A 400-character caption on Instagram
Instagram shows about the first 125 characters before "…more", so 275 of the 400 are hidden until someone taps. Put the hook in those first 125.
Instagram caption generator
To write a Instagram caption, type what the post is about and this generator gives several caption starters, each built as a casual hook, a short body and a soft call-to-action. 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. Instagram posts take up to 2,200 characters, shows about 125 before "…more", and allows up to 30 hashtags.

How do you use the Instagram caption generator?
- Describe what you’re posting about. Type a short topic or product description related to your Instagram post — a few words is enough.
- Read the Instagram captions. Each result fills your topic into a different caption formula built for Instagram’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 Instagram.
- 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 Instagram post.
What are the Instagram rules to know?
The limits SkedCast’s composer checks for Instagram before a post goes out, read from the same rules table the composer uses.
| Text limit | 2,200 characters |
|---|---|
| How length is counted | As you see it: one emoji or accented letter counts as one character |
| Hashtags | Up to 30 per post; extras are flagged before publishing |
| @-mentions | Up to 20 per caption; extras are dropped |
| Where the caption is cut off in the feed | About 125 characters before "…more", so lead with the point |
| Text-only posts | Not allowed: every post needs an image or video |
| Links in the text | No link-preview card |
| First comment | Supported: SkedCast can post a first comment right after publishing |
| Feed crop | 4:5 in the feed preview |

Good to know
- Instagram cannot post text without media — every post needs at least one image or video.
- Instagram Reels processing is asynchronous — a Reel may take a moment to finish encoding before it appears.
- Instagram does not support animated GIF posts via the publishing API.
- Instagram does not support clickable links in captions — a pasted URL is inert plain text.
- Instagram does not support link-preview cards, polls, or a separate title field.
What does it look like in practice?
35 hashtags on Instagram
That is 5 over the 30 SkedCast allows for Instagram, so the post is flagged before it publishes rather than going out with tags dropped.
Instagram caption generator FAQ
- Which caption formulas does the Instagram generator use?
- A mix of hooks, statements and calls-to-action shaped for Instagram — a casual hook, a short body and a soft call-to-action — pulled from common caption patterns rather than written fresh by a language model.
- Can I post text only on Instagram?
- No. Every Instagram post needs at least one image or video; the caption rides along with the media.
- Will Instagram cut off a long caption?
- In the feed, yes: Instagram shows roughly the first 125 characters and hides the rest behind "…more", so put the hook and any call to action first.
- How many hashtags can an Instagram post have?
- SkedCast flags anything over 30 hashtags on an Instagram post before it publishes, so a post never goes out with tags Instagram would drop.
- What happens to a link in an Instagram post?
- The link counts at its real length, and Instagram shows no link-preview card for it.
- Does this Instagram caption generator use AI?
- No. It fills your topic into a set of proven Instagram caption templates entirely in your browser — no language model writes or personalizes the text, so treat every result as a starting point to edit.
