Free LinkedIn Character Counter
Count characters against the real limit for every LinkedIn field — post, headline, About, comment, connection note and more. Live count, over-limit warning, and the “…see more” hook preview. No sign-up.
Posts of 1,300–2,500 characters tend to earn the most engagement. Lead with a strong hook — only the first ~210 characters show before “…see more”.
Start typing to see your hook.
How to Use the LinkedIn Character Counter
Count against the right limit in 3 steps.
Pick your field
Choose the LinkedIn field you're writing — Post, Headline, About, Comment, and more. Each has its own real character limit.
Type or paste
Your character count updates live against that field's limit, with a gauge that turns amber near the limit and red when you go over.
Nail the hook
For posts and your About section, see exactly what shows before “…see more” so your first line earns the click.
LinkedIn Character Limits: Every Field (2026)
LinkedIn caps almost every field, and going over means your text gets cut off — or won't post at all. Here are the current character limits for every LinkedIn field, and where each one truncates with “…see more”.
| LinkedIn field | Character limit |
|---|---|
| Post | 3,000 |
| Headline | 220 |
| About / Summary | 2,600 |
| Comment | 1,250 |
| Connection request note | 300 |
| Direct message | 8,000 |
| InMail subject | 200 |
| InMail body | 2,000 |
| Company tagline | 120 |
| Company description | 2,000 |
| Experience description | 2,000 |
| Article title | 150 |
| Recommendation | 3,000 |
| Poll question | 140 |
| Poll option | 30 |
LinkedIn post character limit
A LinkedIn post can be up to 3,000 characters. Only about the first 210 characters show on desktop (and ~140 on mobile) before the “…see more” cut — so your hook lives in that opening line. Posts of 1,300–2,500 characters tend to earn the most engagement.
LinkedIn headline character limit
Your headline can be up to 220 characters, but only ~60–70 show in search results and previews — front-load your role and value proposition.
LinkedIn About section character limit
The About / Summary section allows 2,600 characters, with only ~300 shown before “…see more.” Lead with your strongest line so people keep reading.
Comments, connection notes & messages
Comments allow 1,250 characters (shown in full), a connection request note allows 300, and a direct message allows 8,000. Company taglines are capped at just 120.

How is a character counted — do emojis count as one?
We count Unicode characters, so an emoji counts as one character (matching how LinkedIn's limit behaves for most emoji). Spaces and line breaks count too.
