Specifying size for varchar2 output parameter

I've found that I need to compulsory specify size for any varchar2
output parameter. If i do not specify size I get foll exception:

Oracle.DataAccess.Client.OracleException ORA-06502: PL/SQL: numeric or
value error

Is there any workaround by which I do not need to specify size of
output parameter. I am asking this because of tommorrow the data size
of columns changes then the code also needs to be changed to adjust
the parameter size.
