Free Social Media Character Counter for All Platforms
The FlowShorts Social Media Character Counter is a free tool that counts characters, words, sentences, hashtags, and emojis in real time. It shows platform-specific character limits with visual progress bars for TikTok (2,200), Instagram (2,200), YouTube titles (100), YouTube descriptions (5,000), X/Twitter (280), LinkedIn (3,000), and Facebook (63,206). No signup required.
How It Works
Type or paste your text into the editor. The tool instantly counts characters, words, sentences, hashtags, and emojis. Platform-specific progress bars show how much of each limit you have used, turning yellow at 80% and red when you exceed the limit. Use this to craft perfectly-sized posts for every platform.

TikTok captions between 50-150 characters drive the most engagement. X/Twitter sweet spot is 71-100 characters. LinkedIn posts perform best between 1,200-1,600 characters. Use this tool to hit the optimal length for each platform.
