As a growing UX expert or UI enthusiast, mastering Gestalt principles is essential for delving into the depths of user-focused design. These principles are pivotal in comprehending human perception of forms and utilizing this knowledge to enhance the intuitiveness and appeal of your designs.

This piece delves into one of the fundamental Gestalt principles - the Law of Prägnanz. We'll explore its definition and, crucially, its significance for designers. Dive in with us!

Defining the Law of Prägnanz

The Law of Pragnanz, also known as the law of simplicity, is a principle in psychology suggesting that when faced with complex shapes or ambiguous arrangements, our brains prefer to interpret them in the simplest way possible. It was first proposed by German psychologist Max Wertheimer in the early 20th century.

This concept is often described as the law of 'good figure.' Consider the Olympic logo: what do you see? Most people identify it as a series of five interlocking circles. This interpretation is favored because seeing it as a network of interconnected lines is more cognitively demanding.

Even if you find it simple to view it as connected lines, the principle holds: perceiving objects in their most basic form enables quicker recall and uses fewer cognitive resources.

Gestalt Psychology: Unveiling the Unified Perception of the Human Mind

Gestalt psychology, a pioneering school of thought, proposes that human perception and behavior are best understood as interconnected rather than isolated elements. This approach asserts that we perceive our environment as an integrated unit, enabling us to comprehend the world holistically.

Developed in the early 20th century in Austria and Germany, Gestalt psychology has significantly influenced contemporary insights into human sensation and perception. It challenges the traditional notion of processing individual components of sensory input separately.

The movement gained momentum in 1910 with Austro-Hungarian psychologist Max Wertheimer's exploration into optical illusions, particularly the 'Phi phenomenon.' This discovery illustrated how our minds perceive motion and became a cornerstone of Gestalt psychology. This branch specifically delves into how our minds organize and interpret visual stimuli, shaping our understanding of visual perception and its role in cognitive processes.

Building on the foundation of Gestalt psychology, it's essential to delve into the specific principles that govern our visual perception. These principles, central to understanding human visual cognition, provide insights into how we group and interpret visual stimuli daily. By examining these fundamental Gestalt principles, we can appreciate how our brain organizes what we see, influencing everything from design to our interpretation of everyday objects. 

This understanding is not just theoretical; it has practical applications in various fields, including design, art, and visual communication, enhancing the effectiveness of visual presentations and interfaces. Let's explore these main Gestalt principles to grasp their impact on our visual experiences better.

  • Proximity: This principle states that objects or shapes close to one another appear to form groups. Even if the shapes, sizes, and things are radically different, if they are close, we see them as a group. Incorporating proximity in design leads to a 25% improvement in information organization and retention, according to recent research.
  • Similarity: According to this principle, similar items tend to be grouped. It's not just physical proximity; similarity in color, shape, size, or other attributes can group separate elements into a single unit in our perception.
  • Closure: Our minds tend to fill in missing information to create a complete, whole object. This principle is why we often perceive a complete image even when parts of it are missing.
  • Figure/Ground: This principle describes how our eyes differentiate between an object (the figure) and its surrounding area (the ground). It's crucial in determining what we focus on in a visual composition.
  • Continuity: This principle suggests that our eyes prefer to see continuous movement or flow in a pattern rather than disrupted or separate parts. We perceive elements arranged on a line or curve as more related than elements not on the line or curve.
  • Symmetry and Order: We tend to perceive symmetrical objects as belonging together regardless of their proximity. This principle is often associated with harmony and balance in visual composition.
  • Common Fate: Elements moving in the same direction are often perceived as a unit. This principle is more dynamic, dealing with motion and predicting future position based on movement.

Understanding these principles helps designers, artists, and psychologists grasp how visual information is organized by the human mind, leading to more compelling visual communications.

Utilizing the Law of Prägnanz in UX Design

After delving into the theory of Prägnanz, let's explore its practical application in design.

Embrace Simplicity in Shapes

Echoing a key Gestalt principle, simpler shapes are more accessible for users to process and remember. For instance, a square is generally more recognizable and memorable than a complex, abstract shape. This concept is pivotal in UX design, where straightforward, memorable forms are favored for user ease and recall.

Embrace Minimalism in Design

Our brains are naturally inclined to avoid information overload, a tendency supported by research showing that users often leave websites within 10-20 seconds if they don't find the content compelling enough. We aim to create inherently simple interfaces by applying this understanding to design, offering an intuitive and gratifying user experience.

This approach is not just about aesthetics; statistics indicate that websites with a well-organized layout and minimal web design can increase user engagement by up to 200%. A notable example of effective simplicity in design is Wikipedia’s language-switch feature in its search bar. This minimal yet highly functional element greatly enhances user efficiency and satisfaction, demonstrating how streamlined design can significantly improve the usability of a platform. Therefore, we cater to the user's cognitive preferences by embracing simplicity and intuitiveness in design, resulting in more engaging and user-friendly interfaces.

Apply Prägnanz in Wireframing

In wireframing, the Prägnanz law is invaluable. It guides us to design elements our eyes can easily group, forming a coherent whole. The goal is to craft designs that are immediately clear and understandable, reducing the cognitive load for users. This approach is crucial from the early design stages, such as low-fi wireframes. Prägnanz guides us to focus on vital design elements - straightforward navigation, calls to action, and page titles. Moreover, it influences the information architecture, ensuring it is intuitive and easily navigable for users.

Enhancing Visual Hierarchy with Prägnanz

The Law of Prägnanz plays a significant role in establishing a clear visual hierarchy in UX design. By prioritizing elements based on simplicity and recognizability, designers can guide users' attention to critical information and actions. This involves organizing interface elements to align with the user's natural perception, making the most important features stand out effortlessly. For example, using bold and large fonts for headlines and contrasting colors for call-to-action buttons helps create an instantly understandable hierarchy.

Streamlining Customer Journeys

Incorporating the Law of Prägnanz in mapping customer journeys ensures a seamless and intuitive navigation experience. You can read how to map a customer journey in our previous article. Designers can minimize confusion and cognitive load by simplifying users' paths to complete tasks. This approach involves reducing the number of steps in a process, clarifying button labels, and using familiar icons and layouts. The aim is to create a natural and effortless flow where users can move through the application or website design without hesitation or doubt, enhancing overall user satisfaction and engagement.

These steps highlight the practical applications of the Law of Prägnanz in UX design, focusing on enhancing visual hierarchy and streamlining user journeys to create more efficient, user-friendly digital products.


The Law of Prägnanz, often called the Law of Simplicity or the Good Figure, is a pivotal principle in understanding how individuals interpret visual elements. It posits that the human mind prefers the most straightforward interpretation of visual stimuli, steering clear of complex patterns that demand more cognitive effort. This insight into human perception is crucial for crafting more engaging and intuitive visuals in products and services.
