Have you ever looked at the sky and noticed a cloud shaped like an animal or object? Your brain naturally interprets these patterns by filling in the gaps, a psychological process that helps us make sense of the world. This is at the core of Gestalt psychology, a fundamental concept in UI/UX design that influences how users perceive and interact with digital interfaces.

Understanding Gestalt principles allows designers to create intuitive, visually appealing interfaces that enhance usability, guide user behavior, and improve user experience (UX). In this article, we’ll explore Gestalt principles and their applications in UI design, backed by real-world examples and best practices.

What is Gestalt Psychology?

Gestalt psychology, developed in the 1920s by German psychologists, is based on the idea that “the whole is greater than the sum of its parts.” This theory explains how people perceive and organize visual information into meaningful patterns.

“The whole is other than the sum of the parts.” — Kurt Koffka

By applying Gestalt principles in UI/UX design, we can structure elements in a way that users naturally understand, reducing cognitive load and improving usability.

Key Gestalt Principles in UI Design

1. Proximity

A minimalistic design showing groups of geometric shapes arranged closely together to demonstrate the Gestalt principle of proximity, where nearby elements are perceived as related.

Elements that are placed close together are perceived as related. Grouping elements properly improves UI organization and readability.

Application in UI Design:

  • Grouping related navigation items together.
  • Structuring form fields logically.
  • Using whitespace effectively to separate content.

💡 Example: In Google’s Material Design, proper spacing ensures clear visual hierarchy and improved usability.

2. Common Region

A minimalistic illustration showcasing the Gestalt principle of common region, featuring geometric shapes grouped within clearly defined boundaries, such as enclosed areas with distinct backgrounds or borders. The design highlights how elements within the same region are perceived as belonging together, using a modern, clean aesthetic with a neutral color palette and subtle background gradient.

Objects enclosed in the same boundary (like a box or background) are perceived as grouped.

Application in UI Design:

  • Using cards for product listings (e.g., Amazon product cards).
  • Separating sections using background colors.
  • Defining buttons clearly with borders.

💡 Example: The card-based UI used in dashboards and product displays.

3. Similarity

A clean and modern illustration featuring geometric shapes of different colors and sizes, grouped by visual similarities, emphasizing how the mind associates similar elements.

Objects that share similar colors, shapes, or styles are perceived as related.

Application in UI Design:

  • Maintaining consistent button styles for CTAs.
  • Using uniform typography for headings and body text.
  • Highlighting active states with distinct colors.

💡 Example: Apple’s UI consistency across macOS and iOS interfaces.

4. Closure

An abstract design with incomplete geometric shapes such as a nearly complete circle and a dashed square, where the brain automatically fills in missing information to perceive a whole form.

The brain automatically fills in missing parts of an incomplete object, allowing for minimalist and efficient design.

Application in UI Design:

  • Simplifying icons (e.g., outline icons vs. solid icons).
  • Using partial elements to imply a shape or function.
  • Creating engaging logo designs (e.g., the FedEx logo’s hidden arrow).

💡 Example: Minimalist UI elements that reduce cognitive load.

5. Symmetry

A minimalistic illustration showcasing the Gestalt principle of symmetry, featuring geometric shapes arranged symmetrically along a central axis. The design highlights how symmetrical elements are perceived as a unified whole, using a modern, clean aesthetic with a neutral color palette and subtle background gradient.

Symmetrical elements create a sense of order and stability, making designs aesthetically pleasing and easy to navigate.

Application in UI Design:

  • Using grid layouts for portfolios and product listings.
  • Structuring dashboards with balanced elements.
  • Combining symmetry with asymmetry for dynamic layouts.

💡 Example: Instagram’s grid-based interface follows symmetry principles for clarity.

6. Continuation

A visually smooth illustration with flowing lines and curves that guide the viewer’s eye in a continuous direction, demonstrating how elements are perceived as an ongoing path.

Elements arranged in a line or smooth curve appear more related than those scattered randomly.

Application in UI Design:

  • Guiding users’ eyes through step-by-step processes.
  • Aligning elements in menus and progress bars.
  • Creating smooth reading paths with clear typography hierarchy.

💡 Example: Scrollable product carousels on e-commerce websites.

7. Common Fate

A dynamic illustration with geometric shapes and arrows moving in the same direction, illustrating how objects that share movement are perceived as belonging together.

Objects moving in the same direction or behaving similarly are perceived as related.

Application in UI Design:

  • Expandable menus (e.g., dropdowns, accordions).
  • Microinteractions (e.g., hover effects and animations).
  • Parallax scrolling effects.

💡 Example: Swipe gestures and animations in mobile apps.

How Gestalt Principles Improve UI Design

Applying Gestalt principles results in:

✅ Better user experience (UX) by reducing cognitive load.
✅ Improved readability through logical grouping.
✅ Stronger visual hierarchy to guide user focus.
✅ Higher conversion rates by making interfaces more intuitive.

Best Practices for Applying Gestalt Principles in UI Design

  • Use whitespace effectively to improve clarity.
  • Maintain consistency in UI components.
  • Follow design patterns from Material Design and Apple’s HIG.
  • Test UI usability with A/B testing and eye-tracking studies.

Conclusion

Gestalt principles play a crucial role in UI/UX design, helping designers create intuitive, aesthetically pleasing, and functional interfaces. By mastering these principles, you can improve usability, guide user behavior, and enhance the overall user experience.
