LinkedIn caption character limit in 2026: 3,000 max. 5 hashtags max. Truncation, optimal length, cross-platform strategy.
LinkedIn caption character limit: 3,000 characters per post.
LinkedIn's caption character limit in 2026 is 3,000 characters per post.
The optimal caption length for LinkedIn engagement is well below the max. Captions that ride the ceiling are almost always padded — and LinkedIn's feed truncates long captions with a "...more" toggle that most viewers never tap. Aim for the first 80-120 characters to carry the hook so the visible-without-tap portion does the work; anything below the fold is for SEO and the small fraction of readers who expand.
Hashtags on LinkedIn: limit is 5 per post. Tight cap. Use the slots for niche keywords rather than generic high-volume tags. Hashtags count against the 3,000-character total.
Truncation behavior: LinkedIn cuts visible caption text at roughly 125-140 characters in feed view, then shows "...more" to expand. Mobile and desktop truncate at different points — design for the shorter mobile cut. Stories, swipe-up CTAs, and the link-in-bio reference all count against the same 3,000 character pool.
Note: 10min/5GB native upload widely cited.
Cross-platform caption strategy: write the long-form caption for the platform with the most generous limit (typically Facebook or YouTube description), then trim per-platform. A single 3,000-character caption written for LinkedIn won't survive a port to Twitter (280 chars) or Bluesky (300 chars) — plan the truncation chain. The comparison table below shows caption limits across the platforms most creators cross-post to alongside LinkedIn.

3,000 characters per post. Hashtags count against this total, max 5 per post.
Front-load the hook in the first 80-120 characters. Captions that ride the 3,000-character max almost always under-perform tight, hook-first captions of 150-300 characters.
Around 125-140 visible characters before showing "...more". Design the first sentence to stand alone — most viewers never tap to expand.
Yes. The 3,000-character cap is the total including hashtags, @-mentions, and emoji. Plan accordingly.
Yes on most LinkedIn surfaces. Edits don't reset the post's distribution and don't re-trigger notifications — safe to fix typos or update CTAs without penalty.
