Looks different when compiled

When I work on a project in Scrivener, it shows as a two-page output

However, when I compile the project, it spits out a PDF that looks like this:. How do I fix this so that they both look the same?

When you c compile your pdf, what format are you using?

And what size in page setup are you using in composition mode?

If you want the 2 to match, you’ll need the page sizes to be the same for both. You may have to adjust your margins as well.
