About this tool
Count characters, words, and check text length limits for Twitter, SMS, meta descriptions, and other platforms with character restrictions. This character counter provides real-time counting as you type, showing both total characters and remaining characters for your selected platform.
Different platforms have different character limits: Twitter posts allow 280 characters, SMS messages typically limit to 160 characters, and Google meta descriptions work best at 150-160 characters. This tool helps you stay within limits while crafting your messages.
Content creators, social media managers, copywriters, and SEO specialists use character counters daily to optimize content. Write the perfect tweet, craft compelling meta descriptions that won't get cut off, or ensure your SMS marketing messages fit within a single message unit.
The counter tracks multiple metrics simultaneously: total characters (with and without spaces), letters only (excluding punctuation and numbers), and remaining characters for your selected platform. Perfect for precise content creation where every character counts.
