Creating reports in Power BI is more than just plugging in data and throwing in a few charts. Even the best-designed analytical logic can go unnoticed if the report is unreadable, cluttered, or visually inconsistent. A report’s aesthetics and readability directly impact how effectively users perceive and understand the presented data.
In this article, we present key principles for creating clear and aesthetic reports in Power BI – both from a design and technical perspective.
1. Visual consistency – the key to a professional look
Visual consistency is the foundation of report aesthetics. A consistent style enhances its professional appeal and facilitates data analysis. What is particularly noteworthy?
Page size
Use consistent page sizes throughout your report. This makes it easier to scale and publish on different devices.
Object style
Decide whether to use rounded corners or not – and stick to one version.
Fonts
Choose one font family and maintain a uniform style (size, weight, color) for the same elements – e.g. titles, chart axes, descriptions.
Text Readability
Fonts should be clearly visible – neither too small nor too large.
Spacing and Proportions
Elements should be evenly spaced and with consistent margins. Symmetry and proportions enhance aesthetics.
Colors
Maintain a consistent color palette consistent with your company’s visual identity (branding). Avoid excessive color and haphazard use. Also, remember that red is often associated with error or negative connotations – use it wisely.
Logo
Add your logo in SVG format (i.e. scalable), keeping it at an appropriate, discreet size – for example, next to the page title, adjusted to the text size.
2. Data readability – let the data speak for itself
A report shouldn’t require explanation. A well-crafted visualization guides the viewer through the data.
Selection of visualizations
Match the chart type to the type of data – e.g., a line chart for trends over time, a bar chart for comparisons between categories.
Rounding Values
Use consistent rounding and units. If you’re showing thousands in one place, don’t show hundredths in another.
KPIs and cards
Place key metrics in visible, easily accessible places. Let users see the most important data at a glance.
Highlights
It’s worth visually highlighting the most important information – using a different color or bold text.
3. Structure and Layout – A Report That Tells a Story
The structure of the report should guide the user through the data step by step, rather than overwhelming them.

-
Thematic page division
Groups of data and visualizations should be grouped according to themes.
-
From general to specific
Show aggregated data first, then detailed data – this facilitates interpretation.
-
Filtering
If a slicer (filter) applies to only one visualization, place it close to it. Don’t confuse it with global page filters.
-
Sidebars
If there are many filters, hide them in a sidebar to avoid cluttering the view.
-
Text minimalism
Avoid excessive descriptions. Let the data speak for itself, and the text only adds context.
-
Story telling
Visualizations should guide the user – show relationships, trends, results, and context.

4. Aesthetics = Credibility + Commitment
Why is all this so important? Because aesthetics influence:
-
-
-
First Impression
An aesthetically pleasing report inspires confidence. It looks professional and feels well-thought-out.
-
Recipient Engagement
Clarity encourages further data exploration.
-
Quicker Understanding of Information
The less clutter, the easier it is to absorb key information.

Summary
A visually appealing Power BI report isn’t just a matter of taste. It’s a communication tool – the more readable and aesthetically pleasing, the more effective. Consistency, readability, appropriate structure, and a skillful selection of visualizations make data understandable and useful.
Create reports that not only show numbers but also tell a story. After all, data should speak for itself.
