curious

my redo logs are 100m in size. how do i find the current size of redo log.
in other words:
> if i do a 'alter system switch logfile' and get a 40 m archived log'
how can i know the size (here 40m) before hand.
> or how to find the amount of 100m redo log that is used up, before
the redo fills to 100m.
