What is Caption Checker?

The Caption Checker validates your social media caption against the character limits of major platforms. Instagram allows 2,200 characters, Twitter allows 280, LinkedIn allows 3,000, TikTok allows 2,200, and Facebook allows 63,206. You enter your caption and the tool shows the count, remaining characters, and whether it fits each platform. All processing happens in the browser.

How does Caption Checker work?

This tool counts the characters in your caption text and compares against known limits for five platforms. It shows a status indicator per platform with the exact character count and remaining allowance.
