Character limits are everywhere — tweet length, SMS segments, meta descriptions, title tags — and a plain .length check in JavaScript doesn’t always tell you the whole story once emoji or multi-byte characters get involved. This tool counts accurately and shows you exactly where you stand against common platform limits.
What Is the Character Counter?
Type or paste text and instantly see its character count (by Unicode code point, not raw UTF-16 units), character count without spaces, UTF-8 byte size, and line count — plus live progress bars comparing your text length against six common platform limits like Twitter/X, SMS, and meta description length.
How to Use It
- Open the tool at /tools/character-counter.
- Type or paste your text into the box.
- Read the character/byte/line stats update live.
- Check the platform-limit progress bars to see how much room you have left.
Key Features
- Accurate Unicode-aware counting, so emoji and other non-BMP characters count as one character each, not two.
- UTF-8 byte size, useful for APIs, databases, and SMS gateways that bill or limit by byte count rather than character count.
- Six built-in platform limits, including Twitter/X, SMS, meta description, title tag, Instagram, and LinkedIn.
- 100% client-side — nothing you type is ever sent anywhere.
When to Use This Tool
- Writing SEO meta descriptions or title tags and need to stay under the recommended length.
- Drafting social media posts and want to confirm you’re within a platform’s character limit.
- Estimating SMS segment costs, since going over 160 characters typically splits a message into multiple segments.
