We don't know that. We have no idea how big the Universe actually is.

If we extrapolate from the observable universe with the angles we can measure it should be at least 2.5 million times as big as the observable universe. At least. With no upper limit.

Or maybe we don't quite understand things as well and it is smaller.

Or maybe it is infinite.

We don't know.
