What Is a Style Sheet in Editing and Why Does Your Book Need One?

A style sheet in editing is the record a copy editor keeps of the decisions made on a manuscript: spellings, punctuation, capitalization, character details, and timeline. It keeps the book consistent with itself, and it lets everyone who works on the book after the editor follow the same choices. If you are self-publishing, ask your editor for it by name.

What Is a Style Sheet and How Does It Differ from a Style Guide?

A style sheet is a reference document built for one particular book. Copy editing, the stage it comes out of, is the pass that fixes spelling, grammar, punctuation, and internal consistency once the writing itself is settled. The Chartered Institute of Editing and Proofreading defines the sheet in its editorial glossary as a detailed record of the variable spellings, hyphenation, and capitalization used in a document. Variable spellings here means words with more than one correct form, not mistakes. In practice a sheet for a novel goes wider than that definition, and covers characters and settings too. Our breakdown of developmental editing, copy editing, and proofreading explains each kind of edit, from structure down to the final check, and shows where the style sheet arrives in the production timeline.

How a Style Guide Differs

A style guide is a different object from a style sheet. It sets broad rules for a whole category of writing rather than for your book, and it exists before your book does. The Chicago Manual of Style, the AP Stylebook, and the Publication Manual of the American Psychological Association are style guides. A style sheet records how those rules, and any deliberate departures from them, apply to your manuscript.

Think of the style guide as the law of the land and the style sheet as the local ordinances. Chicago’s general rule on numbers, for example, is to spell out one through one hundred, and it offers an alternative rule, numerals from 10 upward, for writing that carries a lot of figures. Your style sheet records which of the two your book follows, and any exception you make on purpose.

What Goes on a Copy-Editing Style Sheet?

Editors can organize a novel’s style sheet into six kinds of entry: references, spelling and usage, author preferences, character details, timeline and setting, and specialized terms and world-building. The exact format varies by editor, and a nonfiction sheet swaps two of them, character details and world-building, for terminology and citation style (how sources are referenced).

References, Spelling, and Author Preferences

References and governing style. The references section names the style guide the book follows, the dictionary it defers to when spellings differ, and any genre-specific references. A book that writes about disability, age, race, or other identities may also name a specialist reference for those word choices, such as the Conscious Style Guide. Chicago recommends Merriam-Webster as its dictionary while allowing for regional variation. So the dictionary should match the variety of English the book uses. Which variety that is, American or British for example, is a decision for you and your editor to settle, and it shapes many of the spelling entries that follow.

Spelling, punctuation, and usage choices. Often the longest section. It records whether you use the serial comma, the comma before “and” in a list of three or more. Dashes and their spacing belong here too, along with whether you write “okay” or “OK.” It also records each word with more than one accepted spelling that came up in the edit. A single inconsistent hyphen is nothing on its own, but a book full of them reads as unchecked.

Author preferences and exceptions. Deliberate rule-breaking, stylistic choices you have told the editor are intentional, and notes on voice or tone that should be preserved rather than corrected.

The Word List

A style sheet should also have a separate word list: an alphabetical record of proper nouns (the names of people, places, and things), unusual terms, and every word whose spelling or treatment needed a decision. If your novel has a character named Caelynn (not Kaelyn, not Cailynn), she goes in the word list. If your nonfiction book writes “health care” as two words rather than “healthcare,” that goes in as well. Writing for the Chartered Institute of Editing and Proofreading on creating style sheets for fiction, editor Jane Hammett calls the word list essential for every job. Her reason is practical: an editor will not remember a spelling chosen on page 5 when the same word turns up again on page 505.

Character, Setting, and World-Building Entries

A novel’s style sheet records character details: names, including spelling variants and nicknames, plus physical descriptions, ages, relationships, occupations, and speech patterns. Editor Jane Hammett’s worked example shows the level of detail that helps an editor keep a character consistent: “Skye (age 14 at end of Book 1, born May 2009). Appearance: short dark brown hair, 5 foot 4, scar over right eye, brown eyes.” An entry like that is what catches brown eyes turning blue in chapter twenty.

Timeline and setting. Key dates, seasons, time-of-day references, place names, and distances. This is the section that catches a journey taking two hours in chapter three and thirty minutes in chapter twelve.

Specialized terms and world-building. Invented words, technical jargon, foreign phrases, and any terminology unique to your book. Fantasy, science fiction, and historical fiction tend to fill this section; a contemporary novel may barely use it. If your fantasy novel capitalizes “the Sight” as a proper noun but leaves “the darkness” lowercase, that distinction belongs here.

What Changes for Nonfiction

A nonfiction style sheet has the same references, spelling and usage choices, author preferences, and timeline entries as a novel’s. But in place of character and world-building entries it records terminology, including abbreviations, and citation style. A book on medical topics needs every drug name, condition, and procedure spelled and capitalized the same way throughout; a history book needs consistent date formats and consistent names for historical figures.

Naming the Edition of the Style Guide

A style sheet should name the edition of the style guide the editor worked from, because a new edition can reverse an old rule. The Chicago Manual of Style is now in its 18th edition, published in 2024. That edition added a manuscript-to-book outline aimed at self-publishers and changed several rules that earlier editions settled differently. Chicago lists every change on its What’s New in the 18th Edition page.

Among the changes likely to touch a self-published book, Chicago now endorses the generic singular “they” for a person whose gender is unknown or unspecified, and it capitalizes the first word of a complete sentence after a colon. It writes “ebook” as one word, and it uses an apostrophe to form the plural of a capital letter. It also capitalizes prepositions (words such as about, between, and through) of five letters or more in titles. So “About” takes a capital in Much Ado About Nothing, while “with” stays lowercase in A Room with a View.

Two more changes concern fiction in particular. Words from another language used by a multilingual narrator or character no longer need italics. Whether to italicize them is now a choice worth making deliberately rather than leaving to habit. And Chicago added guidance on fictional dialogue, including speaker tags (“she said”), interrupted speech, quotations within dialogue, thoughts set in italics, and text messages on the page. Whichever conventions your book follows in those places become style sheet entries.

Silent Changes and Notes for the Formatter

A style sheet serves the formatter (sometimes called the typesetter), the person who lays out the book’s pages. Jane Hammett’s article says the sheet should list any silent changes: corrections the editor made with Track Changes switched off. Track Changes is the feature in Word and similar programs that marks every edit. The sheet should also list any notes the editor has left in the file for the formatter. Silent changes leave no mark in the file, so that list is the only record of them.

How Is a Style Sheet Created and Used?

A copy editor builds the style sheet while working through the manuscript. Every time a choice comes up, they record it: how to spell a character’s name, whether a job title takes a capital, how to set a date. When the same question returns later in the book, the sheet answers it.

The finished sheet is usually a word-processing document or a spreadsheet, arranged alphabetically or by category. Despite the shared name, it is not the “styles” settings in Word or the style sheet behind a web page.

Where the sheet earns its keep is the handover. After the edit, the formatter lays out the pages. As they work, they decide whether an unusual spelling or an odd capital is a choice to preserve or an error to query (raise as a question with you). A sheet that specifies British spelling, for example, tells the formatter that “colour” and “realise” are deliberate. When the style sheet records the choice, the decision takes seconds. When it does not, the file comes back to you with queries, sometimes about words your editor settled weeks earlier.

Proofreading is the final check, made on the laid-out pages, so the proofreader reads your book in the form a reader will see it. The Chartered Institute of Editing and Proofreading’s glossary, which says copy editors should routinely compile a style sheet, adds that the proofreader may receive the sheet, so they can see which style the text should follow consistently. Working from it, they can tell a deliberate choice from a slip, and they are far less likely to reverse a decision made on purpose.

Using the Style Sheet Your Editor Returns

When your edited manuscript comes back, the style sheet should come with it as a separate document. Treat it as the master reference for every stage that follows. If you are reviewing your editor’s tracked changes, the sheet explains the systematic ones. If your editor changed every “OK” to “okay,” for example, the sheet records that decision, so you can see it was one choice applied throughout rather than a string of separate edits.

When you send the book for formatting, send the sheet with it. If you also hire a proofreader for the laid-out pages, send it with the pages too.

Why Should Self-Published Authors Hold On to the Style Sheet?

A self-published author holds a thread that a publisher would otherwise hold for them: continuity between the freelancers who work on a book, which the style sheet records. Publishers use freelance copy editors and proofreaders too. The difference is that somebody in-house passes the style sheet from one to the next. And when you self-publish, that somebody is you.

When each new professional starts from your sheet, the work takes less time, which can mean a lower price or a more thorough edit inside the same budget. Your voice stays where you put it, too.

The sheet also outlives the book it was made for. Many of the decisions on it belong to you as a writer rather than to one story. They include the variety of English you write in, whether you use the serial comma, how you treat numbers, which words you capitalize, and how you set characters’ thoughts or text messages on the page. When you start your next manuscript, you have already made those decisions.

If the next book is in a series, it takes over the whole sheet, characters and world included. If it is a standalone book in the same genre, the general entries still carry over. And over several books they become your own house style (the conventions a publisher applies to every book it publishes). Your books then stay consistent with one another as well as within themselves.

How Can You Create a Basic Style Sheet Before Hiring an Editor?

You can write the first version of a style sheet yourself, before you hire an editor. The Chartered Institute of Editing and Proofreading’s fact sheets page links to its free guide for authors, Proofreading or Editing? A Quick Guide to Using Editorial Professionals. The guide tells authors who work with an editor to check their text against the editor’s style sheet, and otherwise to compile one themselves. A post on the blog of ACES: The Society for Editing makes the same point from the editor’s side. Its author, an editor, writes that receiving a style sheet from an author is extremely helpful, because it means fewer questions about why the author chose a spelling or a format.

What to Put in Your First Draft of the Sheet

Begin your own style sheet with a document divided into the same kinds of entry an editor uses, and fill in what you already know.

• References. The style guide you prefer, if you have one, and the dictionary you use.
• Spelling and usage. Words you have consciously chosen to spell or capitalize a particular way.
• Deliberate choices. Places where you break a rule on purpose, such as sentence fragments or dialect in dialogue.
• Characters. Names, nicknames, and key physical details.
• Timeline. The dates, seasons, and time references your manuscript depends on.

You do not need to catch everything, because completeness is the editor’s job. What matters most, though, is marking which choices are deliberate, so your editor does not standardize them and then have to put them back. It helps to flag the opposite as well: habits you know you have and would welcome a firmer hand on, such as words you overuse or grammar patterns carried over from a first language. Attach the sheet as a separate file when you send the manuscript over.

Treat your first draft as a starting position rather than an instruction. Your editor may have good reason to depart from a preference you listed, particularly where it would confuse readers or cut against the conventions of your genre. Expect the returned sheet to differ from the one you sent, and expect your editor to explain the differences.

How Does a Style Sheet Prevent Series Continuity Errors?

A style sheet becomes hard to do without once you write a series. A character’s eye color changes between books. The sequel spells the name of a town differently. An invented technology works one way in book one and another way in book three. Any of those can pull a reader out of the story, and every new volume adds chances for them.

The sheet carries forward. After book one it holds every character name, physical description, location, timeline event, and world-building rule. Before the edit on book two begins, you send the editor the current version to work from and add to. By book five it covers the whole series, and Jane Hammett calls this accumulated version a series style sheet.

Editor Carolyn Haley, writing on the editors’ blog An American Editor, calls building a comprehensive style sheet “the most important part of editing a series.” Her reasons are that months or years may pass between volumes, and different editors may work on different books. She adds an instruction that is easy to miss. Before an editor begins work on a later volume, you, or whoever hired them, need to confirm one thing. Will they start a new style sheet for that book, or add to the one that already travels with the series? Left unasked, that question can leave a series with several partial sheets that disagree with each other.

When the Editor or Formatter Changes Partway Through a Series

When a new editor takes over a series at book three, a series style sheet tells them, for example, that a protagonist’s mother is “Eimear” and not “Eimer,” or that a fictional city called Vael-Kirin takes a hyphen. For an editor who joins a series with no style sheet, Carolyn Haley’s advice is to ask for copies of the earlier books and to build extra time into the quote. That time goes on tracing each style point back through the earlier books, so the new volume can match them.

A formatter meets the same kind of drift when a series changes hands or spans several years. For example, a character’s name gains an accent in book two, or an invented unit of currency changes spelling. Each one is fixable, but fixing it means asking you which form you intended. And a running style sheet saves that round trip.

A style sheet records your book’s settled decisions and travels with it from copy editing to the final proofread. Start a rough version before you hire anyone, ask for the finished sheet when you agree on the work with your editor, and send it on to whoever formats or proofreads the pages. For a series, keep adding to the same document rather than starting a new one for each book.

Frequently Asked Questions

Should I ask my editor for a style sheet if they do not provide one?

It is worth asking your editor for a style sheet, and worth asking when you agree on the work rather than when the edit comes back. The Chartered Institute of Editing and Proofreading’s editorial glossary says copy editors should routinely compile one, and The Copyeditor’s Handbook covers style sheets among the basic procedures of copy editing, so it is a reasonable thing to expect. Asking at that point is what turns it from an assumption into part of the job. If no sheet comes back, you can build one from the edited manuscript by noting its spellings, capitals, and hyphens, but that takes time.

Can I use the same style sheet for every book in a series?

One style sheet can serve every book in a series, and that is where it is most useful. The sheet carries forward, and each book adds character details, world-building rules, and editorial decisions to it. Keep the master copy yourself. Send the current version to whoever edits, formats, or proofreads the next book, so they can match the earlier volumes without re-reading them.

What is the difference between a style sheet and a character bible?

A character bible is a writer’s reference to their characters: descriptions, backstories, relationships, and arcs. A style sheet is an editing record. Its character section overlaps with a character bible but holds only what consistency needs, such as names, physical details, ages, and relationships, alongside the spelling, punctuation, and timeline decisions for the whole book.

How long should a style sheet be?

A style sheet has no fixed length, because it follows the number of decisions the manuscript raises. A straightforward contemporary novel might produce one or two pages, and a novel with a large cast and an invented world needs more. What matters is that each entry records a real decision: editor Jane Hammett, writing for the Chartered Institute of Editing and Proofreading on style sheets for fiction, warns that it is easy to get carried away. She adds that a sheet several pages long is not always the most useful one for the author.

Do I need to follow The Chicago Manual of Style for my self-published book?

You do not have to follow The Chicago Manual of Style; it is a guide, not a requirement. It was written for book publishing, though, so it gives you, your editor, and your proofreader a shared starting point. And any deliberate departure from it is exactly what your style sheet records. For a book in British English, the New Oxford Style Manual covers similar ground.

Which edition of Chicago should my style sheet name?

Your style sheet should name whichever edition of The Chicago Manual of Style your editor actually worked from, because editions change rules. The 18th edition, published in 2024, reversed several rules that earlier editions settled differently, and Chicago lists every change on its What’s New in the 18th Edition page. A sheet that says only “follows Chicago” leaves your proofreader guessing which set of rules applies.

Can I use a style sheet template instead of creating one from scratch?

A template is a good starting point for a style sheet, because a structure keeps you from overlooking a standard entry such as spelling and punctuation, the timeline, or the word list. Editor Jane Hammett’s article for the Chartered Institute of Editing and Proofreading on creating style sheets for fiction sets out what to include, and editor Amy Schneider’s four-part series on the editors’ blog An American Editor works through general style, characters, locations, and timeline in turn. Fill the structure in with your own manuscript’s decisions rather than treating any template as finished.

Should I update my style sheet if I revise my book after publication?

Revising a published book is a reason to update its style sheet. A revision that renames a character, adds invented terms, or changes a spelling convention creates new decisions, and they belong on the sheet. Months later, the sheet is also what tells you how you spelled a minor character’s surname, so a revised edition or a new book in the series starts from the right list.
