Fit the limit exactly
Plenty of fields have a hard character cap — a text message, a tweet, an SEO title, a bio, a form input. This counter shows your total with and without spaces and tracks it against the common limits, colouring the bar red the moment you go over, so you can tighten the wording until it fits.
Counted the way software counts
Characters are tallied by Unicode code point, which matches how most systems measure length. It all happens in your browser as you type — nothing is uploaded — so counting a private message or an unpublished headline is completely safe.
