Facebook Feed caption character limit in 2026: 63,206 max. Truncation, optimal length, cross-platform strategy.
Facebook Feed caption character limit: 63,206 characters per post.
Facebook Feed's caption character limit in 2026 is 63,206 characters per post.
The optimal caption length for Facebook Feed engagement is well below the max. Captions that ride the ceiling are almost always padded — and Facebook Feed'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.
Facebook Feed doesn't surface a hashtag count limit, but tags still count against the 63,206-character total.
Truncation behavior: Facebook Feed 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 63,206 character pool.
Note: 240min cap is widely cited; SRT side-car upload supported.
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 63,206-character caption written for Facebook Feed 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 Facebook Feed.

63,206 characters per post.
Front-load the hook in the first 80-120 characters. Captions that ride the 63,206-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 63,206-character cap is the total including hashtags, @-mentions, and emoji. Plan accordingly.
Yes on most Facebook Feed surfaces. Edits don't reset the post's distribution and don't re-trigger notifications — safe to fix typos or update CTAs without penalty.
