1. The Old Empire was smaller than Leto's.
2. We have no idea how many planets/systems comprised the Old Empire, but the name "Million Planets" used by Scattering humans is suggestive. It is not known, however, if the name refers to all of the Old Empire, all of Leto's Empire, or simply that part of either located in the section of the Milky Way where the stories began.
3. Leto's Empire was definitely spread over more than one galaxy. The Old Empire at the time of
Dune may or may not have been. (I think not, simply because there is no clear statement to the effect that it was and based on other reasons discussed in the other thread. "May or may not" is my compromise position on this one.

)
4. If there's any validity to the Fishspeaker meeting scene measurements and narrative, Leto's Empire must have included at least somewhere close to 2.5 million planets.
I believe the above is consistent with the books, internally, and across the two threads, but I haven't reread the other thread.

There is a pretense estimate that during, or just after the C.E.T., the were 13,333,333 Worlds that had 1,000,000 religious followers or more. Or, more accurately, 6,000 is the estimate historians used to enumarate the number of human lives the riots took during/after the C.E.T. in each of the worlds then, in the Landsraad League?
Now, if riots happened also in worlds with less than 1,000,000 followers of religion? Wouldn't that means that there are even more planets than 13,333,333 Worlds?
What about if riots took part in Worlds that were not members of the Landsraad League?
We do not know if all the member Worlds had a religious following of any quantity.
13,333,333 Worlds in the Landsraad League.
