How to use this calculator

  2. Read the character count at the top.
  3. See letters, digits, spaces and symbols.
  4. Check the limits for SMS, X, SEO titles and meta descriptions.

The formula

Characters are counted as Unicode characters. Characters without spaces remove all spaces, tabs and line breaks. Bytes use UTF-8 encoding. An SMS holds 160 characters, or 70 if the text has non-English characters.

Worked example

"Hello world! 123" has 16 characters, or 14 without spaces. It has 10 letters, 3 digits and 2 spaces, and takes 1 SMS and fits an X post with 264 characters left.

Understanding your result

Tamil and other non-English text takes 3 bytes per character and uses the shorter 70-character SMS limit. Search engines show roughly 60 characters of a title and 160 of a description.

When to use it

  • Fit a post, caption or SMS into a limit.
  • Write SEO titles and meta descriptions.
  • Check form fields with character limits.

Assumptions and limits

Platform limits change, so check the platform for the current limit. Your text is processed in your browser only and never added to the page address.
