LinkedIn post character counter
Posts allow 3,000 characters, with about 140 visible before “see more”. The expand click is itself an engagement signal, so the opening line does double duty.

The 140-character opening
LinkedIn collapses posts at roughly 140 characters on desktop and around 100 on mobile. Those first words decide whether anyone reads the rest.
Openings that work tend to state a specific claim, a number, or a genuine surprise. Openings that fail tend to begin with throat-clearing: “I've been thinking a lot lately about…”
