Understanding capitalisation in titles is one of the most practical skills for anyone who writes for the web. While the rules might seem straightforward, the reality involves a blend of style guides, industry standards, and user expectations. This guide cuts through the noise to provide a definitive resource on how to capitalise correctly, ensuring your headlines look polished and professional.
The Core Principle: Nouns and Verbs
The foundation of title capitalisation lies in distinguishing between major and minor words. Major words, which typically include nouns, verbs, adjectives, and adverbs, should almost always be capitalised. These are the engine words that carry the core meaning of your headline. For example, in the title "How to Write Engaging Web Content," "Write," "Engaging," "Web," and "Content" are all capitalised because they are essential to the sentence's function. This rule holds true whether you are following AP style or another major convention.
Articles, Conjunctions, and Prepositions
Minor words, such as articles (a, an, the), coordinating conjunctions (and, but, or), and short prepositions (in, on, at), are generally left lowercased in the middle of a title. The idea is to keep the visual focus on the substantial nouns and verbs rather than the connecting tissue. However, there is a critical exception to this guideline: if a minor word is the first or last word of the title, it should be capitalised. A title like "A Guide to Running in the Park" correctly keeps "to" lowercased because it is a preposition, but it capitalises "A" because it is the first word.
The Devil is in the Details
Certain categories of words trip up writers more than others, particularly when dealing with prepositions of more than three letters. Words like "between," "through," and "without" are considered major words in title style because they are longer than three letters. Consequently, they should be capitalised even though they are technically prepositions. Another frequent point of confusion is the formatting of titles that include numbers. Numerals are generally preferred for readability in digital environments, but you must decide whether to spell them out based on your specific style guide. The word "to" in infinitives also presents a unique case; most style guides recommend keeping it lowercased, as in "How to Optimise Your Workflow," unless it is the first word.
