ConverterCharacter Counter
Measure the length of a single-line text value, with totals for JavaScript string units, non-whitespace units, and words. Use the result to check a field limit, then compare it with the counting rules of the destination platform.
What The Totals Mean
The total uses JavaScript string length. Letters, digits, punctuation, and spaces contribute to the count; the no-spaces value removes whitespace before counting.
Some emoji and supplementary Unicode characters occupy two UTF-16 code units, so this total may differ from a platform that counts user-perceived characters or Unicode code points. The input is a single-line field, not a multi-line editor.
Useful Checks
| Input | What to verify |
|---|---|
| Hello world | 11 units including the space; 10 without whitespace |
| product-42 | Letters, punctuation, and digits all contribute |
| Emoji or combined characters | Compare with the destination platform before enforcing a strict limit |
When A Platform Limit Matters
- Check whether spaces, line breaks, URLs, or emoji use special counting rules on the destination platform.
- Paste the final text rather than an earlier draft because every edit can change the total.
- Do not describe this integer count as a rounded or approximate conversion result.

Frequently Asked Questions
Yes. The main total includes spaces, while the separate no-spaces value removes whitespace before counting.
This tool uses JavaScript UTF-16 string length. Another platform may count Unicode code points or user-perceived characters instead.
This route uses a single-line input. Use Word Counter when you need a multi-line draft editor with broader text indicators.
