100B LY is a little bit larger than the observable universe.
But the observable universe is a fraction of the whole thing. The "best guess" right now is that the total universe is flat and has no end.
If it's bounded, 100B LY is orders of magnitude below the most conservative lower-bound estimates, which I believe start at around 300-500x that size. (With huge error bars on all sides.)
