How to use the counter
- Pick the field: a post, a comment, your headline, your About section, a connection note, an InMail subject or body or a message.
- Paste or write your text. The count, what's left and the meter change as you type.
- If it runs over, the part past the limit shows under the meter, so you can see exactly what has to go.
- For a post, two previews show what readers see before "...see more", on a computer and on a phone.
What a good length looks like
- Room to spare. A post at 2,998 characters has no space for the line you think of after posting.
- The point before the fold. A phone shows about 140 characters before "...see more", so the reason to keep reading goes there.
- A note that fits 200. It works on every account, with Premium or without.
- A headline that works in its first 60 to 70 characters. That is about how much shows in search results, invitations and comments, as AuthoredUp reports it.
- Messages well under their limit. 8,000 characters is room, not a target. A first message that fits on a phone screen is easier to read and answer.
LinkedIn character limits, field by field
| Field | Limit | Where it comes from |
|---|---|---|
| Post | 3,000 | LinkedIn Help, "Post and share updates" |
| Comment | 1,250 | LinkedIn Help's limits for groups, for comments in groups; AuthoredUp (August 2026), for comments on posts |
| Headline | 220 | Buffer's headline generator and AuthoredUp (August 2026) |
| About section | 2,600 | LinkedIn Talent Blog, April 2024 |
| Connection note | 200 or 300 with Premium | LinkedIn Help, "Personalize invitations to connect" (200); an older LinkedIn Help page on InMail and invitations (300 with Premium) |
| InMail subject | 200 | LinkedIn Help, "Send an InMail message" |
| InMail body | 2,000 with Premium; 1,900 in Sales Navigator and Recruiter | LinkedIn Help, "Send an InMail message"; "Send an InMail message in Sales Navigator"; "InMail character limits" |
| Message | 8,000 | AuthoredUp (August 2026) |
| "...see more" in a post | About 210 on a computer, 140 on a phone | AuthoredUp (August 2026). LinkedIn doesn't publish it. |
Without Premium, LinkedIn Help says you can add a note to up to three invitations a month. In Sales Navigator, a signature of up to 150 characters counts toward the 1,900.
Tips for writing to a limit
- Write long, then cut. The box under the meter shows exactly what runs past the limit.
- Cut padding before meaning. "I just wanted to reach out to" is six words that say nothing.
- Count your line breaks. Each one is a character, so a post of many short lines uses more of the 3,000 than it looks.
- Over 3,000? Write an article. LinkedIn Help suggests an article for anything longer than a post can hold.
Questions
What is the character limit for a LinkedIn post?
3,000 characters, according to LinkedIn Help. About the first 210 show on a computer and 140 on a phone before "...see more", as AuthoredUp reports.
How long can a LinkedIn comment be?
1,250 characters. LinkedIn Help gives that figure for comments in groups and AuthoredUp reports the same for comments on posts.
How long can a connection note be?
LinkedIn Help's page on personalizing invitations says 200 characters and an older LinkedIn Help page gives Premium members 300. A note that fits 200 works on every account.
What are the limits for an InMail?
200 characters for the subject. For the body, LinkedIn Help gives 2,000 for Premium InMail and 1,900 in Sales Navigator and Recruiter.
Does an emoji count as one character?
The counter counts most emoji as two, since each is stored as two units of text. Counted that way, text it passes fits LinkedIn's limit whichever way LinkedIn counts.
Does the counter send my text anywhere?
No. It runs in your browser and nothing you type leaves this page.

Where FOUND fits
Counting is the easy part of outreach. Knowing who to write to and what to say to each person, is the work. FOUND, an AI SDR for LinkedIn, does that work: it watches for buying signals every day, checks each person against your buyer and writes the connection note (on a Premium account), the messages and the emails from what that person did, with each lead's verified work email found for you. Review mode holds every one until you approve it.
Watch it in the demo or see the pricing: $69 a month for two agents, one LinkedIn account, one mailbox and 100 credits.
