How to Format Chapter Headings and Numbers
How to format chapter headings, numbers, and titles consistently in a book, and how to choose between numbered and titled chapters.
Chapter headings are the signposts of a book. Every time a reader reaches one, it tells them where they are and gives the story a moment to breathe. Because they repeat throughout the book, they are also where inconsistency shows up most: a heading that is centred in one chapter and left-aligned in the next, or numbering that goes wrong after an edit. This guide covers how to format chapter headings and numbers so they stay consistent and look intentional.
The parts of a chapter heading
A chapter heading is usually made from up to three parts: a chapter number, a title, and sometimes a subtitle. You can use any combination. Fiction often uses a number alone, non-fiction usually uses a descriptive title, and plenty of books use a number and a title together. Decide which parts your book uses, then apply that choice to every chapter without exception.
Numbering that does not break
The most common chapter-heading mistake is typing the numbers by hand. The moment you add, delete, or reorder a chapter, the numbers are wrong, and it is easy to miss. The reliable approach is automatic numbering, where the tool numbers chapters from their order in the book. You choose the format once, usually words ("Chapter One"), numerals ("Chapter 1"), or roman numerals, and the numbering looks after itself.
Consistency is the whole job
What makes chapter headings look professional is not any single choice but the fact that every chapter is treated the same. The same wording style, the same alignment, the same size, and the same amount of space above and below. This is exactly the kind of thing that is tedious to keep consistent by hand across a whole manuscript, and effortless when one chapter design is applied to the entire book.
Formatting chapter headings in Koberger
Koberger applies one chapter design across your whole book, so every heading matches automatically. You choose a chapter-opening layout, decide whether to show the number, title, and subtitle, and pick how chapters are numbered, and Koberger numbers them from their order and keeps everything consistent as you edit. You can also add a drop cap to the chapter opening. Preview the result and format your book for free before you export.
Frequently asked questions
How do you format chapter headings?
A chapter heading is the number, title, or both that opens a chapter. Keep the style identical across every chapter: the same wording, size, alignment, and spacing. A formatter applies one chapter design to the whole book so you do not have to style each opening by hand.
Should chapters be numbered or titled?
Both work. Numbers alone ("Chapter One") suit most fiction; titles suit non-fiction and some novels; many books use both. The important thing is to be consistent, and to number automatically so inserting or reordering a chapter does not leave the numbers wrong.
How do you number chapters in a book?
Let your formatting tool number them automatically from the chapter order, rather than typing each number. That way the numbering stays correct if you add, delete, or reorder chapters. You can usually choose words ("Chapter One"), numerals ("1"), or roman numerals.
What is a chapter heading?
The chapter heading is the block at the top of a chapter that announces it, made up of some combination of a chapter number, a title, and sometimes a subtitle. It sets the tone for the chapter opening and, done consistently, is a big part of what makes a book look professional.
