A 400-character caption on Threads
Threads shows about the first 200 characters before "…more", so 200 of the 400 are hidden until someone taps. Put the hook in those first 200.
Threads caption generator
To write a Threads caption, type what the post is about and this generator gives several caption starters, each built as a short, punchy, hook-first line built for a casual, conversational feed. They come from templates, not AI, so pick the one closest to your voice, add your own details and links, then post or schedule it. Threads posts take up to 500 characters, shows about 200 before "…more", and allows up to 1 hashtags.

How do you use the Threads caption generator?
- Describe what you’re posting about. Type a short topic or product description related to your Threads post — a few words is enough.
- Read the Threads captions. Each result fills your topic into a different caption formula built for Threads’s tone and typical caption length.
- Pick the closest match. Scan the list for the hook and structure closest to what you actually want to say on Threads.
- Edit before you post. These are starting points, not finished captions — add your own specifics, links and voice before publishing.
- Copy and schedule. Copy the caption in one click, then paste it into SkedCast’s composer and schedule your Threads post.
What are the Threads rules to know?
The limits SkedCast’s composer checks for Threads before a post goes out, read from the same rules table the composer uses.
| Text limit | 500 characters |
|---|---|
| How length is counted | As you see it: one emoji or accented letter counts as one character |
| Hashtags | Up to 1 per post; extras are flagged before publishing |
| Where the caption is cut off in the feed | About 200 characters before "…more", so lead with the point |
| Text-only posts | Allowed |
| Links in the text | A pasted URL shows a link-preview card |
| First comment | Supported: SkedCast can post a first comment right after publishing |
| Feed crop | 4:5 in the feed preview |
| Images | up to 20 per post · JPEG, PNG · max 8 MB each · aspect ratio 1:10 to 10:1 |
Good to know
- Threads carousels are images-only — a video posts alone, never inside a carousel.
- Threads has no native scheduling — SkedCast controls the publish time.
- Threads links only one hashtag per post; extra hashtags appear as plain text and still eat into your 500 characters.
- Threads has no Stories, no documents/PDF posts, and no separate title field.
- Polls and reply-threads cannot be composed through SkedCast.
What does it look like in practice?
6 hashtags on Threads
That is 5 over the 1 SkedCast allows for Threads, so the post is flagged before it publishes rather than going out with tags dropped.
Threads caption generator FAQ
- Which caption formulas does the Threads generator use?
- A mix of hooks, statements and calls-to-action shaped for Threads — a short, punchy, hook-first line built for a casual, conversational feed — pulled from common caption patterns rather than written fresh by a language model.
- Can I post text only on Threads?
- Yes. Threads accepts a text-only post, up to 500 characters.
- Will Threads cut off a long caption?
- In the feed, yes: Threads shows roughly the first 200 characters and hides the rest behind "…more", so put the hook and any call to action first.
- How many hashtags can a Threads post have?
- SkedCast flags anything over 1 hashtags on a Threads post before it publishes, so a post never goes out with tags Threads would drop.
- What happens to a link in a Threads post?
- The link counts at its real length, and Threads shows a link-preview card for it.
- Does this Threads caption generator use AI?
- No. It fills your topic into a set of proven Threads caption templates entirely in your browser — no language model writes or personalizes the text, so treat every result as a starting point to edit.
