The Rules of Proper Book Formatting

After The Fractured Tree, I learned the hard way that a finished book isn't formatted like a manuscript draft, or a school essay. So what does a real book interior actually look like?

Three things, mainly, and each one fixes something a manuscript-style page gets wrong for print. Body text is justified, straight on both edges, not left-aligned and ragged the way a draft usually is. Paragraphs are marked with a first-line indent instead of a blank line between them, which is exactly what I got backwards the first time. And the trim size, the actual physical page dimensions, has to match a real book size: standard paperback trims run around 5x8 or 6x9 inches, not the oversized default a word processor exports at.

Where to start instead of guessing

Why does this trip people up in the first place? Because a word processor's default page setup is built for printing an essay at home, not for a printer producing a book, and nothing about it warns you it's wrong until the physical copy actually shows up looking off.

Most self-publishing platforms provide templates built to their required trim sizes already, so starting from one of those, instead of a blank document, avoids exactly the mess I ran into with The Fractured Tree, and saves you the unpublish-and-redo cycle I had to go through the hard way.
