It should be 1:1.
HOWEVER, it's more complex when you're talking about a complete
system. Data should usually be compressed before encryption and
there's normally framing and other added in the encrypted stream.
One drops the ratio, the other increases it.
Further complicating this is the possibility that a really
paranoid person will include frames containing random data.
(There will be some hidden marker indicating that they should be
ignored, of course.) It's hard to guess what's in an encrypted
file if they're always padded to a multiple of a megabyte or two.
