How to write a book or chapter title in title case
Book titles overwhelmingly follow Chicago headline style, which publishers and most bibliographies expect. Chapter titles follow the same rules. Paste a book or chapter title into the box above and the converter applies the right rule set instantly. You can switch styles to compare and pick the one that fits your context.
The quick rule
Use Chicago title case: capitalize the first and last words and all principal words, and lowercase articles, coordinating conjunctions and prepositions of any length. A strong, correctly cased title looks professional on a cover and in a catalog listing.
Example
Type a phrase like “the long road home through the mountains” above and watch each word fall into place: the major words are capitalized, the small connecting words are lowercased, and the first and last words are always capitalized.
Why correct casing matters here
Casing is the first thing a reader notices before they read a single full word. Inconsistent capitalization looks careless; clean title case signals that the rest of the work is just as carefully prepared. For a book or chapter title, it is a small detail that quietly builds trust.
