My main goal is to be able to see the full width of a "standard PDF page" at 100% zoom (as if I had printed it out.) So I guess by that metric I'm looking for a device which is at least 8.5 inches in one (or both) dimensions.
Then you need to pick your typical page, and look at it with different sized devices. Then you will know.
