How to schedule Threads image carousels

To schedule a Threads carousel, upload the images in the order you want them to appear to a third-party scheduler connected via the Threads API, write the shared caption, and set the publish time — Threads does not have native third-party-facing scheduling built into the app itself, so this always goes through a connected tool.

To schedule a Threads carousel, add up to 20 images in the order they should appear, write the post text and pick a publish time. SkedCast publishes Threads carousels through the Threads API, alongside Threads text posts, threads and video, on one calendar with your other networks.

Key takeaways

  • Threads carousels are multiple images published as one swipeable post, similar to an Instagram carousel.
  • Scheduling a Threads carousel requires a third-party tool connected via the Threads API — check that your specific tool supports carousels, not only single-image posts.
  • Slide order is set by the upload order in the composer and generally cannot be changed once the post is live.
  • Threads carousel support is newer than Instagram’s, so confirm current support in your tool rather than assuming feature parity with Instagram.

A Threads carousel is several images published together as one post that a viewer swipes through, the same underlying idea as an Instagram carousel. Not every scheduler that supports Threads supports carousels specifically — some handle only single-image or text posts.

Scheduling one

Upload the images to a connected scheduler’s composer in the order you want them to appear, write the caption that will show under the whole carousel, and set the publish time. The tool publishes it through the Threads API at that time as a single multi-image post.

Check current support before relying on it

Carousel support on Threads, both on the platform and in third-party tools, is newer than the equivalent feature on Instagram. If carousels are a regular part of your Threads content, confirm your specific tool’s current support rather than assuming it matches what the same tool offers for Instagram.

FAQ

Can I reorder Threads carousel slides after scheduling?
You can typically edit the order any time before the scheduled post publishes, but not after it goes live — this matches how carousel reordering works on Instagram.
Does every Threads-supporting scheduler also support carousels?
No, carousel support is not guaranteed just because a tool schedules Threads posts generally — check your specific tool for explicit carousel support before relying on it.
Can I schedule Threads posts in bulk?
Yes. SkedCast's bulk import schedules a whole batch from a CSV, Excel file or Google Sheet in one upload.
Can I schedule Threads posts for free?
Yes. SkedCast's permanent free plan schedules posts with no card and no time limit.
What happens if a scheduled Threads post fails?
SkedCast shows the exact reason on the post, such as an expired connection or a rejected file, so you can fix it and retry.
