Andong-si is the city with the largest area at 1,522 km2, followed by Gyeongju-si (1,325 km2) and Sangju-si (1,255 km2). On the other hand, cities in Gyeonggi-do are small in area. Guri-si is the city with the smallest area at 33.3 km2, followed by Gwacheon-si (35.9 km2) and Gunpo-si (36.5 km2).

For example, Suwon-si and Goyang-si, which have a population of more than 1 million, have areas of 121 km2 (71st) and 268 km2 (64th), respectively. These cities are relatively small in area compared to their population size.
