Now that we’ve reached October, Halloween decorations have been slowly popping up in my neighborhood. Each time I go for a walk I see new cobwebs, gravestones, pumpkins…and lots of skeletons. Skeletons that are five inches to twelve feet tall, that have two heads, or light up, or are dressed up for the colder weather. Some are just a head and bony hands reaching out from the grass or supported by a tall shrub, reminding me of Hamlet holding a skull in the iconic scene from Shakespeare.

When I get back from my walk around the block, I sit down to edit the subheadings of a science article and I find myself recalling another moment from Hamlet—that phrase, to be or not to be—as I review which words to capitalize.
It’s those little words that get me. To, it, as, but, for. When you’re writing a title, heading, or subheading, there’s no one right answer for capitalizing these little words. For instance, I’ve titled this post in Chicago style: conjunctions like “or” stay lowercase and so do articles (i.e., a, an, the). The preposition “to,” meanwhile, is capitalized when it’s the first word but not when it’s in the middle of the title. Now if I were to write the title in AP style, which is typically used for newspapers and magazines, the “to” gets capitalized both times, because AP style also capitalizes the word when it is used as an infinitive (the infinitive here being “to be”).
So the answer to which words get capitalized in a heading depends on the context of how the word is being used and the style of the document—a newspaper headline won’t follow the same guidelines as the subheading of a nonfiction trade book, for instance.
When in doubt, or if you’re curious to compare all the style guides, you can check out https://capitalizemytitle.com/. This free tool lets you type in any headline and toggle among Chicago, AP, MLA, APA, and other styles to see what words to capitalize. Like any digital tool, it might not always pick up on things that a human would, such as whether a word is being used as an adverb (the other instance of capitalizing “to”), but it is a great start to proper formatting and a quick way to double-check your thinking as you review the capitalization in titles and headings.
Whether you’re dusting off the cobwebs of an old piece of writing or drafting fresh content from a bare-bones outline, consistent capitalization is a small way to add a little extra boost.
