  There is no theoritical limitation on the volume sizes. They could be fraction of micrometer.
  However, the number of volumes created could become a problem, if you wish millions of volumes.

  Almost all proposed examples do that. For instance, see:
  geant4/examples/extended/electromagnetic/TestEm4/SteppingAction
  or TestEm7 or any other ..
