If you have specific graphics on the page which are designed to fit a portrait or a a landscape, they may not transfer well.
Just remember the outrage people have over people not filming thing in landscape, because then one ends up watching a fullscreen video on pc that’s 80% black screen and only a sliver of actual footage on the screen, but we’re used to it.
The page layout is incredibly precise work for most things related to print, however if you’re just using PDF to relay text, it doesn’t really matter at all. But PDF is something you can have as print quality, so you work on a project, you make a PDF, then you take that PDF to the print and they print it in whatever size or colour, but the layout will be the same.
