Title Case or Sentence Case? Titles & Headlines

Look at a book cover: Harry Potter and the Chamber of Secrets. Notice how most words have a capital, but a few little ones don't. That's title case, and there's a simple rule for it.

Why titles look different from sentences

In an ordinary sentence, only the first word and any names get a capital. Titles play by their own game. On a book or film title, most of the words go up, and only a few small joining words stay small. That is why a title looks so different from a normal line of writing, and why it can feel confusing the first time you try to write one. But there is a clear pattern behind it, called title case, and once you can see which words go up and which stay down, titles stop being a guessing game.

The title-case rule

In the title of a book, film, song or story:

• Capitalise the important words, the ones carrying the meaning: nouns, verbs, adjectives, adverbs. Chamber, Secrets, Lion, Wardrobe.
• Leave the little joining words lowercase, a, an, the, and, but, of, in, to, unless they are the first word.

The Lion, the Witch and the Wardrobe Harry Potter and the Chamber of Secrets

See how the, and, of stay small in the middle, but The is capital at the start, because the first word of a title is always capitalised.

Watch out, always capitalise the first and last word

Even a little word gets a capital if it is the first or last word of the title:

A Bug's Life (A is capital, it is first) The Day the Earth Stood Still

This rule beats all the others. If a title happened to end on a small word, that word would still take a capital, simply because it is last. First word up, last word up, whatever they happen to be.

Don't lowercase a word just because it is short

Here is a mistake people make in the other direction. They see a short word and make it lowercase to be safe, even when it is an important word. Short verbs and pronouns still take a capital, however tiny: What Is Life? keeps its Is; The Day the Earth Stood Still keeps Stood. Length is only a clue for the little joining words like of, the and and. A short but meaningful word like is, be, we or it still goes up.

The little joining words to keep small

It helps to know exactly which words stay lowercase in the middle of a title, so here is the short list to keep in your head:

• articles: a, an, the
• short joining words: and, but, or
• short prepositions: of, in, on, for, to, with, by

Every one of these stays small unless it is the first or last word of the title. Everything else, the nouns, the verbs, the adjectives, the describing words, goes up. So in The Rise of the Roman Empire, only of and the stay down; Rise, Roman and Empire all rise. A handy way to build a title is to write it all in lowercase first, then lift up only the words that carry real meaning, plus the first and last word whatever they are. That two-step method beats staring at the whole title and hoping.

The tricky edge: names inside titles

Titles often contain names, and those names keep their capitals no matter what. In Charlie and the Chocolate Factory, Charlie is a person's name, so it would be capital even in an ordinary sentence. In The Lord of the Rings, the little words of and the stay small, but the meaning-carrying words go up. And do not "correct" a famous title to match your own taste. If a book is called The Hobbit, that is how you write it in an essay, capital T, capital H, even if you would normally leave the small. You only invent the capitals yourself for a heading that is genuinely your own.

Sentence case: the quieter option

There is a second, simpler way to write a heading, and it is worth knowing so you are not surprised when you meet it. It is called sentence case, and it works exactly like an ordinary sentence: capitalise only the first word, plus any names, and leave everything else lowercase. So The rise of the Roman Empire is the same heading in sentence case that The Rise of the Roman Empire was in title case. Neither is more correct than the other; they are just two systems. Book and film titles almost always use title case, but a heading in your own project or an email subject line can happily use sentence case for a cleaner, more modern look. The one rule that matters is to pick one system for a piece of writing and stick with it, rather than swapping halfway through.

Why it matters

Titles turn up more than you might think: the book you are reviewing, the film you are writing about, the heading on your own project, the name of a poster. When you write a title in clean title case, it looks confident and finished, exactly the way a real book cover looks. When you either capitalise every single word, The Lord Of The Rings, or leave everything lowercase, it looks careless. Getting titles right is a small skill that makes essays and projects look properly put together, and it is the sort of detail a teacher notices at once.

Answers

1. Charlie and the Chocolate Factory
2. The Lord of the Rings
3. Diary of a Wimpy Kid
4. How to Train Your Dragon ("to" stays small; "Train" is a verb, so up)
5. A Series of Unfortunate Events ("A" is first, so capital; "of" stays small)
6. The Day the Earth Stood Still ("Stood" is a short verb but still goes up)
