how to make default format go past 6"

I know how to make a defaul editor set up. I just want to know if there’s a way to go way over 6 on the ruler. I’m having a hard time finding information about Scrivener for windows as most if not all the tips and advice i see are for Mac.

You just need to expand the window to make it wider, then it will show more of the ruler. The same is true for an Editor window. Generally there is no need to set the right margin. You can control the line length displayed in the editor by changing the size of the editor window and adjusting the Editor Margin, which is set just below the area of your screen-shot.
