What is a character counter?
A character counter is a text-analysis tool that tallies every character in a piece of writing — letters, numbers, spaces, punctuation marks and symbols. This one runs entirely as JavaScript inside your browser, so there's no upload and no server round-trip: your text never leaves your device. Every count updates live as you type or paste, and resets the moment you clear the box.
With spaces vs. without spaces
Most platforms with a hard limit — X/Twitter, SMS, meta descriptions, ad headlines — count spaces toward the total. Some contexts, like translation or transcription pricing, quote by characters excluding spaces instead. Use the toggle above to switch between the two, and check whichever figure applies to your use case.
How characters are counted
The tool counts Unicode code points, the same convention modern browsers and programming languages use. Letters, digits and punctuation each count as one character. Accented letters like é or ñ count as one; a visible emoji generally counts as one glyph, though some platforms internally count certain emoji as two to four characters.
Why character count matters
- Social media — X/Twitter, SMS and other platforms cut off or reject text past a hard character limit.
- SEO — title tags and meta descriptions are truncated in search results past a set character length.
- Forms and databases — usernames, product codes and database fields often enforce a maximum character length.
- Translation & transcription — many services price work per 1,000 characters, usually excluding spaces.
- Typesetting — designers use character counts to estimate how much space a block of copy will take up.
