Depends what country - nuclear A-bombs used to be deployed from planes (they still are, just not as much). H-bombs tend to be ICBMs (Inter-Continental Ballistic Missiles) - basically huge rockets tipped with one or more nuclear warheads.
Size? Again, depends what country - the USA, Russia and China probably have nukes that could reach any country. Britain, France and possibly Israel have weapons that could probably cross half the globe and cause significant damage. Countries like North Korea, India and Pakistan have short-range warheads with lower yield (in the kilotons).
