La forma más fácil:
$('#selector').val().length

JQuery es una biblioteca JavaScript.
No necesita usar jQuery para obtener la longitud de una cadena porque es una propiedad básica de objeto de cadena de JavaScript.
somestring.length;

No necesitas usar jquery.
var myString = 'abc';
var n = myString.length;
N será 3.

Una distinción algo importante es si el elemento es una entrada o no. Si una entrada se puede utilizar:
$('#selector').val().length;
De lo contrario, si el elemento es un elemento html diferente, como un párrafo o un elemento de lista div, etc., debe usar
$('#selector').text().length;

En jQuery:
var len = jQuery('.selector').val().length; //or
( var len = $('.selector').val().length;) //- If Element is Text Box
O
var len = jQuery('.selector').html().length; //or
( var len = $('.selector').html().length; ) //- If Element is not Input Text Box
En JS:
var len = str.len;
