How do I get my Preview Window to be zoomed closer?

I have seen posts about zooming, and camera, and whatnot, and I apologize, I have not gotten that far into trying to set up my game. I am trying to prototype out a platformer like the Pico8, so I have 8x8 sprites, and for right now, I would like a 128x128 display, ultimately 640x480. However, when I press my Preview button, the game works, but man, is it zoomed out. I do not have any camera functions created or anything, this is just the default view it gave me when I ran my Preview. What is the method to get the Preview camera to be closer to the character? My Layout Editor zoom is fine, it is just the Preview that is too small.

Thank you for your time!

In the project properties bar you can change the viewport dimensions to whatever size you want.

Omg, thank you. I knew it was something stupid, and I apologize if you feel I wasted your time, but I could not figure this out - whether I should change the LAYOUT field, or the EDITOR field, or both, or if I had to set up a camera in the meantime. Ugh. Thank you.
