Working with String Length Calculator

Check the length of a field value, label, or message before using it in an application. The workspace also shows words and other text statistics, making it useful when several limits apply. Pay attention to the distinction between visible characters and the units a particular system counts.

How to use String Length Calculator

  1. Paste or type the text you want to measure.
  2. Review character counts with and without spaces, plus the other available text statistics.
  3. Adjust the text and watch the counts update before copying it back to your application.

String Length Calculator example

Paste a product description and compare the count including spaces with the count excluding them. Test an emoji or accented character if your destination has a strict technical limit.

What to expect from the result

JavaScript string length and a platform's character or byte limit can differ, especially for emoji and combined Unicode characters. Confirm the destination's counting rules.
