As you continue to develop your content, target your market, and research self-publishing options, it will become at some point important to consider your book length.
The most important thing to recognize is the difference between your manuscript page size (which is most likely 8.5 x 11) and your published book trim size (which will most likely be smaller). Whenever a publisher discusses page count, or per-page pricing, it is based upon the size of the published page.
The most common published book trim sizes are 5.5 x 8.5 and 6 x 9, although many publishers will offer several more options. Check out our recent post on book sizes recommendations for more on choosing your book’s trim size.
If your manuscript is 100 pages long at 8.5 x 11, you probably have closer to 200 pages of finished text when the book is published. The good news is, your book just got twice as long, which in many cases improves its perceived value. On the other hand, some authors will be surprised when they see pricing based upon 200 pages instead of 100. Be prepared.
Keep in mind that production cost is directly related to page count, and POD books, as a result of their many advantages, are still a bit higher per-book than traditionally offset printed titles. The more pages your book has, the more it will cost to print. Most authors keep their books between 100-300 published pages.
