This query seems to be a bit pessimistic on my test case, but is within 10%

select sum(bytes) bytes
from dba_segments
where owner = 'OWNER'
and segment_type not in (

   'CACHE',
   'ROLLBACK',
   'TYPE2',
   'UNDO',
   'INDEX'

)
/

The actual dump size is right about 5 gig.

The estimate from this script was 5.5 gig.
