How to format a book interior
What separates a typeset book from a Word file printed to PDF — mirrored margins, real hyphenation, chapters that open on the right, running heads that know when to vanish, and a page count the printer will accept.
Type size, leading and the line that reads well
Three measurements decide whether a page is comfortable — the size of the type, the distance between baselines, and the length of the line. They pull against each other, and every one of them changes your page count.
What goes in the front of a book, and in what order
The pages before chapter one follow a settled order, and readers notice when it is wrong even if they can't say why. What each page is for, why the blanks are deliberate, and what a copyright page has to carry.
The large print edition most authors never make
A large print edition is a separate product with its own ISBN, cover and listing, sold to an audience that is real, underserved, and includes libraries. What actually makes a book large print, and what it costs you.
Indents, spacing, and how paragraphs should start
A blank line between paragraphs is the single most reliable sign that a book was typeset in a word processor. What a real indent is, how deep it should be, and why your manuscript should not contain a single one.
Workbooks, journals and books people write in
A workbook is not read, it is used, and every design decision changes because of it. Room to write, lines light enough to ignore, paper that survives a pen, and a binding that stays open.
Parts, sections and the pages between chapters
Long books are divided, and the divisions need pages of their own. What a part title is, what each one costs in paper and spine width, and why the loudest page in your interior should be quieter than you think.
Quoting other people's work in your book
Authors drop a lyric, a stanza or a favorite paragraph into a manuscript without a second thought, and some of them hear about it later. Which quotations carry real risk, which are generally safe, and how permission actually works.
Justification, hyphenation, and the gaps between words
Justified text in a word processor and justified text in a book are made by two different methods, and that is why one has even color and the other has loose lines. What decides the gaps, and what you actually control.
Blank pages, recto and verso, and why the count is even
Your proof arrives with pages you did not write. They are correct. What recto and verso mean, why a bound book always has an even page count, and the one lever that decides how many blanks you get.
Glossaries, appendices and other back matter
The material that belongs after the story or the argument, and how to set it so a reader can actually use it. Order, type size, hanging indents, and the fantasy glossary that gives the ending away.
Field guides and reference layout
A field guide is opened in the middle, not started at the beginning. What that one fact does to running heads, to the entry template, to where the pictures sit, and to the trim you can carry.
Letters, texts and documents inside a novel
A letter, a diary page, a clipping, an email, a text exchange, a prophecy on a scrap of vellum. How to set an inserted document so the reader registers the change of voice before reading a word, and what survives a page break.
Sidebars, boxes and pull quotes
The devices that break up a nonfiction page, and the discipline that stops them wrecking it. What a sidebar is for, what a pull quote is for, why the two rules are opposites, and how many a page holds.
Printing music and notation
Songbooks, hymnals, method books and novels with four bars in them are three different production problems. Why you engrave elsewhere and place the result, what resolution and trim size that forces, and the page turn that governs the layout.
Puzzle and activity books
Crosswords, sudoku, word searches, mazes and activity pages have production rules of their own, because the reader writes in the book. What that does to grid size, trim, paper, the solutions section and the binding.
Maps and diagrams inside a book
A map is the illustration fantasy, history and technical readers actually want, and the one most often ruined in production. Where it goes, why the gutter eats a spread, and how to size labels for a printed page.
Timelines, family trees and other structured diagrams
Sagas, histories and biographies need reference diagrams, and every one of them is wide while a book page is tall. The four honest ways to fit one, the type rule that decides which you pick, and the spoiler trap.
