Caption Length Checker

Summary

Type or paste your caption and instantly see how many characters remain for each major social platform.

How it works

1. Type or paste your caption text into the input area.
2. The tool counts characters instantly as you type.
3. Each platform card shows characters used, characters remaining, and a progress bar.
4. The bar turns yellow when you reach 80% of the limit and red when you exceed it.
5. Edit your caption until all the platforms you care about are in the green.

Use cases

• Check whether a draft Instagram caption fits within 2,200 characters.
• Trim a thread post to stay under Twitter/X's 280-character limit.
• Verify a LinkedIn article update fits the 3,000-character window.
• Batch-check captions before scheduling posts across multiple networks.
• Catch accidental over-length captions before they get cut off mid-sentence.
• Compare how the same caption fits across different platforms at a glance.
