Chord pro files do not have a predefined size, and as of right now, they will always make use of all of the available space in the application window. Having said that, a user has requested the ability to override the dimensions for each page to more tightly control the rendered size of each page within the window. Once this feature is implemented, you could use this to force the page to be rendered to the aspect ratio and size of an A4 page, and that should make it easier to export to an A4 PDF or do whatever it is you need with an A4 sized page.
