Is England the same land size as New Zealand?
Well, New Zealand, Japan, and the UK/GB are often compared for size. The numbers are:-
England, 130 395;
Great Britain 229 848;
United Kingdom 243 610;
New Zealand 268 021;
Japan 377 944.
All numbers are in sq km.
There is no country directly on the other side of the world to England. That would place you in the ocean, somewhat southeast of New Zealand. The northern island of New Zealand is directly opposite of Spain. Australia is directly opposite the north Atlantic, and does not overlap with any land of significant size.
