Best PDF size (width x length) for mobile device?

I need to create a printed brochure that is also easily readable on smartphone and other mobile devices. In terms of size, is there a best size (width x length) or aspect ratio for mobile devices?

Can a PDF be optimized in some way to make it easier to view without excessive zooming on a mobile device?

Thanks!

It doesn't really matter. Almost all PDF viewers will scale the file to fit the screen size.

What if I don't want a person to be allowed to scale the document? I'm trying to design a document for mobile so any automated optimization will ruin the design and structure.
