    length($string) returns the number of characters in a string. 
    $foo = "quux";
$foolen = length $foo; # in this case, 4

    Since Perl 5.6, Perl has had Unicode support, which manifests itself as UTF-8 encoded strings. If you want to find out how many characters a string has, simply use length($string). It just works.

    However, if, for some reason, you need to find out how many bytes a string uses (which may be different from how many UTF-8 characters the string has): 

    use bytes;
my $len = bytes::length($string);

    Unless you know what you are doing, better steer clear of the latter. Use the former. (See perlunicode for more information.)

    Use the 'length' function

    For a variable $string Its length $stringlength can be found thus: 

    $stringlength = length($string);

    I would just like to add a word of thanks here. I used the syntax of this answer and applied it to the $buffer from a file read, and it worked. Cheers :D

    I prefer the use of brackets as well in this instance. For any beginers just starting out here's the code using brackets.

    
$someText = "Happy happy joy joy";
$someTextLength = length($someText);

    I found it difficult reading posts when I first started out because people were talking casually about stuff that was way over my head.I had no clue what they were on about, so I thought I would simplify this for any newbies

    its in my opinion easier to read code if you use length($foo) instead of length $foo but thats probably cause the first language i learned was JS
