Posts: 3,000 characters
LinkedIn says it plainly: a post can have up to 3,000 characters, and the same goes for posts in groups. That's roughly 400 to 600 words. Anything longer belongs in an article.
Bold or italic words don't change that. LinkedIn has no formatting in posts, so styled text is made of Unicode characters, each still one character. Our LinkedIn text formatter styles words that way and counts as you type.
Articles: 125,000 characters
Articles, LinkedIn's long-form format, are limited to 125,000 characters, about 40 times a post.
Comments: 1,250 characters
LinkedIn's help center lists 1,250 characters for comments in groups. Lempile's API applies the same cap to every comment and reply, and refuses a longer one before anything is sent.
Connection notes: 200 characters
A note on a connection request can be up to 200 characters. On a free account, LinkedIn lets you personalize up to three connection requests a month; Premium members can personalize all of theirs, though connection request limits still apply. More on those in LinkedIn connection and invitation limits.
InMail: 200 + 1,900 characters
An InMail needs a subject of up to 200 characters, and its body takes up to 1,900.
Headline and About
LinkedIn's help center doesn't state a limit for the profile headline. Guides widely report 220 characters, and the counter in LinkedIn's profile editor shows the real limit for your account; the counter above marks that number as reported. For the About section, LinkedIn's Talent Blog gives 2,600 characters. To write one, try the LinkedIn summary generator.
How characters are counted
Every character counts once: letters, spaces, line breaks and punctuation. The counter above counts the way Lempile's API does, one per Unicode code point. Some emoji are made of several code points (flags, skin tones, families) and count as several, so keep a small margin under each limit.
