# Set Image Size and Page Orientation When Exporting to PDF [duplicate]

I want to export my plots (plot1 and plot2) as a pdf file. Since plot1 contains 4 figures in matrix form, so it will not fit in one page.

Export["plot.pdf", CreateDocument[Riffle[{plot1, plot2}, Cell["", "PageBreak", PageBreakBelow -> True]], Visible -> False]]

Here are my 2 questions:

1. How can I control the page layouts (e.g., landscape) when exporting to pdf file ?

2. Do we have to set the imagesize by ourselves all the time to make figures fit in one page ?
