How a style guide works

A style guide is a short document that settles the arguments a team would otherwise have every week. It records the decisions that have no single right answer: whether you write “email” or “e-mail”, how you punctuate a bulleted list, whether headings take sentence case, how dates and phone numbers are formatted, which of your own service names take a capital letter. Someone decides once, writes it down, and everyone follows it.

Most guides sit on top of an existing public reference rather than starting from nothing. You pick a base — a dictionary for spelling, a recognised manual for punctuation — and then list only the places where your organisation differs, or where the base is silent. That keeps the document short enough that people actually read it, which is the whole point of having one.

Why a style guide matters

Inconsistency is quietly expensive. A reader who sees your business name spelled two ways on the same page, or a service called by three different labels across the site, gets a small signal that nobody is minding the details. That signal costs trust at exactly the moment a prospect is deciding whether you are worth an enquiry.

It also saves work. Without one, every draft gets edited on personal preference, the same arguments repeat, and freelancers guess. With one, a new writer produces something usable on the first attempt and the editor’s time goes on substance rather than commas. On a bilingual site — English alongside Nepali — a guide is what stops the two versions drifting into different terminology for the same service.

Common mistakes with style guides

The most common is length. A guide that tries to cover every possible case becomes a book nobody opens, and an unread rule is the same as no rule at all. The second is confusing style with brand voice: style is mechanics — spelling, punctuation, capitalisation, formatting — while voice is personality. They belong in the same folder but not in the same list, because they are checked in completely different ways.

The third is writing it once and never touching it again. Services get renamed, spellings settle, the site adds a glossary. A guide that contradicts the live site trains everyone to ignore it, and a rule that is ignored is worse than an absent one because it wastes the next writer’s time.

How to act on it

Build it from your own copy rather than from a template. Read through a handful of live pages, note every inconsistency you find, decide each one, and you will have a usable first draft in an afternoon. Add the terminology list next: your service names, the words you use for your customers, the phrases you deliberately avoid, and how you write anything numeric such as dates and prices.

Then put it where the writing happens — linked from the brief, not buried in a drive — and give one person the authority to settle new cases and record the decision. Review it whenever something changes on the site, and keep it to a length a new writer can absorb before their first task.

Do and do not

Do

  • Build it from inconsistencies in your own live pages
  • Keep a terminology list of your service names
  • Name one person who settles new cases

Do not

  • Copy a template that does not match your site
  • Mix mechanics and voice in the same list
  • Write it once and never revisit it

Questions people ask about this

What is the difference between a style guide and a brand voice guide?

A style guide covers mechanics: spelling, punctuation, capitalisation, number formatting, and how you write dates and service names. A voice guide covers personality: how formal you are, what you sound like, which words fit and which do not. Mechanics can be checked almost automatically. Voice needs a human read. Most teams keep both, and keep them separate.

Do I need a style guide if only one person writes?

A short one still helps. Your own choices drift over the months, and the moment you hire a freelancer, brief an agency or add a second writer, the document saves you re-explaining everything. Start with a single page of terminology and formatting decisions. It takes an afternoon, and it is far easier than reconciling years of inconsistent pages later.

How long should a style guide be?

Short enough that a new writer reads all of it before their first piece. Cover only the places where you differ from a standard reference, or where that reference has nothing to say, plus your own terminology. If it grows past a few pages, move the rarely needed detail into an appendix and keep the working rules at the front.
