If you change the length of fields between testing and production, it would
invalidate your boundary testing! What if there is a bug in your code that
presents itself when a field is 200 characters, but not when it is 50
characters long? There is no difference in disk usage with the example you
gave, so I can see no reason to have different lengths for varchar fields
between test and prod environments.
