OpusDesk Hub What this tool does
Use this character counter online to count characters with spaces, characters without whitespace, and words in real time. It is built for social posts, SMS copy, meta descriptions, titles, and any writing task with a strict length limit.
How to use Character Counter
- Paste or Type Your Text. Paste any text into the character counter online and the totals update instantly. The tool counts characters with spaces, characters without whitespace, and words.
- Check Platform Limits. Use the character counter online to compare your text against Twitter/X posts, SMS messages, titles, and meta descriptions. This helps you trim copy before publishing.
- Edit Until It Fits. Adjust your text and watch the counts change in real time. Because the character counter online runs locally, drafts and private copy stay in your browser.
How this tool works
The component recalculates string length and derived counts as the editor changes, with no network request for the text.
- Engine: JavaScript string and whitespace analysis
- Supported input: plain Unicode text
- Output: characters with/without spaces, words and line counts
Worked example
Input: Hello world
Output: 11 characters including the space, 10 excluding spaces
Limits, edge cases, and troubleshooting
Use it for metadata, messages, bios, and form limits. Verify emoji-heavy text in the destination platform because grapheme rules differ.
- The entered text must fit in browser memory.
- Emoji and combined Unicode symbols may be counted differently from platform-specific limits.
When to use another workflow
Use the target platform's own counter when its limit is based on bytes, weighted characters, or proprietary parsing.

Frequently asked questions
What does this character counter online measure?
The character counter online measures JavaScript UTF-16 code units with and without whitespace, and whitespace-separated words. It is useful for social posts, SEO snippets, and writing limits.
Can I use this as a Twitter character counter?
Use it only as an approximate editing aid. Emoji, combined characters, links, platform rules and SMS encoding can use different counting methods. The platform composer is authoritative.
