Newbie : PL/SQL Function Return value

Hi. I've just started working with PL/SQL and have defined functions that return a string. The problem is I'm creating a view using a whole lot of these type of functions, and the view ends up having a large number of varchar2(4000) fields. How can I force the function result to have a specific size if it is not based on an existing field type?

Thanks.
