[2] The municipality (Gemeinde) of Grosselfingen covers 16.15 square kilometers (6.24 sq mi) of the Zollernalb district of Baden-Württemberg, one of the 16 States of the Federal Republic of Germany.

[2] Grosselfingen's municipal coat of arms is divided party per cross into four pieces, two black and two white.

This pattern is the coat of arms of the County of Zollern, but imposed on it are symbols in the white quarters.

In the upper left quarter are two zig-zag red lines, from the coat of arms of the House of Bubenhofen.

Called the "summer bird" (Sommervogel), this is a reference to the Honourable Court of Fools of Grosselfingen (ehrsame Narrengericht zu Grosselfingen), a local Fastnacht tradition that traces its origin to the rule of the Bubenhofens.
