Moving content from X (Twitter) to Facebook is the opposite pressure from most cross-posting routes: instead of squeezing, you expand. X forces standard accounts to think in 280 characters — every word earns its place, hooks land in the opening clause, and threads carry anything that needs more room. Facebook’s feed accepts up to 63,206 characters and surfaces long-form posts to audiences who expect context, warmth, and a complete thought in a single post. A bare 280-character X post dropped into Facebook often reads as unfinished or oddly terse for the platform.
The other high-friction delta is audience culture. X readers tolerate clipped syntax, abbreviations, and naked links to t.co-shortened URLs. Facebook audiences tend to engage more with a narrative arc — a bit of setup, the core point, and a clear call to action — and they see the full expanded URL rather than a t.co shortlink. This guide maps what transfers cleanly, what needs rebuilding, and the exact steps to turn an X post or thread into a Facebook update that earns reach on its own terms.

Everything that changes between the two composers, side by side.
| Spec | X (Twitter) (from) | Facebook (to) |
|---|---|---|
| Primary canvas | 1600 × 900 px · 16:9 (post image) | 1080 × 1350 px · 4:5 (post) |
| Caption limit | 280 characters (X Premium subscribers can post up to 25,000) | 63,206 characters (feed truncates after a few lines with “See more”) |
| Video length | About 2 minutes 20 seconds for standard accounts; longer uploads are a Premium feature | Long feed uploads supported (hours); Facebook Reels are far shorter — check the composer for your account’s cap |
| Hashtags | Count toward the character limit; one or two is the platform norm | Supported but lightly used — one or two at most reads native on Facebook |
| Link presentation | Every URL is wrapped in a t.co redirect and counts toward the 280-character limit | Full destination URL generates a link-preview card; the URL does not count against the 63,206-character post limit |
| Content depth expected | Brevity is rewarded — 280 characters for standard accounts forces a single hook or idea | Feed truncates after a few lines with "See more" — posts with enough body to earn the expand tend to get more engagement |
| Thread / multi-part format | Threads let you chain unlimited connected tweets in a reply chain | No native thread format — multi-part content should be unified into one long post or a series of separate posts |

Tip 1
Use the thread as an outline, not a paste: if your original content lived in a thread, treat each tweet as a paragraph topic sentence and write a sentence or two of body under each — the result is a cohesive Facebook post rather than a bulleted thread dump.
Tip 2
Give the Facebook post a standalone CTA: X audiences often click through on pure curiosity; Facebook audiences are more likely to share or comment if the post tells them exactly what to do next — "read the full breakdown at [link]" outperforms "check this out".
Tip 3
Post the image even if it felt optional on X: Facebook’s algorithm has long favored posts with visual media over text-only posts, and an image that was decorative on X can be the engagement driver on Facebook.

You can, but a 280-character X post typically reads as a fragment on Facebook, where audiences expect more context. Pasting verbatim also preserves t.co links, platform-specific phrasing, and mentions that won’t resolve correctly on Facebook. A quick expansion — adding a sentence or two of background and swapping the links — produces a much better result for Facebook’s audience and its feed algorithm.
There is no native export for a thread as a single object. Copy each tweet in order and use them as paragraph starters: write one or two sentences of body under each tweet’s idea, then combine everything into a single Facebook post. The result reads as a self-contained long-form update rather than a list of raw tweets.
X automatically wraps every URL in a t.co redirect when the post is published. If you copy text from X, the visible URL may already be the destination but the underlying href is a t.co address. Facebook’s link-preview crawler follows the redirect and usually generates a card, but the display URL shown to readers is the t.co shortlink, which looks unpolished. Paste the full destination URL directly into the Facebook post body to ensure a clean preview.
The norms align — one or two focused tags is the convention on both platforms — but the rationale differs. On X, hashtags count against the 280-character limit for standard accounts, so each one has a real character cost. On Facebook, the character budget is 63,206 characters, so the limit isn’t a concern, but more than two tags still reads as spam. Carry over only the tags that describe the content in a way Facebook users would actually search; drop any X trending tags that have no equivalent community on Facebook.
Compose once, customize the caption per network, and let SocialKit publish to X (Twitter), Facebook, and 9 more platforms on schedule — no re-uploading, no copy-paste.
