How do I edit in full screen

I can’t seem to resize the screen I am working on. I have my images however I don’t want to zoom I want to expand the screen and work on the details. My scale is 0.46 putting it higher will just zoom me in. How can I expand my screen? Thx all

? The same as you resize any other window - move your mouse cursor to a corner until the icon changes to this:

Then click and drag to resize the window.

You can drag your game Window out of Unity, just like you can drag it around into some other place. Therefore you can make it fullscreen and you can switch between your Unity windows and your Game Window.
