And this type of brand recognition can help your organization to stand out among your competitors.

What are the elements of a style guide?

A style guide contains guidance on grammar, punctuation, and text composition. But an effective style guide goes beyond communication basics and brand guidelines. It lays out how you speak to your audience across all your channels. Consistent and clear communications that showcase your brand are made up of many key elements. Here are some of the essentials.

Grammar rules

A style guide is the perfect place to highlight the basic rules of grammar. It’s also a good idea to list commonly misused words. Including their/they’re/there, effect/affect, and insure/ensure. Or misused or misheard phrases (eggcorns), such as “biting my time” (instead of biding).

Your style guide should also provide guidance on capitalization. Particularly those related to your organization’s brand and product names. Proposal software can instantly flag non-compliant and off-brand language.


Correct punctuation use, and indeed, incorrect punctuation use, can change the meaning of a message. The comma makes all the difference between “Let’s eat, Grandma,” and “Let’s eat Grandma.”

Make sure your proposals aren’t let down by poor punctuation. Your style guide should explain commonly misused elements including hyphens (em dash vs. en dash). Also include guidelines on the use of parentheses, period placement, and the infamous Oxford comma.

Acronyms and abbreviations

In your style guide, you should lay out your strategy for acronym and abbreviation use. Do you explain abbreviations in brackets immediately after the first use of the full term? Do you spell out the full name of a product, service, or organization in the first instance? Followed by the acronym in subsequent mentions? Or do you have a limit as to the number of acronyms or abbreviations in each paragraph? 


Complex sentences packed with long, difficult words can lead to people tuning out and missing key messages. Your style guide should give direction on message readability. How long should each sentence or paragraph be? How can you reduce complexity with plain language instead of jargon?

The Flesch reading ease score measures the readability of any text. It uses the average sentence length and number of syllables in each word. It assesses the text and offers a score between 1 and 100, with 100 being the highest readability score. This is a great way to minimize the complexity of your copy, ensuring you get your message across clearly.

Voice and tone

Your style guide should offer guidance on how you speak to your audience. Whether that’s your customers, suppliers or workforce. Is your tone helpful, friendly, educational or matter-of-fact? Do you avoid jargon altogether or explain particular references in plain language? Have you made it clear that writers should use only the active voice, never passive? Should you have the same tone across all platforms?

Five winning style guide examples

There are a number of style guides that have stood the test of time and are generally recognized as definitive in their specific field. The Associated Press (AP) style guide is arguably the go-to guide for news writing. But its influence on writing, in general, is far-reaching. MLA Style focuses on scholarly or academic writing. The Chicago Manual of Style is most commonly used for historical writing. The American Psychological Association (APA) style is generally used in the social sciences area.
