Unity build resolution problem

I am making a 2d game. I have set my game screen resolution to a set size. I have an orthographic camera set up with a set size (this is the only camera active in the scene). When I play the game within the unity editor I play it in full screen and set the scaling to 1x and everything looks fine - The sprites line up with the edge of the screen and the game looks like it should. When I build and run the game the scene is zoomed out. My sprites that lined up with the edge of the screen sit in the middle and there is a bunch of empty world space around everything. Is there no way to construct the scene, play it and have that same thing shown when you build and run the game? I don’t know why this is happening and any help would be appreciated.
Thanks in advance.

Could you take a screenshot of your problem?
