Style sheets: What are they, and do I need one?

Updated: Jan 7

Style sheets are miniaturized versions of style guides, and yes, you need one. That doesn’t mean you need to make one yourself, though. Most professional editors that I know create style sheets for their clients, and I am no exception.

If you’re a first-time author, let’s cover the basics. You may be asking yourself, “What is a style guide?” In high school or college, you probably heard mention of MLA format. It's a style of writing geared more toward academics, not manuscripts. The Chicago Manual of Style (CMOS) is the style guide that editors refer to when they work through manuscripts. It is nearly impossible to memorize style guides cover to cover, so my physical copy of CMOS is within reach while I’m working away at my desk.

All-inclusive rules for punctuation can be found in The Chicago Manual of Style, including pages upon pages of comma usage. Ever wonder what a semicolon (;) is used for? It’s in there, too, along with rules on capitalization and when one should and should not spell out numbers. There’s also an entire section on manuscript preparation, editing, and proofreading.

The formatting of style sheets, on the other hand, varies from editor to editor. Before I began making style sheets for my clients, I searched the interwebs for templates. The style sheet I use is a compilation of a few I found online:

At the top of my style sheet's first page is Book Title, Series Title (if applicable), Author, etc.

The first section on my style sheet is Language & Style:
