What is a Character Counter?
A character counter is a free online tool that instantly counts the number of characters, letters, numbers, spaces, and special characters in any text you type or paste. Unlike word counters that focus on word count, character counters help you track the exact length of your text—essential for social media posts, SMS messages, meta descriptions, and any platform with character limits.
Character counting is critical in modern digital communication. Twitter limits tweets to 280 characters. Instagram bios max out at 150. Google displays roughly 160 characters of your meta description in search results. SMS messages split after 160 characters, potentially costing you extra. Our character counter tool helps you stay within these limits while crafting the perfect message.
Beyond simple counting, this tool provides detailed character analysis: total characters (with spaces), characters without spaces, letter-only count, number count, space count, and special character count. You'll also see real-time platform limit warnings with color-coded indicators—green when you're safe, yellow when approaching limits, and red when over.
