Count your LinkedIn post against the 3,000-character limit and ~140-character preview.
LinkedIn posts can be up to 3,000 characters, but the feed only shows about the first 140 before a “...see more” link. Getting a reader to click “see more” is a positive engagement signal, so your first two lines matter most. Paste your post to track both limits.
Below are LinkedIn's character limits across posts, headline, About section and more, with an example of sharpening an opening hook and answers to common questions.
| Field | Limit | Notes |
|---|---|---|
| Post / update | 3,000 characters | — |
| Feed preview | ~140 characters | After this, posts collapse behind “...see more”. |
| Headline | 220 characters | — |
| About / summary | 2,600 characters | — |
| Comment | 1,250 characters | — |
| Connection request note | 300 characters | — |
| Article body | ~110,000 characters | — |

Rewriting the first lines of a post so the hook lands before the “see more” cutoff.
I have been thinking a lot lately about the topic of career growth and over the past few weeks I came to a realization that I think is genuinely worth sharing with my network here today.
The best career advice I ever got fit in one sentence. It took me ten years to actually understand it. Here's what finally made it click ↓
A LinkedIn post (update) can be up to 3,000 characters. Only about the first 140 characters show in the feed before a “...see more” link appears.
Your LinkedIn headline can be up to 220 characters. It appears under your name across the platform, so it's prime keyword real estate.
The About (summary) section allows up to 2,600 characters. Only the first few lines show before a “...see more” link, so lead with your strongest summary.
A note attached to a connection request can be up to 300 characters, so keep your introduction brief and specific.
The feed truncates posts after roughly 140 characters. A strong hook in those first two lines earns the “see more” click, which signals engagement to LinkedIn's algorithm and can extend your reach.
