LinkedIn ad character limits

LinkedIn gives you more headline room than any other platform — 70 characters — but truncates intro text early on desktop. Here's what shows before the fold.

LinkedIn Sponsored Content (single image, document, and carousel ads) shares a copy structure: intro text above the creative, then a headline below. Intro text allows up to 600 characters but truncates around 150 on desktop, so the hook has to land fast for a skimming professional audience.

Common Mistakes

  • Treating the 70-character headline like a 30-character one and wasting the room.
  • Writing 600 characters of intro text when only ~150 show before “see more.”
  • Forgetting the audience is B2B and skimming during work — bury the value and they scroll.
