It is 26 kilometres (16 mi) from Nuijamaa to the city center of Lappeenranta and 39 kilometres (24 mi) to the medieval town of Vyborg, Russia.

Before the Winter War, Nuijamaa had an area of 356 km2 (137 sq mi).

With the Continuation War in 1944, 220 km2 (85 sq mi) of the municipality was ceded to Russia.
