Social Media Post Preview - See Where 'More' Cuts Your Caption
See where each platform cuts your caption with 'more'.
Updated October 2026
Your caption appears here
The hook has to land inside the visible part. Put the main idea in the first sentence, then the blank line, then the rest.
Private by design: your files are processed on your own device and never uploaded.
How to use
- 1 Paste your caption or post.
- 2 Tap a platform. ✓ means the whole text is visible, ✂ means it is cut with a 'more' link.
- 3 Read the phone mock-up: the grey part is hidden until someone taps 'more'.
- 4 Move your hook into the visible part, then copy the final text.
Why the first line decides everything
Every platform truncates long posts in the feed. Instagram shows about 125 characters, LinkedIn 210, Facebook 477, TikTok 100 and YouTube descriptions 150 before a 'more' link. Instagram and LinkedIn also cut at the first blank line if it comes earlier. Most people never tap 'more', so the visible part has to carry the hook, the promise and ideally the call to action.
How to write for the cut
Put the strongest sentence first and keep it under the platform's visible limit. Avoid a blank line right after the first sentence on Instagram and LinkedIn, because the cut happens there. Use the hidden part for detail, links and hashtags. This preview updates live so you can see the effect of every edit.

Guides that use this tool
Questions
Is the preview pixel-exact?
It uses each platform's published character cut-offs. Exact wrapping depends on the phone, but the cut point is the same.
Does the preview post anything?
No. It only renders your text locally.
Why does Instagram cut earlier than 125 characters?
Because you have a blank line before that point. Instagram truncates at the first blank line.
Can I preview with an image?
A placeholder image is shown to match the feed layout. Your own image is not needed for the text cut-off.
Does it work for comments?
Comments use similar limits but are not truncated the same way; use the Character Counter for comments.
