Is “To” Capitalized in a Title? Complete US Style Guide
Is “To” capitalized in a title? Learn US title capitalization rules for “to,” with AP, Chicago, MLA, and APA examples to write titles correctly every time.
I have stared at a title I just wrote and wondered if that little word “the” should really be capitalized or not. I am not alone. Getting title capitalization trips up even seasoned writers. The US style rules feel more confusing than they need to be.
If I have ever typed a headline and paused, wondering if “to” is capitalized in a title, I am asking the question at the right time. The short answer is: it depends on where “to” sits in the sentence and which US style guide I am following. Let us break it all down so I never have to guess a title again.
Why Title Capitalization Rules Actually Matter
Before we get into the specifics, it helps to understand why title capitalization rules even matter. A properly capitalized title looks polished, professional, and trustworthy. A poorly capitalized one can make even great writing look sloppy or rushed. Whether I am publishing a blog post, formatting a book title, or submitting a manuscript, capitalization is one of those details US readers notice, even if they cannot explain why something looks “off.”
At Book Publishing Forge, they see this constantly with authors. Someone spends months writing a manuscript, then trips over the title page formatting. It is a fix once I know the rules.

The Basic Rule: Which Words Get Capitalized
Most US style guides like Chicago, AP, APA, and MLA agree on the main points, even if they differ on smaller details.
Here is the general pattern:
Always Capitalize:
- The first word of the title
- The last word of the title
- All nouns, pronouns, verbs, adjectives, and adverbs
- Subordinating conjunctions like “because,” “although,” and “if”
Lowercase, unless first or last word:
- Articles, such as a, an, and the
- Coordinating conjunctions, such as but, or, nor, for, so, and yet
- Short prepositions, such as in, on, at, by, up, and off
This is where title case capitalization gets its structure. It is not random; it follows a logic based on the weight of each word. This is the standard every US publisher, newsroom, and academic journal sticks to.
Is “To” Capitalized in a Title?
Here is the part everyone actually wants answered. The word “to” causes confusion because it can function in two ways in English:
- As a preposition, like “I went to the store”
- As part of a verb, like “I want to run”
Under most US style guides, “to” is treated as a short preposition and stays lowercase in the middle of a title. So “How to Capitalize a Title” keeps “to” lowercase, even though “Capitalize” gets capitalized.
However, APA style is stricter. It capitalizes prepositions of four letters or more. So under APA rules, some longer prepositions get capitalized where AP or Chicago would not. “To” itself, being two letters, almost always stays lowercase across every major US style guide unless it starts or ends the title.

A Quick Comparison Table of US Style Guides
| Style Guide | Articles (a, an, the) | Short Prepositions | Coordinating Conjunctions | First/Last Word |
|---|---|---|---|---|
| Chicago Manual of Style | Lowercase | Lowercase | Lowercase | Always capitalized |
| AP Style | Lowercase | Lowercase, unless 4+ letters | Lowercase | Always capitalized |
| APA Style | Lowercase | Lowercase, unless 4+ letters | Lowercase | Always capitalized |
| MLA Style | Lowercase | Lowercase | Lowercase | Always capitalized |
Notice the pattern: every US style guide treats short prepositions and articles the same way. The differences show up with longer prepositions and how strictly the “four-letter rule” gets applied.
Title Capitalization Examples I Can Copy
Sometimes the way to understand a rule is to just see it in action. Here are a few title capitalization examples across sentence structures:
- How to Write a Book in 30 Days
- The Art of Storytelling for Beginners
- Why Self-Publishing Is Growing in Popularity
- A Guide to Getting Published Without an Agent
- What to Expect When Working With a Ghostwriter
Notice how “to,” “a,” “in,” and “for” stay lowercase throughout while the meaningful words carry the capital letters. This pattern is what gives titles that professional look that US readers expect from published work.
Using a Title Capitalizer Tool
If all of this still feels like a lot to keep track of manually, I am in good company. Most professional writers do not memorize every rule. They lean on a title capitalizer tool to handle the formatting. These tools apply the US style guide of my choice, like Chicago, AP, APA, and MLA. It instantly converts my title into the correct case.
This is especially useful when I am formatting a lot of headlines at once, like for a blog, a portfolio of book titles, or a manuscript with chapter headings. It saves time and removes the guesswork so I can focus on the writing instead of second-guessing every “the” and “of.”
Common Mistakes Writers Make With Title Case
Even careful writers slip up sometimes. Here are the common errors:
- Capitalizing every single word, including small articles and prepositions
- Forgetting to capitalize the first word of the title, even if it is short
- Mixing rules from two US style guides in the same document
- Capitalizing “is,” “be,” or “are” inconsistently. These verbs should always be capitalized
- Applying sentence case, only capitalizing the first word, when title case was intended
If I have made any of these mistakes before, I should not worry. It happens to everyone at some point. The good news is that once the rule clicks, it is hard to unlearn.

How This Applies to Book Titles and Manuscripts
For authors working on a manuscript, cover design, or query letter, title capitalization is not a stylistic nicety; it is part of looking professional to US agents, editors, and readers.

This is something the team at Book Forge pays attention to when helping authors prepare their manuscripts for submission or publication. Small formatting details like this add up to a final product.
