Nook Book Size
Contents
Barnes & Noble, the second largest seller of eBooks as of the writing of this booklet (8-12% of the market monthly), has its own lines of e-readers, called Nooks. The Nooks come in B&W e-ink, like the Kindle, called the Nook Tablet, as well as a color model, called the Nook Color.
The Nook Tablet is 8.1” long and 5" wide. The screen, with a PPI (Pixels per Inch) resolution of 169, is 3.55” wide and just about 6” long, not dramatically different than the Kindle Fire Tablet.
The Nook Color is exactly the same physical size, and its screen size is also identical.

The Nook uses ePUB formatted books. This means that some advanced formatting is possible, like drop caps and images wrapped inside of text. Whoo-whoo! (update: in 2018, the KF8 Kindle eBooks are adequately advanced so that their capabilities and that of ePUB format are effectively indistinguishable.)
The Nook Color also has available a fixed-format ability, like the Kindle Fire, for children’s books in landscape mode. Moreover, it has “read along” capabilities, for audio files to read to children. (This should not be confused with the “text-to-speech” capability of the Kindles, which uses an automated voice. The read-along uses MP3 audio files.) The vertical page below is from the NookColor Tablet; the horizontal page is also from the NookColor tablet, but is from a proprietorially-formatted "ePIB" NookKids' books, which operates in "Fixed Format mode," so that text can display atop images, and show "spreads" (images that cross two pages) in the way that childrens' books should be read.

That's pretty much all to know, about the Nook devices.
