Why is the Plate so Small And How can i Re-size it?

So The Little Thingy Where you can Place Your Objects in is SOOOO Little that i cant do anything, I Dunno how to re-size it back.

I Also Added a Normal Character Next to the Thing Where the Character Should Be

Its Almost the Same Size… ._.

Hi and welcome here :slight_smile:
Either you zoomed out your scene, and you can use the mouse wheel to zoom back in, either you picked a really small game resolution, and you can change that in Game settings/Properties.

Game Resolution, That was it, Thanks!
