How to use the Social Media Character Counter
- 1
Write or paste your post.
- 2
Check each platform's limit and its preview cut-off.
- 3
Move your hook into the visible part, then copy the post.
Limits vs. what people see
The limit is how much you can post. The preview is how much people see before tapping "See more", and that's where the hook has to land. On LinkedIn it's roughly the first 210 characters; on Instagram captions, about 125.
Write for the cut-off
A structure that works across platforms:
- First line: the hook or the result
- Second line: why it matters to the reader
- Then the detail, steps or story
- End with one clear call to action
