Own note 5, thinking about getting the 8 inch tab s2 for textbooks

Hey guys I was hoping for some help. I own a Note 5 but for school I was hoping for something smallish for textbooks. I was reading that the actual screen size of the 8.0 was actually just 6.5 by 5 inches. Is that accurate? If so would you say that the difference for reading textbooks would be almost redundant size wise between the note 5 and galaxy tab s2 8.0 screen?
