How big is outer space?

How big is outer space? So logically we’d expect space to be 13.8 billion light years across, right? But the size of the observable universe is actually 46 billion light years, meaning the very first light we can see emitted (380,000 years after the Big Bang), came from a distance that is now 46 billion light years away.
