This is the {{Str len}} meta-template.

It takes a string as parameter and returns its length (excluding those at the start and end).

Note: if you want to edit this template, first try your modifications on {{Str len/sandbox}}.You can then test your edits in {{Str len/testcases}}.
When the new version is ready, you can move it to the main template.

Examples

If the parameter is empty or undefined it is considered to be of zero length:

{{str len}} returns 0

{{str len|}} returns 0

{{str len| }} returns 0

It counts the length correctly, even if the string contains spaces, looks like a number, or contains special characters:

{{str len| ab cde }} returns 6

{{str len| 1234567 }} returns 7

{{str len| café åäö }} returns 8

It can measure strings over 500 in length:

{{str len| 499-characters... }} returns 499

{{str len| 1000-characters... }} returns 1000

{{Trunc}} – To trim down to a specified number of characters.
{{Trim}} — To trim any leading or trailing whitespace.
{{Str left}} – To trim down to a specified number of characters, or duplicate the string to a specified number.
{{Str right}}
{{Strip}} – To strip (remove) a given number of characters from the beginning/end of the string
