APA Sentence Case: The Ultimate Guide to APA 7th Edition

Formatting titles of articles, books, reports, and webpages for your written assignments can be an absolute nightmare. Style guides for academic papers are as rigid as they can get, and after a couple of reference list entries, you get lost in the titles, page numbers, publication dates, and surnames.

Let us help you! In this guide, we will dive into the following topics:

• What does sentence case mean in APA? Where do we use it?
• The rules of sentence case capitalization — in particular, for proper nouns and subtitles;
• Practical tips for formatting data, including a walkthrough of applying sentence case in Excel; and
• Why is APA sentence case the chosen standard for accessibility in modern publishing?

APA is a referencing style created by the American Psychological Association. Unlike other styles, it uses sentence case for titles in reference lists — that means it capitalizes only the first word of the title, aside from words that are capitalized by default. Styles like Chicago or Harvard, on the other hand, employ title case. The difference between sentence case and title case is that the latter enforces the capitalization of all the major words — those that carry meaning — only leaving prepositions, articles, and conjunctions in lowercase.

If you’ve ever looked at a reference list and wondered why it doesn’t match the bold, punchy titles on book covers, you’ve come across sentence case in APA. Put simply, this is a down-style approach in which you format a title just like a normal sentence, capitalizing the first letter and keeping the rest lowercase.

But what does sentence case mean in APA for the person actually writing the paper? It is all about creating a visual hierarchy. The APA uses this style to help you distinguish between a specific work (such as an article) and its container (the journal). While an article title stays “quiet” in sentence case, the name of the journal retains title case to get the spotlight. This isn’t just a quirk of the manual; it creates a visual map that lets your brain scan a long list of citations without hitting a mental wall. It’s designed to deliver information quickly without causing cognitive overload.

Even if a source title is printed in all-caps or title case on the original website, the APA expects you to convert it to sentence case.

Mastering sentence case capitalization is about understanding where the down-style stops and the exceptions begin. When in doubt, follow these six rules:

1. First word: The first word of the title is always capitalized in APA, regardless of whether it's an adjective, verb, preposition, or article.
2. Colon and em-dash: If your title contains a colon or em-dash followed by the continuation of the title, the first word after that character must be capitalized.
3. Proper nouns and adjectives: These include names of people, places, organizations, etc., as well as nationalities.
4. Numbered nouns: Whenever a noun is followed by a number — like “Chapter 3” — we capitalize the noun in question.
5. Acronyms: They stay as they are. As general grammar rules suggest, acronyms should always retain their form.
6. Other words capitalized by default: Like days of the week or months.

Referencing can be a bit tricky if all we have is a set of rules. Let’s look at some examples of sentence case, so that you can see it in practice:

• Book: Alice in wonderland
• Journal article: Translating the audiovisual: Between application and complexity
• Webpage: APA sentence case: The ultimate guide to APA 7th edition
• The headings of our articles are in sentence case as well, take a look! 😜

Notice that the letters after the colons are capitalized, as well as APA, since it’s an acronym. Everything else is lowercase.

If you’re managing a massive list of sources in a spreadsheet, doing the formatting manually is a major headache. Since Excel is built for crunching numbers, it lacks the “Change case” button you find in Microsoft Word, so we need to get creative.

Let’s say that you have the following text in cell A1: niCe TO mEeT YOu. How can we convert it to sentence case without retyping it manually?

We use the formula =UPPER(LEFT(A1,1)) & LOWER(MID(A1,2,LEN(A1)-1))

• UPPER(LEFT(A1,1)) forces the first character into uppercase; and
• LOWER(MID(A1,2,LEN(A1)-1)) forces all the other characters into lowercase

Here is what each of these elements would look like in Excel:

Let’s be honest: formatting references is nobody’s idea of fun. However, getting the hang of APA sentence case is the best way to keep your reference list clean and professional without losing your mind. By keeping those six capitalization rules in your back pocket — and using our Excel shortcut for the heavy lifting — you can speed up the process significantly. Now that you’ve got the basics down, you can stop stressing over the tiny details and focus on your actual writing.
