Character Count Calculator
Every major social media platform imposes character limits on posts, and knowing exactly where you stand prevents truncated captions, rejected copy, and embarrassing cut-off sentences. This character count calculator displays real-time character totals and shows characters remaining for four major platforms: Twitter (X) at 280 characters, LinkedIn posts at 3,000 characters, Instagram captions at 2,200 characters, and Facebook (Meta) posts at 63,206 characters. The remaining count turns red when you exceed the platform limit, giving you instant visual feedback. The tool also shows total characters with spaces and without spaces, and total word count. All counting happens in your browser instantly as you type. Paste your draft social media post into the text area below and check all four limits simultaneously before publishing.
