. Write an article past 3,000

    LinkedIn's Help Center points longer posts to its publishing platform. Share the article in a short post.

  4. Headline: role and value

    220 characters is room for what you do and who you help. Put the most important words first.

  5. Keep poll options short

    Options stop at 30 characters and questions at 140. A schedulable poll takes 2 to 4 options.

  6. Add alt text to images

    Alt text describes an image for screen readers. LinkedIn's API takes up to 4,086 characters and recommends under 120.

How we built this guide. Checked on October 17, 2026.

Each limit comes from LinkedIn's Help Center or Microsoft's LinkedIn API reference, read on October 17, 2026. Where LinkedIn publishes no number but guides agree (comments, headline, About), the table shows the figure and says it is not official. Where guides disagree (messages, connection notes, articles), it says "Not published". The 150-character fold comes from LinkedIn's ad specs, not a post rule.
