Easy to use and efficient string length comparison templates:

{{str ≥ len}} – To check if a string is "longer or equally long" vs. "shorter" than a given length.
{{str ≤ len}} – To check if a string is "shorter or equally long" vs. "longer" than a given length.
{{str ≠ len}} – To check if a string is "not equal" vs. "equal" to a given length.
{{str ≤ ≥ len}} – To check all three of "shorter", "equal" and "longer" at the same time.

Much less efficient string length template:

{{str len}} – Takes a string as parameter and returns its length. Can count up to 500 in length.
