What Is Capitalized in Titles? | Title Case Without Guesswork

Title capitalization sounds easy until you hit a line like “to be or not to be,” add a subtitle, then drop in a hyphen, a quote, and a brand name. Suddenly you’re stuck on tiny words like in, to, and of.

This article gives you a clean rule set you can apply in seconds, plus the spots that cause the most edits: subtitles, hyphenated compounds, “to” in infinitives, and titles inside titles. You’ll also see how the common style systems differ, so your titles match the expectation in class, at work, or on a blog.

Title capitalization basics

Most English title styles split words into two buckets: major words and minor words. Major words get capitals. Minor words usually stay lowercase, except when they start or end the title.

Words that get capitals in most title styles

• Nouns:study, river, data
• Pronouns:you, we, their, its
• Verbs:run, is, become
• Adjectives and adverbs:clear, final, well
• Interrogatives:how, when, why

Words that stay lowercase in most title styles

• Articles:a, an, the
• Coordinating conjunctions:and, but, or, nor, for, so, yet
• Short prepositions:in, on, at, to, by, for, of, up

Two rules you can use on every title

1. Capitalize the first word and the last word, even if they are “small.”
2. Capitalize major words, then handle minor words based on the style you’re following.

What Is Capitalized in Titles? for essays, blogs, and emails

If you want a safe default, treat your title like a headline, not like a sentence. Major words get capitals, minor words usually do not, and the first and last word always do.

“Title case” is not one single rulebook, though. Different style manuals draw the line in different places, especially with prepositions. Pick the style your setting expects, then apply it the same way each time.

Title case vs. sentence case

Some settings do not use title case at all. Academic reference lists often use sentence case for article titles, where only the first word and proper nouns get capitals. Blog post titles and headlines often use title case. The win is knowing which one your task calls for.

Three common systems and where they diverge

• APA: Tends to capitalize words of four letters or more in titles, and it spells out title case and sentence case rules. The APA Style page on title case capitalization is a solid reference point.
• Chicago: Uses headline-style capitalization and keeps many prepositions lowercase, even when longer. Chicago’s Q&A on capitalization differences across styles breaks down the main differences.
• MLA: Often taught as “capitalize principal words,” with articles, prepositions, and conjunctions in lowercase unless they open the title or subtitle.

Tricky title parts that change the capitals

Most errors happen in the same handful of places. Learn these patterns and you’ll stop second-guessing every line.

Subtitles after a colon

When a title has a colon, treat the first word after the colon as a fresh start. Capitalize it even if it’s a minor word.

Hyphenated compounds

With hyphenated words, capitalize the first part. Many styles also capitalize the second part if it’s a major word. These patterns keep things clean:

• Capitalize both parts when both read like major words: Long-Term Plan, Well-Known Author.
• Keep a minor second part lowercase: Up-to-date Notes may become Up-to-Date Notes in some house styles that capitalize each element. Match your style.
• Keep prefixes attached to a word as one unit: Antiwar Speech, Nonprofit Funding.

“To” and the infinitive

In many headline styles, to stays lowercase because it acts like a short preposition, even in an infinitive.

Words after quotation marks or parentheses

Quotation marks and parentheses do not reset title case. Capitalize based on the word’s role, not on the punctuation around it.

Proper nouns, acronyms, and brand styling

Proper nouns stay capitalized: names, places, organizations, days, and languages. Acronyms stay in caps if that is how they appear in standard use. Brand names can keep their usual styling, even when it breaks a normal title rule: iPhone, YouTube, eBay.

Short words that act like major words

Short does not mean minor. “Up” can act like an adverb. In Wake Up Call, many editors capitalize it since it is part of a verb phrase.

How to choose the right capitalization style

Title capitalization is a matching job. You’re matching a teacher’s rubric, a publisher’s spec, or a site’s house style. Use this order to decide fast.

Step 1: Identify where the title appears

• Paper title: Often title case in MLA and Chicago; APA uses title case for the paper title.
• Source title in a reference list: Often sentence case in APA for article and book titles.
• Blog post title or headline: Usually title case.
• Email subject line: Either can work; teams often pick one.

Step 2: Pick the rule set and apply it every time

If you publish on a site, write a one-sentence house rule and keep it with your editorial checklist. If you write for class, follow the assigned manual even if you prefer another style.

Step 3: Run a fast scan before you hit publish

1. First word capped?
2. Last word capped?
3. Major words capped?
4. Articles and short prepositions in lowercase unless your style says otherwise?
5. Proper nouns and brand styling kept as they normally appear?

Mini rules for the words everyone argues about

Use these mini rules when you’re stuck on one word and you do not want to reread a style manual.

Articles

Lowercase a, an, and the, unless they start or end the title or subtitle.

Conjunctions

Lowercase and, but, or, nor, for, so, and yet in most title case styles. If one begins the title, capitalize it.

Prepositions

Short prepositions like in, on, at, to, by, for, and of are usually lowercase. Longer ones depend on the style system. Chicago and MLA often keep prepositions lowercase even when long; APA often capitalizes words of four letters or more.

Forms of “be”

They are verbs, so they are capitalized in title case: Why Grammar Is Hard.

Second words after a dash

After an em dash, treat the next word like a new start and capitalize it: Study Habits—What Sticks.

How to keep headings consistent across a full post

A post can have a title, H2s, captions, and table headers. Mixed capitalization looks sloppy. A few habits keep your page tidy.

Write a one-line house rule

Decide what you will do with minor words, then follow that rule on every new post. If multiple people publish on the site, add the rule to your editing checklist so everyone uses the same pattern.

Scan headings as a set

Before you publish, scroll through just the headings. If one line looks off, it often means a minor word was treated differently from the rest, or a brand name got “corrected” by a tool.

A checklist you can paste into your notes

• Capitalize the first word.
• Capitalize the last word.
• Capitalize nouns, pronouns, verbs, adjectives, and adverbs.
• Lowercase articles (a, an, the) unless first or last.
• Lowercase coordinating conjunctions (and, but, or, nor, for, so, yet) unless first or last.
• Lowercase short prepositions (in, on, at, to, by, for, of, up) unless first or last.
• After a colon or em dash, capitalize the next word.
• Keep proper nouns, acronyms, and brand styling as they normally appear.
• Apply the same rule set to every heading on the page.
