Bento Box Style in Power BI: A Modern Approach to Dashboard Design
1. The Origin of the Bento Box Style
The Bento Box style takes its name from the traditional Japanese lunch box, where various foods are separated into neat, individual compartments within a single container. In the digital world, this concept has evolved into a dominant UI/UX trend, popularized by tech giants like Apple and Microsoft.
Instead of a cluttered canvas of overlapping visuals, a Bento-style dashboard organizes information into distinct "cards" or "tiles." Each tile serves as a dedicated space for a specific metric or insight, creating a harmonious balance between variety and order. It’s not just a layout; it’s a philosophy of containment and clarity.
2. Why Choose Bento Box for Power BI?
Implementing a Bento layout in Power BI isn't just about following a trend - it solves several critical data visualization challenges:
Implicit Structure: By enclosing visuals in tiles, you provide immediate visual boundaries. Users can scan the report and instantly identify where one insight ends and another begins.
Reduced Cognitive Load: Large datasets can be overwhelming. Bento Box breaks complex information into "bite-sized" chunks, making the dashboard much easier to digest and interpret.
Adaptability: The grid-based nature of Bento designs makes it easier to plan layouts that work across different screen aspect ratios, ensuring your Power BI reports look professional on any monitor.
Visual Cleanliness: It eliminates the "floating visual" look, replacing it with a polished, app-like interface that builds trust with business stakeholders.
3. Core Principles
To pull off a professional Bento look, you must adhere to these four design pillars:
The Grid System: Everything must align. Whether you use a 12-column or 8-column grid, your tiles should have consistent spacing (gutters) between them. Precision is key - even a 2-pixel misalignment can break the premium feel.
Corner Radius (The "Squircle"): Modern UI is rarely sharp. Using rounded corners (typically between 8px to 16px) for your tiles creates a soft, modern, and approachable aesthetic.
Negative Space (Breathing Room): Don't crowd your tiles. Leave enough "white space" around the charts inside the boxes. This allows the data to "breathe" and prevents the report from feeling cramped.
Visual Hierarchy through Scaling: Not all boxes should be the same size. Use larger tiles for your "North Star" metrics (KPIs) and smaller tiles for supporting details. This naturally guides the user's eye to the most important information first.
4. Implementation in Power BI
Now, we will apply the core principles mentioned above to a Power BI report. This requires a few specific technical steps:
Important note: All parameters mentioned below are for reference only. You should experiment to find the settings that best fit your needs - this is how you truly transform knowledge into your own skill.
4.1. Canvas Background
-> Set the color to #F5F5F5.
4.2. The Grid System
Alignment is key. Maintain consistent spacing between visuals. Let’s use a spacing of 8px.
4.3. Corner Radius
Go to View > Themes > Customize current theme > Visuals > Border.
-> Set the color to #EEEEEE and the radius to 15px. This global setting saves time by applying the style to all visuals automatically.
4.4. Visual Padding
Due to the 15px corner radius, set the padding to 8px for the top and 12px for the left, while keeping the default settings for the right and bottom.
4.5. Color Palette
Choose an appropriate color palette that fits your specific project or company branding.
4.6. A Sample Result
The dashboard below demonstrates the Bento Box design. The core principles applied here include consistent spacing (8px) and a 15px corner radius with a subtle light gray border, which makes the visuals "pop" against the background.
