To capitalize, or not to capitalize, that is the question.
Every writer or blogger wants the "i's dotted, and t's crossed" while presenting their work. With capitalization in titles, you might get stumped on the word "to."
Here is the breakdown of how the rule works the rules to capitalizing "to" below.
Is "To" Capitalized in a Title?
Capitalization in titles depends on multiple variables. You need to keep them in mind when you use a title that includes "to".
Here's what you should ask when you capitalize your title:
Does "To" Come at the Beginning or the End?
Always capitalize the first word of your title, regardless of its grammar usage. In these cases, it doesn't matter if you're using "to" as a preposition, adverb, or infinitive.
On the other hand, title case style rules get tricky when "to" comes at the end of your heading. In these instances, your writing style determines the capitalization of titles.
Some writing styles require you to capitalize the last word of your title, while others don't have specific rules.
Example:
In the Beginning of a title:
- To Kill a Mockingbird
At the end of a title:
AP, MLA, Chicago, Wikipedia, and New York Times (always capitalize to)
- Top 5 Places to Fly To
- Why Everyone Needs Someone to Cry To
APA, AMA, and Bluebook (capitalization of titles determined by grammar function)
- 9 Things to Look Forward to
Is "To" a Preposition?
Grammar functions determine whether "to" will be capitalized or not. If you're using it as a preposition in a title, don't capitalize it.
Example:
- Let's go to the mall
This rule applies to all the writing styles (AP, MLA, Chicago, Wikipedia, New York Times, APA, AMA, and Bluebook).
What Happens When You Use "To" As an Adverb?
You need to capitalize "to" in titles when using it as an adverb. It usually happens when you're using expressions like "to and from" or as an adverb where it doesn't follow a noun.
Examples:
- Moving To a Goal
- When He Pulled the Door To
Bonus: The Case of the Infinitive
When you use "to" with a verb, it becomes an infinitive (to write, to be, etc.). In these cases, the writing style will determine the capitalization of your titles and headings.
If you're following AP style capitalization rules, you will use to + verb in uppercase. You will use lowercase for "to" in infinitives for the other writing styles.
Examples:
AP
- Nothing To Hide
- How To Grow Tomatoes in Your Backyard?
AMA, APA, Bluebook, Chicago, MLA, New York Times, Wikipedia
- Nothing to Hide
- How to Grow Tomatoes in Your Backyard?

In a Nutshell: It Depends
Capitalization in titles for "to" varies depending on how you use it and where it's placed within the heading.
You need to capitalize "to" when it's the first word of your title, used as an adverb, or as an infinitive (for AP style only). You also use uppercase for "to" when it comes at the end of your title while working on AP, MLA, Chicago, Wikipedia, and New York Times styles.
You don't need to capitalize it in all other instances, especially when you're using "to" as a preposition.
And remember you can always automatically capitalize your titles using our title capitalization tool.
One tiny word can slow down a whole draft. If you've ever paused mid-headline and thought, "Do I capitalize to?", you're not alone.
Here's the reliable answer for capitalize to in title questions on title case capitalization: in APA, Chicago, and AP title case, to is usually lowercase, unless placement or grammar forces a capital. The details are simple once you see the patterns.
The rule for "to" in APA style, Chicago Manual of Style, and AP style (and where each uses title case)
Before you decide on to, confirm the capitalization system you're using. APA style, the Chicago Manual of Style, and AP style do not apply title case in the same places. (MLA style, for comparison among major style guides, defaults to sentence case for most titles.)
For APA style's official rule wording from the Publication manual, see APA's title case capitalization guidance. For quick, practical summaries, these pages help: APA Title Case Rules 7th Edition and Chicago Manual title case rules. If you're writing headlines, keep AP Style title capitalization rules handy.
Here's the context that matters most:
| Style guide | What it typically uses for titles/headings | Where sentence case shows up most often |
|---|---|---|
| APA (7th, current in 2026) | Title case for paper titles, headings, table and figure titles | Sentence case for most reference list entry titles (articles, webpages, reports) |
| Chicago Manual of Style (CMOS, current editions) | Title case (headline style) for most titles and headings | Sentence case is more of a house-style choice, not the default for formal titles |
| AP (Stylebook, current editions) | Title case for headlines and many display titles | Sentence case is not the normal AP style headline approach |
Now, the rule for to itself:
- Lowercase "to" when it's a preposition under Prepositions ("Keys to the City") or the infinitive marker under Infinitive ("How to Edit Faster").
- Capitalize "To" when it's the first and last word of the title or subtitle in title case capitalization.
- Capitalize "To" when it's acting as an adverb (rare, but real), as in "Pull the Door To" (meaning "shut").
If you want a broader comparison of headline systems, AP vs Chicago title case differences gives a quick side-by-side, and this editor's overview of cross-guide quirks is also useful: title style capitalization breakdown.
If you're using title case and "to" sits in the middle, it's almost always lowercase. Position changes everything.
A 10-second checklist you can apply on any draft
Use this fast pass for capitalization rules when you're proofreading titles:
- First word? Capitalize it, even if it's To.
- Last word? Capitalize it, even if it's to.
- After a colon? Capitalize the first word of the subtitle, even if it's To.
- Middle of the title? Lowercase to (a preposition) in almost all cases; other parts of speech like nouns and verbs or pronouns and adverbs are typically capitalized. Some styles capitalize prepositions with four or more letters, which is why to remains lowercase.
- Is "to" an adverb meaning "shut"? Capitalize To (example: "Pull the Door To").
- Are you in APA references? Remember most titles in a reference list use sentence case, so you'll write something like "How to write a strong abstract" (only the first word and proper nouns get caps).
