Do universes come in a whole load of different sizes?

Do universes come in a whole load of different sizes, in the same way that planets and stars and galaxies do?
Are there some really small universes out there, where sentient beings similar to ourselves are not baffled by the size of that universe, because isn't actually all that big?
Maybe there are one or two universes out there that are just big enough for family of four?
Maybe we could move in?
