Easy to use and efficient string length comparison templates:
{{Navbox with collapsible groups
| name = String-handling templates
| state = {{{state|expanded}}}
| bodyclass = plainlist
| title = String-handling templates
| selected = {{{selected|{{{expanded|{{{1|}}}}}}}}}


* {{tl|str ≥ len}} – To check if a string is "longer or equally long" vs. "shorter" than a given length.
<!---------------------- Trimming ------------------------->
* {{tl|str ≤ len}} – To check if a string is "shorter or equally long" vs. "longer" than a given length.
| abbr1 = trim
* {{tl|str ≠ len}} – To check if a string is "not equal" vs. "equal" to a given length.
| sect1 = [[Trimming (computer programming)|Trimming]]
* {{tl|str ≤ ≥ len}} – To check all three of "shorter", "equal" and "longer" at the same time.

Much less efficient string length template:
  | group1 = By counting
  | list1 =
  {{Aligned table |fullwidth=on |style=text-align:left; |col1width=50%;
    | {{Aligned table |style=padding-right:2.5em;
      |col1style=width:12.5em;text-align:right;white-space:nowrap;padding-right:0.75em;
      | {{tl|str mid}}      | To return a substring specified by position and length.
      | {{tl|trunc}}        | To trim down to a specified number of characters.
      | {{tl|str left}}      | To trim down to a specified number of characters or duplicate the string to a specified number.
      | {{tl|str crop}}      | To crop a specified number of characters off the end.
      | {{tl|chop head and tail}} | To crop a specified number of characters off the beginning and end.
      }}
    | {{Aligned table
      |col1style=width:12.5em;text-align:right;white-space:nowrap;padding-right:0.75em;
      | {{tl|str right}}    | To trim the first specified number of characters.
      | {{tl|str rightc}}    | To return a number of characters from the end, returns a parameter if the string is empty.
      | {{tl|str rightmost}} | To trim down to the last specified number of characters.
      | {{tl|str sub old}}  | To trim down to a specified number, starting at a given number from the left.
      | {{tl|str sub new}}  | Select a substr based on starting and ending index.
      | {{tl|str index}}    | Returns a given character from a string, but not accented letters.
      | {{tl|Plain text}}, {{tl|Nowiki}}    | Strips wikicode from a string.
  }} }}


* {{tl|str len}} – Takes a string as parameter and returns its length. Can count up to 500 in length.
  | group2 = By checking
  | list2 =
  {{Aligned table |fullwidth=on |style=text-align:left; |col1width=50%;
    | {{Aligned table |style=padding-right:2.5em;
      |col1style=width:12.5em;text-align:right;white-space:nowrap;padding-right:0.75em;
      | {{tl|trim}}                | To trim any leading or trailing whitespace
      | {{tl|str letter/trim}}    | To trim down to the beginning letters.
      | {{tl|str number/trim}}    | To trim down to the beginning numbers.
      | {{tl|trim brackets}}      | To trim any leading or trailing square brackets.
      | {{tl|trim quotes}}         | To trim leading or trailing matching quotes.
      }}
    | {{Aligned table
      |col1style=width:12.5em;text-align:right;white-space:nowrap;padding-right:0.75em;
      | {{tl|first word}}          | To trim down to the first space.
      | {{tl|remove first word}}  | To remove anything before the first space.
      | {{tl|last word}}          | To trim down from the last space.
      | {{tl|remove last word}}    | To remove anything after the last space.
  }} }}


Technical stuff:
  | group3 = Dedicated
  | list3 =
  {{Aligned table |fullwidth=on |style=text-align:left; |col1width=50%;
    | {{Aligned table |style=padding-right:2.5em;
      |col1style=width:12.5em;text-align:right;white-space:nowrap;padding-right:0.75em;
      | {{tl|delink}}, {{tl|trim brackets}}              | Removes wikilink brackets (wikicode); ''all'' or ''outer only''.
