How wide is the Universe?

Is the universe bound to be twice as wide across, measured in light year units, as it is old (measured in years)?

The universe is reckoned to be some 13 billion years old. Does it follow that it must be some 26 billion light years across?

(This would presumably be a result of spreading out in all directions at the same speed following the "Big Bang" ... See some musings about my state of growing ignorance in this posting at my other blog: Blissfully getting to know less about everything )
