A roughie (assuming your stats are up to date) would
be
select sum(num_rows * avg_row_len) * 1.1
from dba_tables
where owner in ( list to be exported )
added to
select sum(length(text))
from dba_source
where owner in ( list to be exported )
This doesn't take into account many things (view text,
lobs etc etc) but it gets you started...
