[Maya] Grid went vertical, how do I make it horizontal again?

Exactly as title says. Here are my camera attributes after making a new camera. Y is set to up in settings.

Whew, I fixed it..

My grid was way too big. like 2048 units wide and lines every 256 units (meters). Going to Settings and making Y  or Z up did nothing because my grid was too big.. (?)

My fix--
-Make grid smaller (I did 256 meters wide, lines every 16 meters).
-Go to windows > settings/preferences > preferences > settings > click between Y up and Z up.
-Make sure your models are flipping onto their sides when you do this.
-Leave it on Y up.
-Reload your maya file. Grid should be horizontal again.
