I still remember the first time I was asked to create a style guide. It sounded simple — just a list of “how we write things,” right? But once I started, I realized it’s actually one of the most defining tasks for a technical writer. A style guide isn’t just about commas or hyphens. It’s about building consistency, credibility, and voice across everything you publish — from documentation to blogs to API references.
Let me walk you through how I built mine, what I learned the hard way, and how you can do the same.
So, what exactly is a style guide?
A style guide is your content’s rulebook — but not a rigid one. It tells your writers how to write, what tone to use, and what to avoid. Think of it as your project’s grammar, personality, and logic — all wrapped into one document.
When I first started creating mine, I looked at well-known examples like Google’s Developer Documentation Style Guide and Microsoft’s Writing Style Guide. But I quickly realized: copying them word-for-word doesn’t work. Every brand has its own voice and audience maturity level.
For instance, when I write for developers, I use contractions (“you’ll”, “don’t”), code examples, and direct second-person tone. But for research-based blogs, I switch to slightly more formal phrasing. The guide keeps both in check.
How to Create a Style Guide for your Documentation?
Let’s get practical now. Creating a style guide isn’t about copying rules from Google or Microsoft; it’s about translating your team’s writing DNA into something others can follow. When I built mine, I treated it like documenting a codebase — each rule had a reason, a test case, and a “why it matters” section.
In this part, I’ll break down the exact steps I followed — from defining tone and formatting to banning empty buzzwords — so that by the end, you’ll have a clear blueprint to build your own guide from scratch.
Step 1: Define your purpose and audience
Before writing a single rule, ask — who am I writing this guide for?
When I built mine, I wrote it for writers and contributors who were developers first, writers second. That changed everything. I didn’t need to explain what “JSON schema” means, but I did need to explain how to write an introduction that’s conversational yet authoritative.
Here’s what helped me frame it:
- Audience: Developers, technical writers, SEO specialists
- Goal: Make every piece technically accurate and human-readable
- Outcome: Anyone reading our docs should feel they’re written by one consistent voice
If you skip this step, your guide becomes just a grammar checklist — not a voice-defining document.
Step 2: Document your tone, not just your grammar
A big mistake I made early on was focusing too much on commas, quotes, and lists — and forgetting tone. Grammar matters, yes, but your tone decides how your readers feel.
In my guide, I added a section called Voice & Tone Matrix, inspired by Mailchimp’s model. It showed how tone changes across content types:
| Content Type | Tone | Example |
|---|---|---|
| API Docs | Precise & direct | “Send a POST request to…” |
| Blog Articles | Conversational & insightful | “Here’s what I learned when I tried…” |
| Release Notes | Crisp & neutral | “Added support for…” |
This chart helped everyone — from devs to editors — stay aligned.
So when someone new joined, they didn’t have to “guess” how we write. They had a clear reference.
Step 3: Set your writing standards — with real examples
Rules are useless if they’re abstract. You need examples that show before and after.
Here’s a small snippet from mine:
❌ Don’t:
The product provides a robust solution designed to enhance productivity.
✅ Do:
The product helps you automate repetitive workflows and cut setup time by 40%.
See the difference? One sounds like a press release; the other like something a developer can trust.
That’s the whole point — clarity, specificity, and proof.
Your guide should include similar pairs for:
- Tone (formal vs conversational)
- Sentence structure
- Banned words (like “robust,” “ever-evolving,” “bespoke”)
- Example rewrites
These examples do more than rules ever can — they teach thinking habits.
Step 4: Cover formatting and structure conventions
Formatting is where chaos starts if you don’t set rules early.
I still remember how confusing it was when one writer used inline code for API names, another used bold, and someone else just wrote them plain. The final doc looked inconsistent even though all were technically correct.
So, I made it simple:
- Code, commands, parameters: Use backticks —
like_this - UI labels or buttons: Use bold — Save Changes
- Headings: Always question form (“How to…”, “What is…”)
- Lists: Avoid nested lists beyond one level
- Tables: For comparisons or configuration options only
Once everyone followed this, editing became 10x faster.
Step 5: Include your banned phrases and preferred alternatives
This is one of my favorite parts of any style guide — the “banned list.”
Over time, I built a table of phrases that we all unconsciously used, especially from marketing habits.
| ❌ Avoid | ✅ Use Instead |
|---|---|
| Cutting-edge technology | Specify the version or capability |
| Robust solution | Fault-tolerant, high-throughput, or tested with X users |
| Seamless integration | Step-by-step integration process |
| Unlock the secrets | Explain the logic clearly |
| World of X | Just say “in X” |
It may sound small, but these phrases kill technical credibility. A good style guide protects you from that.
Step 6: Add examples of your brand’s “ideal paragraphs”
This one’s underrated. Every guide should have 2–3 model paragraphs that show how the final writing should sound.
Here’s one from my own guide:
“If you’ve ever written documentation for a fast-moving product, you know how easily things get outdated. That’s why we structure docs like living systems — modular, updatable, and easy to cross-link. The goal isn’t just to explain features, but to teach reasoning.”
That example says more than a rule ever could. It captures tone, rhythm, and sentence structure in one go.
Step 7: Keep it alive, not static
A style guide isn’t a one-time PDF. It should evolve.
When I started, I used a simple Google Doc. Then I moved it to a shared Markdown repo so contributors could suggest edits via PRs. Now, whenever I notice recurring edits during reviews, I update the guide.
It’s like a living organism — it grows with your writing culture.
Conclusion
Creating a style guide is one of those things that looks like “extra work” but saves massive time later. It keeps everyone — from writers to editors — speaking in one consistent, credible voice.
If you’re starting yours today, begin small:
- Define your tone
- Write a banned list
- Add real examples
Then refine over time. The goal isn’t to sound perfect — it’s to sound consistently human.
And once that happens, your content doesn’t just inform.
It feels like it’s written by someone who actually cares.
