This is the {{tl|str len}} meta-template.

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

~~'''{{Note:}}''' For most usage cases it is much easier and costs much less server resources to use {{tl|str ≥ len}} or one of its sister templates. See the [[#See also|see also]] section below~~.

~~=== Technical details ===~~

MediaWiki has no parser function or magic word to measure string lengths. And measuring string length using template code is very heavy on the servers. Thus this template is as optimised as possible. But you should consider using {{tl|str ≥ len}} instead, since for most usage cases it is much easier to use and it costs much less server resources.

This template calls {{tl|str len/core}} which does most of the work. For documentation on the internal workings of these two templates see /core. The [[Template talk:Str len|talk page]] might also have more details.
