To post on Threads from a desktop, open threads.com, sign in with your Instagram account, write up to 500 characters, add images or a video and click Post, or use the menu in the composer to schedule it. To plan Threads with your other channels, schedule it in SkedCast.
Key takeaways
- Threads's real caption limit is 500 characters.
- Threads’s publishing API has no scheduled-publish field, so SkedCast’s own engine holds the post and publishes it on time.
- The manual, native way to post is below, alongside exactly what SkedCast automates on top of it.
How to post on Threads from desktop, manually
The native, no-scheduler way to post on Threads, step by step:
- Open threads.com in a desktop browser and sign in with the Instagram account your Threads profile is tied to.
- Click the compose icon and write your post — Threads caps a single post at 500 characters, and only recognizes one hashtag per post (extras appear as plain text and still count against the limit).
- Attach up to 20 images or 1 video (not both in the same post).
- Click Post, or open the menu in the composer and choose Schedule to pick a date and time.
How to schedule it automatically with SkedCast
The Threads scheduler puts Threads on the same content calendar as your other channels, and bulk scheduling fills it from one spreadsheet. What SkedCast adds on top of the manual flow above:
- SkedCast connects through the same Instagram identity Threads itself uses, and schedules Threads alongside every other channel from one calendar.
- The composer enforces the real 500-character limit and single-hashtag behavior live, so a post can’t be scheduled that Threads would truncate or misrender.
- Compose once and publish to Threads alongside Instagram and every other platform you manage from the same post.
- A video posts alone — SkedCast blocks mixing a video into an image carousel before you can schedule it, matching Threads’ own rule.
FAQ
- Can I schedule a Threads post directly from the Threads website?
- Yes. Since January 2025 the Threads composer has a schedule option in its menu. Scheduled posts wait in your drafts until they publish. SkedCast adds a shared calendar with your other channels.
- Why does connecting Threads to SkedCast ask for my Instagram login?
- Threads doesn’t have a separate login of its own — it authenticates through your Instagram account, so signing in with Instagram is the correct, expected step.
- What is the character limit for a Threads post?
- 500 characters. SkedCast’s composer counts the way Threads does and warns before you schedule a post that is too long.
- Can you schedule Threads posts in advance with SkedCast?
- Yes. SkedCast holds the post and publishes it at the time you set, because Threads’s publishing API has no scheduled-publish field. You plan from one calendar with your other channels.
- Can you post to several Threads accounts at once?
- Yes. Write the post once in SkedCast, pick every Threads account it should go to, and SkedCast publishes to each, spacing the posts out per account so they do not all land in the same minute.
