Window Size

in the game I am making, I was having trouble lining up my menu objects on my screen, so I built and ran the game, and the window size was wrong, so I went and changed it in project settings, but when I rebuilt it, the window size was the same, so then I took those two builds and I ran them on another computer, they still had the same size as one another, but they are now very small.
I have no idea what could be causing this, I am doing nothing in my code to interact with the window in any way.
I have tested this multiple times while trying to change the window size and dimensions, but nothing works.

If anyone could offer some insight on this, that would be greatly appreciated.

I don’t know much about windowed games like that but I would recommend using fullscreen
