What are the LinkedIn character limits in 2026?
Post 3,000, headline 220, About 2,600, connection note 300, comment 1,250, InMail subject 200, InMail body 2,000, and direct message 8,000 characters. The feed truncates posts at roughly 210 characters with a see-more link, so front-load your hook. Use the live counters below to check any field against its limit.
How this is calculated
Limits were web-verified in 2026 and corroborated across multiple sources. Counts include spaces, emojis, and line breaks, the same way LinkedIn counts them.
The see-more cut-off (about 210 characters on desktop) is a visibility threshold, not a hard limit, and it varies by device and line breaks.

Frequently asked questions
What are the LinkedIn character limits in 2026?
Post 3,000, headline 220, About section 2,600, connection note 300, comment 1,250, InMail subject 200, InMail body 2,000, and direct message 8,000 characters. The feed also truncates posts at roughly 210 characters with a "see more" link, so your hook needs to land in the first line.
What is the LinkedIn headline character limit?
The LinkedIn headline limit is 220 characters. Use them: a keyword-rich headline that states who you help and how outperforms a bare job title, both for search inside LinkedIn and for the prospect deciding whether to accept your request.
What is the LinkedIn About section character limit?
The About (summary) section allows up to 2,600 characters. Only the first two or three lines show before a "see more" link on the profile, so lead with a strong hook and your core value, then expand. The counter above shows your live count against the 2,600 limit.
What is the LinkedIn InMail character limit?
InMail allows 200 characters for the subject line and 2,000 for the body. Shorter tends to perform better: a focused, relevant InMail under a few hundred characters usually beats a long pitch that fills the full 2,000.
