LinkedIn hides everything after about 210 characters

Paste a post above and the counter measures it against LinkedIn's 3,000-character limit while marking the fold, which on LinkedIn arrives after roughly three short lines.

The count runs locally as you type, so an unpublished post about your own company never leaves the browser.

LinkedIn posts cap at 3,000 characters, but the feed shows only about 210 before the See more link. That is roughly three short lines. Everything you want a scrolling reader to see has to fit above that fold, and the counter marks where it falls so you are not guessing.

The practical shape that follows is a one-line hook, a deliberate line break, then the body. Line breaks survive truncation and give the opening room to breathe, which matters more on LinkedIn than on any other feed because the default post renders as a dense grey block that the eye slides straight past.

External links are the other LinkedIn-specific decision. A link in the post body counts its full character length here, unlike on X where every URL costs a flat 23, so a long tracking URL genuinely eats into your 3,000. Plenty of accounts move the link to the first comment to keep the post text clean. Either approach works as long as you are consistent enough that your audience knows where to look.

Your headline is a separate 220-character field and it is searchable, so front-load the role and the outcome you deliver rather than adjectives about how passionate you are. Three to five hashtags is the usual ceiling. LinkedIn does not enforce a cap, but tags render inline with the post text, so a long run of them pushes your actual words below the fold.
