A 400-character caption on LinkedIn
LinkedIn shows about the first 210 characters before "…more", so 190 of the 400 are hidden until someone taps. Put the hook in those first 210.
LinkedIn caption generator
To write a LinkedIn caption, type what the post is about and this generator gives several caption starters, each built as a professional hook, a value statement and a question 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. LinkedIn posts take up to 3,000 characters, shows about 210 before "…more".

How long can a LinkedIn post be?
3,000 characters, the limit in LinkedIn’s Help Center and the one SkedCast checks as you type. Most readers decide from the first two or three lines, because LinkedIn folds the rest behind “see more”:
| Part | Limit | Notes |
|---|---|---|
| Post text | 3,000 characters | Spaces, links, hashtags and mentions included |
| Shown before “see more” | About the first 210 characters | The opening two or three lines decide the click |
| Images per post | Up to 20 | Or one video or one document |

How do you write a good LinkedIn post?
Lead with the reason to click “see more”, then keep the rest easy to scan. A post that works usually has:
- An opening line that states the point, a result or a question, not a preamble.
- Short paragraphs with white space, so the post reads on a phone.
- One idea, backed by a specific example, number or lesson.
- One clear ask: a question for the comments, a link, or a follow.
- A few relevant hashtags at the end, if any.
Can AI write LinkedIn posts?
Yes. This free generator uses caption templates, so its suggestions are a starting point you edit. Inside SkedCast’s composer, AI drafts a post from your idea and rewrites one you have written, and you can keep a separate version for each network, with 25 AI credits a month on the free plan. Read every AI draft before it goes out: your experience is what makes a LinkedIn post worth reading.
How do you use the LinkedIn caption generator?
- Describe what you’re posting about. Type a short topic or product description related to your LinkedIn post — a few words is enough.
- Read the LinkedIn captions. Each result fills your topic into a different caption formula built for LinkedIn’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 LinkedIn.
- 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 LinkedIn post.
What are the LinkedIn rules to know?
The limits SkedCast’s composer checks for LinkedIn before a post goes out, read from the same rules table the composer uses.
| Text limit | 3,000 characters |
|---|---|
| How length is counted | As you see it: one emoji or accented letter counts as one character |
| Hashtags | No hashtag cap enforced |
| Where the caption is cut off in the feed | About 210 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 | 1:1 in the feed preview |
| Images | up to 20 per post · JPEG, PNG, GIF · max 5 MB each · aspect ratio 4:5 to 1.91:1 |
Good to know
- LinkedIn has no native scheduling — SkedCast schedules and publishes these posts.
- A poll cannot be combined with media — a LinkedIn post carries a poll OR images/video.
- LinkedIn has no Stories, Reels, or threaded posts.
- LinkedIn does not auto-shorten links — a URL counts toward the 3,000-character limit at full length.
- Standard feed posts have no separate title field (only Articles, which are not offered here).
What does it look like in practice?
Filling in one topic several ways
Type a topic like "spring collection launch" once and get 6 to 8 different LinkedIn caption starters built from that same topic — a question hook, a bold claim and more.
How do you schedule LinkedIn posts?
In SkedCast, write the post for your profile or a Company Page, add up to 20 images, a video or a document, and pick a time. SkedCast checks the text against LinkedIn’s 3,000-character limit and shows a preview with the “see more” fold, and can add a first comment. See the LinkedIn scheduler for every option.
LinkedIn caption generator FAQ
- Which caption formulas does the LinkedIn generator use?
- A mix of hooks, statements and calls-to-action shaped for LinkedIn — a professional hook, a value statement and a question call-to-action — pulled from common caption patterns rather than written fresh by a language model.
- Can I post text only on LinkedIn?
- Yes. LinkedIn accepts a text-only post, up to 3,000 characters.
- Will LinkedIn cut off a long caption?
- In the feed, yes: LinkedIn shows roughly the first 210 characters and hides the rest behind "…more", so put the hook and any call to action first.
- How many hashtags can a LinkedIn post have?
- SkedCast enforces no hashtag cap for LinkedIn; the practical limit is the 3,000-character text limit and what reads well.
- What happens to a link in a LinkedIn post?
- The link counts at its real length, and LinkedIn shows a link-preview card for it.
- Does this LinkedIn caption generator use AI?
- No. It fills your topic into a set of proven LinkedIn caption templates entirely in your browser — no language model writes or personalizes the text, so treat every result as a starting point to edit.
- How long can a LinkedIn post be?
- Up to 3,000 characters, per LinkedIn’s Help Center. Only about the first 210 show before “see more”.

- This free tool uses templates. In SkedCast’s composer, AI drafts and rewrites posts, with 25 AI credits a month on the free plan.
