Content in a Design System: Why Words Matter as Much as Components

A person doing handshake

When you think of a design system, what comes to mind? Buttons, cards, tokens, components? All good answers. But there’s another element just as important — and often overlooked: content.

Words shape the user experience as much as design. In fact, clear, inclusive content is what brings a design system to life.

This article explores why content is essential to every design system — especially in government — and how to build your own content standards into the system you use.

Why Content Deserves a Place in Your Design System

A design system is about creating a shared language. And language isn’t just visual — it’s verbal. Every label, heading, button, or error message is part of your product’s experience.

Without consistent content:

  • Buttons say different things across screens.
  • Forms confuse users with unclear instructions.
  • Alerts sound robotic in one place and overly casual in another.

With content standards in place:

  • You reduce cognitive load.
  • You write for accessibility and inclusion.
  • You build trust through consistency.

In government, clarity and plain English aren’t just good practice — they’re a requirement.

What Belongs in the “Content” Part of a Design System?

Think of your content layer as the verbal equivalent of your visual tokens and components. Here’s what to include.

1. Voice and Tone Guidelines

  • Voice is your brand personality — always consistent.
  • Tone changes with context — supportive in errors, concise in onboarding, direct in warnings.

👉 Example:
Your default voice may be clear, respectful, and informative.
In an error state, tone shifts to supportive:

“We couldn’t process your payment. Please try again or contact support.”

2. Style and Grammar Rules

Set your team’s approach to:

  • Capitalisation
  • Abbreviations
  • Oxford comma (yes or no?)
  • Contractions (use them — or don’t?)

Use a reference like the Australian Government Style Manual to align with national expectations.

3. Microcopy Standards

Microcopy includes:

  • Button labels
  • Form instructions
  • Empty states
  • Error messages
  • Confirmation messages

✅ Good example:

“Upload your file (PDF or Word, max 10MB)”

❌ Bad example:

“Please ensure document compliance before submission”

4. Inclusive and Accessible Language

Design systems must support inclusive, bias-free language. This includes:

  • Avoiding idioms and jargon
  • Using person-first or identity-first language as appropriate
  • Writing for reading level (e.g. Grade 7–9)
  • Gender-neutral pronouns

Example:
✅ “A person experiencing homelessness”
❌ “The homeless”

5. Content Tokens (Advanced)

Just like you have design tokens for spacing and colour, you can define content tokens for:

  • Standardised messages
  • Common labels and prompts
  • Status phrases (e.g. “Draft”, “In progress”, “Submitted”)

This helps keep text consistent across platforms and channels.

How Designers, Writers, and Developers Work Together

Creating a strong content system isn’t a writer-only task. It’s a team effort.

RoleContribution
Content Designer / WriterCreates voice and tone guide, writes microcopy, reviews labels and help text
UX / UI DesignerApplies tone to components, ensures space fits real content
DeveloperImplements copy in components, flags inconsistencies, adds content tokens
Product ManagerEnsures consistency across journeys and teams

Real Example: Button Label Variations

In some projects, you might find these four versions of the same action:

  • Submit
  • Send form
  • Save & continue
  • Confirm

A design system with content standards would define:

  • ✅ Preferred: Submit
  • ⛔ Avoid: Send form (too technical), Confirm (too vague)

Having this guidance improves consistency — and user confidence.

How to Document Content in Your Design System

Use the same structure as other components:

Component page: Button

  • Description
  • Visual examples
  • Code
  • ✅ Approved label: “Submit”
  • ⛔ Avoid: “Click here”, “Confirm”

Also create a Voice & Tone section in your documentation with examples for:

  • Errors
  • Success messages
  • Informational alerts
  • Onboarding and help

Tools and Resources for Content Standards

Here are a few helpful tools and references:

What Happens Without Content Standards?

Without clear guidance:

  • Content gets rewritten or improvised every time.
  • Designers leave placeholder lorem ipsum in production.
  • Error messages contradict your tone of voice.
  • Accessibility suffers.

Worse, users lose trust. Especially when content is confusing, incomplete, or inconsistent.

Final Tip: Write Your Design System in Plain English

The best way to advocate for clear content? Model it.
Write your design system documentation itself using:

  • Plain language
  • Short paragraphs
  • Helpful headings
  • Active voice

Make your content easy to use — just like your components.

Content is not a nice-to-have in your design system. It’s foundational.

Clear, inclusive, consistent content:

  • Helps everyone use the system well
  • Builds trust with the public
  • Improves accessibility and usability

Whether you’re a content designer, developer, or product manager — make sure your design system speaks clearly.
