How to set the size of string returned by PL/SQL functions?

Hi, I have created a PL/SQL function that return a VarChar2. I then call that function in a view to provide one of the columns in the view. The string that the function returns can never be longer than 15 character. When I run a desc on the view it shows function column as VarChar(4000). Can I change I define a size for the VarChar2 returned by the function?

I've looked in the docs and I must just not be thinking about it in the correct context.

Thanks,
