A brand voice chart is a one-page working summary of three or four voice principles. For each principle, include its audience purpose, observable writing behaviours, a clear boundary, and a short example. Keep tone-by-context and detailed editorial rules in linked resources. The chart should help someone make a decision while drafting, not merely describe the brand’s personality.
Choose principles with practical tension
Single adjectives—bold, friendly, expert—invite personal interpretation. A useful principle often balances two needs:
- expert without being academic;
- direct without being abrupt;
- warm without forced familiarity;
- optimistic without overstating certainty.
Base the principles on audience needs and the brand’s actual way of working. If customers face complex decisions, clarity and evidence may matter more than sounding playful. Review existing copy, customer questions and the brand voice guidelines before naming the principles.
Use five columns
A practical chart can contain:
| Principle | Why it matters | Do | Do not | Example |
|---|---|---|---|---|
| Clear direction | Readers need to know what to do next | Lead with the decision; use concrete verbs | Bury the action; use vague abstractions | “Compare the two plans” rather than “Explore your possibilities” |
Keep entries observable. “Sound confident” is difficult to review. “State the recommendation and its basis; qualify uncertainty” can guide a writer and an editor.
Add a link from each principle to more brand voice examples, vocabulary decisions and tone guidance. The chart should be a doorway, not the whole system.
Illustrative example: a research platform
Illustrative example: imagine a platform that helps small teams organise customer research.
| Principle | Why it matters | Do | Do not | Example |
|---|---|---|---|---|
| Useful specificity | Teams need to act on findings | Name the evidence and next decision | Call every observation an insight | “Three of six participants could not find pricing” |
| Calm curiosity | Research includes uncertainty | Ask open questions; state limits | Defend an assumption or force certainty | “This pattern needs testing with procurement leads” |
| Plain expertise | Methods should be understandable | Explain terms on first use | Use terminology to signal status | “A moderated session is led by a researcher” |
The examples teach decisions. They do not prescribe one sentence for every page.
Keep voice separate from house style
The chart need not contain every punctuation and capitalisation rule. Store recurring editorial conventions in a searchable style guide or brand vocabulary guide.
Voice principles govern character and judgement. House style resolves consistency details. Some rules overlap—plain language supports both—but separating them keeps the chart usable.
Microsoft’s public writing guidance describes its brand voice through principles such as warm and relaxed, crisp and clear, and ready to lend a hand. The useful lesson is the translation into writing behaviours, not the adjectives themselves.
Test and distribute the chart
Give the chart to people in marketing, product, support and sales. Ask each to revise a realistic piece of copy and note what remains uncertain. If a principle creates opposite interpretations, sharpen the behaviours or example.
Place the chart where writing happens: the content system, design system, support library and briefing template. An attractive slide hidden in a brand deck will not change everyday work.
Limitations and trade-offs
Compression makes a chart usable but removes nuance. Link to detailed guidance for high-risk or complex contexts. Do not expect the chart to replace positioning, messaging or legal review.
Too many principles reduce recall; too few may flatten meaningful character. Three or four is a useful starting constraint, not a universal rule.
Voice-chart checklist
- Limit the chart to memorable principles.
- Explain the audience value of each.
- Use observable “do” behaviours.
- Define a boundary with “do not”.
- Add realistic, original examples.
- Link to tone and terminology guidance.
- Test with different writing teams.
- Keep it beside working tools.
Frequently asked questions
Is a voice chart the same as a tone matrix?
No. A voice chart summarises stable principles; a tone matrix explains how expression changes across situations. Link the two.
Can we use more than four voice principles?
You can, but prioritise recall and distinctiveness. Combine principles that produce the same writing behaviour.
Who owns the brand voice chart?
A content or brand owner should maintain it, with input from teams that write and subject-matter owners responsible for accuracy.
Your useful next step
Draft one row for the principle your team uses most often. Replace every personality adjective with a visible writing behaviour, then ask two colleagues to revise the same sentence using only that row.
