I use Micro Soft Works word processor; on the initial page set up I have no idea how many pages this would translate into, but by clicking on file I found an area for page set up which, once it is set up, will be the approximate amount of pages contained in a book with this same trim size. For instance, I can set the page to 5.25 x 8 inches or 6 x 9 inches and a book with this same trim size would contain the number of pages I have written on my computer. Hope this helps.
