With a land area of 92,103 square kilometers, Hungary is roughly the size of the state of Indiana. It measures about 250 kilometers from north to south and 524 kilometers from east to west. It has some 2,258 kilometers of boundaries, shared with Austria to the west, Yugoslavia to the south and southwest, Romania to the southeast, the Soviet Union to the northeast, and Czechoslovakia to the north.

Hungary's modern borders were first established after World War I when, by the terms of the Treaty of Trianon in 1920, it lost more than two-thirds of what had formerly been the Kingdom of Hungary and 58.5 percent of its population (see Trianon Hungary , ch. 1). With the aid of Nazi Germany, the country secured some boundary revisions at the expense of parts of Slovakia in 1938 and Carpatho-Ukraine in 1939 and at the expense of Romania in 1940. However, Hungary lost these territories again with its defeat in World War II. After World War II, the Trianon boundaries were restored with a small revision that benefited Czechoslovakia.
