Themes and layouts for Looker Studio reports

#01Brand kit for Data Studio

Apply theme colours in Theme and layout. Set default chart palette so new charts inherit it.

#02Page layouts that work in marketing

Cover page. Logo, report name, period, owner, distribution list, link to metric dictionary.

Ops page. Date control, scorecards, time series, channel table.

Deep dive page. Filters + one big table + one diagnostic chart.

Appendix. Definitions, join notes, connector register excerpt.

Keep vertical rhythm: 8 or 16 px spacing mentally. Align scorecards on a row. Do not scatter floating text boxes.

#03Accessibility

• Contrast matters on projectors.
• Do not encode meaning with colour alone; add labels.
• Avoid tiny 8 pt footnotes as the only place critical caveats live — use 10-12 pt footer.

#04Agency white-label checklist

1. Client logo on cover; your logo only if the contract allows.
2. Theme colours from the client brand guide, not your agency site.
3. Remove internal UTM debugging charts from the client view (use a separate ops report).
4. Confidentiality line in footer.
5. Filename and share title include client name + month.

See lesson 15 for parameters that swap client brand.

#05Worked example: Ledgerline

Ledgerline is a fictional accounts-payable software company. Details are illustrative.

Walkthrough

1. Design and ops spent one hour locking theme tokens.
2. Every new report was a copy of MASTER.
3. When Competitor D's deck looked louder, Ledgerline kept whitespace and won clarity in the QBR.
4. An intern once changed all scorecards to rainbow colours; MASTER + theme reset fixed it in minutes.
5. Agency partner reused the same spacing rules for client work.

#06Grid and spacing standards

#07Colour usage rules

1. Accent colour on the single most important KPI only.
2. Green/red only for deltas and status, never for category series if you can label instead.
3. Channel colours stay stable across reports (Paid blue, Organic grey, AI Assistant teal — pick and document).

#08Cover page copy block (template)

Report: {Name}
Audience: Leadership | Ops | Client
Period: {label}
Owner: {email}
Freshness: Ads/GSC 12h; GA4 {setting}
Dictionary: {link}
Confidential — {company}

Paste as a text box. Update parameters or manual fields at copy time.

#09Accessibility pass (15 minutes)

1. View the page on a laptop at 100% zoom — no overlapping boxes.
2. Check contrast of grey labels on grey backgrounds.
3. Ensure status is not colour-only (include On track / Off track text).
4. Read the footer at a glance from 1 metre (projector test).
5. Tab through controls if you expect keyboard users on the ops page.

Ship the accessibility pass before the colour debate.

#10Mobile and projector realities

Data Studio is desktop-first for most marketing teams. Still:

• Avoid tiny 8 pt footnotes as the only place caveats live.
• Test the exec page on a conference-room HDMI laptop at 1280-ish width.
• Do not rely on hover-only explanations for KPIs used in meetings.

If leadership mainly consumes scheduled PDFs, design for PDF: less interactivity dependence, more printed footnotes.

#11Brand kit Sheet (optional)

Agency MASTER references the kit; client copies overwrite hex values.

#12Chart junk to delete on sight

• 3D effects
• Unnecessary pie charts with 12 slices (use bar)
• Background images that reduce contrast
• Multiple competing trend lines on one axis without labels
• Decorative icons that force extra vertical scroll on mobile PDF

Whitespace is not wasted space. It is how executives find the KPI that matters.

#13Our view

Our view: branding is hierarchy, not decoration. One accent colour and a calm grid will outperform a loud template in every QBR that matters. Steal whitespace from chartjunk freely.

#14Dark mode temptation

Skip dark themes for shared marketing PDFs unless the brand demands it. Projectors and printouts punish light-on-dark more often than they reward it. Keep dark mode for internal ops experiments only.

#15Title casing

Pick sentence case or title case for chart titles and stick to it across the MASTER. Mixed casing reads as unfinished even when the data is perfect.

When in doubt, delete a chart before you add a colour.

#16Common mistakes

• Different fonts on every page.
• Five accent colours fighting for attention.
• No cover page, so Slack screenshots lack context.
• Editing MASTER directly.
• Decorative images that force extra scrolling without insight.

#17Try it yourself

Create a MASTER copy of your first dashboard. Set theme colours, add a cover page with owner and freshness, and rename the working copy for this week.

#18Quick quiz

1. Why copy a MASTER report?

Answer: To keep theme, layout and footers consistent without restyling from scratch.

2. Where should freshness be stated?

Answer: Cover page and footer on every page.

3. Should every scorecard use the accent colour?

Answer: No. Reserve accent for the primary KPI so hierarchy stays clear.

#19What should you check before the next lesson?

• Theme tokens documented.
• Cover page on the production report.
• MASTER file exists and is protected.

#20Common questions

Can I save a theme in Looker Studio? Yes. You can customise theme and layout settings for colours, fonts and chart styles, then reuse them when you copy a report or apply the same theme choices to new pages.

What size should a marketing dashboard canvas be? Pick one landscape size your stakeholders actually view (laptop or 16:9 for slides) and stick to it. Do not mix sizes inside one report without a reason.

How do agencies white-label reports? Use a cover page with the client logo, a shared colour theme, hide MentionX or agency chrome where contracted, and keep a footer with data freshness and confidentiality.
