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…”

Other LinkedIn limits worth knowing

The 3,000-character post limit is the one people hit, but the platform caps several other fields.

Limits for every other platform are collected under social media character counters.

Emoji generally cost two characters here. LinkedIn also counts the line breaks people use to space out posts, and a post formatted with a break between every sentence can lose several hundred characters to whitespace alone.
