Oops, I miscalculated. The added effort for the attacker if she does not know the password length asymptotically approaches (b+1)/b, where b is the size of the character space. Worst case for the attacker is a numeric password, which adds only a measly 11 % of effort. Lower-alpha gives 4 % more, etc.
