LinkedIn Single Image Ad Character Limits (2026)
LinkedIn Sponsored Content single-image ads cap intro text at 600 chars but show ~150 before the see-more clamp. Headline visible at 40, description often hidden.
LinkedIn Sponsored Content single-image ads run inside the same vertical feed as organic posts, which means they compete with thought-leadership posts, job updates, and industry news for attention from a B2B audience that scrolls fast but reads more deeply than on consumer platforms. The platform allows up to 600 characters of introductory text, but only the first 150 characters render before the "see more" clamp on mobile (about 210 on desktop). Headlines max out at 70 characters, but the visible window on the bottom card is closer to 40 on most modern phones. Description text is technically allowed up to 100 characters but is hidden entirely on most mobile placements, so treat it as a desktop-only flourish.
The strategic implication is straightforward: lead with the metric, the case study result, or the named-brand authority signal in the first sentence. LinkedIn audiences will read through "see more" at higher rates than Meta audiences when the first 150 characters earn the click — but only when those first 150 characters do real work. Generic openers like "Are you a marketer who…" cost you the entire intro budget.

What changed in 2026
LinkedIn extended the description-line allowance from 70 to 100 characters in early 2026 but kept the mobile-feed clamp unchanged — meaning description text now renders even less reliably than before. The platform also tightened the "see more" mobile clamp from ~210 characters down to ~150 on iPhone 14-class devices.
FAQ
- How many characters of intro text show before See more on LinkedIn?
- Approximately 150 characters on mobile and 210 on desktop. Plan for 140 as a safe budget if you must hit the visible window on every device.
- Does the description field appear on mobile?
- Rarely. On most mobile placements the description is hidden entirely. Use it for desktop reinforcement only — never rely on it.
- What is the optimal headline length for LinkedIn Sponsored Content?
- 27–40 characters. Headlines past 40 risk clipping by the CTA strip on smaller phones.
- Are emoji safe in LinkedIn intro text?
- Yes, but each emoji counts as one or more characters depending on grapheme cluster. Compound emoji (skin-tone modifiers, family glyphs) can eat 4–7 characters.
