To post on X from a computer, open x.com, click Post, write up to 280 characters, add up to four images, a GIF, a video or a poll, and click Post. Many accounts also see a schedule icon in the web composer. SkedCast schedules X posts from one calendar with your other channels.
Key takeaways
- X (Twitter)'s real caption limit is 280 characters.
- X (Twitter)’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 X from a computer, manually
The native, no-scheduler way to post on X (Twitter), step by step:
- Open x.com or the X app and sign in.
- Click the compose button and write your post — X caps a post at 280 characters, counted with weighted rules (most emoji count as 2 characters, and any URL always counts as 23 characters via X’s own t.co link wrapping, regardless of the URL’s real length).
- Attach up to 4 images, 1 GIF, or 1 video (never a mix), or add a poll instead (a poll can’t be combined with media).
- Click Post, or, if your account shows the schedule icon under the compose box, pick a date and time.
How to schedule it automatically with SkedCast
The X (Twitter) scheduler puts X (Twitter) 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 X’s official OAuth 2.0 sign-in and holds each post in its own queue, publishing it at the time you set.
- The composer counts characters the same weighted way X does — emoji and links included — so you see the real remaining count before you schedule, not an approximation.
- Compose once and fan the same post out to X alongside every other platform you manage.
- Bulk-import a batch of posts from a spreadsheet and let SkedCast auto-distribute them across a schedule, instead of posting one at a time.

FAQ
- Can I schedule a post on X without a third-party tool?
- Sometimes. Many accounts see a schedule icon under the compose box on x.com, and X’s Ads composer schedules posts; the mobile app cannot. A scheduler such as SkedCast schedules any account, from one calendar with your other channels.
- Why does a short link still use up so many characters on X?
- X always counts any URL as exactly 23 characters through its own t.co wrapping, no matter how long or short the real link is — so a link always costs the same 23 characters against your 280-character limit.
- What is the character limit for a X (Twitter) post?
- 280 characters. SkedCast’s composer counts the way X (Twitter) does and warns before you schedule a post that is too long.
- Can you schedule X (Twitter) posts in advance with SkedCast?
- Yes. SkedCast holds the post and publishes it at the time you set, because X (Twitter)’s publishing API has no scheduled-publish field. You plan from one calendar with your other channels.
- Can you post to several X (Twitter) accounts at once?
- Yes. Write the post once in SkedCast, pick every X (Twitter) 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.
