A very common question we get asked is “what page/trim size should I use for my book?” There is a very simple (but useless) answer – there is no correct answer!
Now that I’ve got that out of the way, allow me to expand a bit 🙂
What I mean is that there is no “you must use this size” answer. There isn’t a formula where you plug in some numbers and get a result. All we can do is give you some guidelines, and then let you make the choice that feels right to you.
The four most common sizes used by indie authors are 5″x8″, 5.25″x8″, 5.5″x8.5″ and 6″x9″ (for reasons that will become obvious shortly). These aren’t the only sizes available in some situations (I’ll go into more detail about that later), but for most of the article, I’ll assume you’re trying to pick between one of these four sizes.
