In Phasmophobia, a medium map is one of the three different sizes of maps that players can investigate. As of October 2023, there are two medium maps available in the game: Prison and Brownstone High School. These maps are available to players once they reach level 10. Medium maps are denser and have more rooms than small maps, but are not as large as the two available large maps. The Prison, for example, has 25 rooms and three floors.
