PDB Files
Text sizes are simplest for PDB files. The five sizes are the same from file to file. Medium in one
eBook is the same as Medium in the next one. The other sizes are the same as well.
When you change the Reader text size in a PDB file, your NOOK repaginates the content. It can
take up to several minutes before your NOOK displays the progress bar and page numbers.
For PDF files in some foreign languages, your NOOK is not able to resize the fonts. For
these, you will see one size (Small).
EPUB Files
EPUB files can contain instructions that specify the size of body text and other text, for example
chapter titles.
When displayed, the text of digital content in EPUB, PDB, and reflowable PDF documents is in
one of five sizes. For most digital content, medium will be medium will be medium (the same size
medium). The other sizes will be the same as well. But there are exceptions to every rule. In some
cases, the fonts will be larger than usual, and in other cases smaller. In these cases, you should still
be able to choose a text size that works for you.
In Settings, the sizes are identified as Extra small, Small, Medium, Large, and Extra large. Other text
in digital content, for example, chapter and section headings, is also sized proportionally based on
the choice of Reader text size.
Changes in the text size only aect the Reader. They do not change the size of text in The
Daily, Shop, library, or settings. They also do not change the size of text in the touchscreen
menus.
Here are examples of the text sizes Extra small, Medium, and Extra large for the font Amasis.
