LinkedIn Character Limit: Every Field
The current limits, where your text actually gets cut off, and a free tool to check your draft.
The short answer
A LinkedIn post can be up to 3,000 characters. Your profile headline is capped at 220 characters, the About section at 2,600, and if you need genuine long-form, LinkedIn articles allow a huge 110,000 characters.
Like Instagram, LinkedIn folds posts in the feed: only about the first 200–210 characters show before the 'see more' link. The fold is where posts live or die — LinkedIn's algorithm heavily weights whether readers click 'see more', so the opening two lines function as your headline, hook, and ad all at once.

Writing effectively within the limit
The 3,000-character cap is generous, but reach on LinkedIn is won in the first 210. Draft the post, then rewrite the first two lines five times. A reliable pattern: a one-line claim that creates tension, a one-line stake ('here's why it matters'), then the 'see more' fold, then the substance in short 1-2 sentence paragraphs with white space.
