Amazon Kindle Direct Publishing: Interesting times:
Under the new payment method, you’ll be paid for each page individual customers read of your book, the first time they read it.
Of course, however, there are debates about what a “page” means, when it comes to ebooks.
To determine a book’s page count in a way that works across genres and devices, we’ve developed the Kindle Edition Normalized Page Count (KENPC). We calculate KENPC based on standard settings (e.g. font, line height, line spacing, etc.), and we’ll use KENPC to measure the number of pages customers read in your book, starting with the Start Reading Location (SRL) to the end of your book. Amazon typically sets SRL at chapter 1 so readers can start reading the core content of your book as soon as they open it.
