Count characters instantly and check your text against popular platform limits like Twitter, SMS, and meta descriptions.
The JustTheTool Character Counter helps you stay within character limits for social media platforms, SMS messages, email subject lines, meta descriptions, and more. It updates in real time as you type.
Twitter / X: 280 characters per tweet. SMS: 160 characters per standard SMS message (longer messages are split into multiple SMS). Instagram caption: 2,200 characters. Meta description (SEO): 155–160 characters recommended. Google Ad headline: 30 characters. YouTube title: 100 characters. Email subject line: 60 characters recommended for full display.
Most English characters use 1 byte each. However, emoji and special Unicode characters can use 2–4 bytes. The byte count shown helps when working with databases or APIs that have byte-based limits.
