question on hyrdogen launchers

Consider the result of a decision that the fuel for the launcher must be
LH2. Given the necessary size due to the low density of LH2, is there a
point beyond which additional fuel is more than offset by the need for
additional support structure? How do things scale?

That is, is there in principal a maximum mass that can be launched with
LH2/LO2?
