[1] It is bounded by the village of Ratkovo on the north, Parage on the east, Tovariševo on the south, Deronje on the northwest and the town of Bač on the west and southwest.

[2] In the 19th century, the Imperial Austrian surveyors were sent to re-measure the area and to set the future look of the village.

They measured and marked the main and side streets, divided the area in the lots for housing, yards, churches and other public buildings.

[1] Hence, Selenča is a typical settlement of the Pannonian type, compact, square shaped, with the regular grid-like layout of the streets.

However, as the village grew, generally in the southwest–northeast direction, the non-planned building and expansion produced irregular street patterns on the periphery.

Total area of the village is 32.13 km2 (12.41 sq mi)[2] By the 2000s, there were still surviving the old, original houses, made from the wattle daubed with mud, with wooden roofs covered with reed.
