How Many Types of UX Laws Are There? A Complete Overview for Designers

Creating user experiences that feel seamless is both an art and a science. Behind every successful design are foundational principles, known as the laws of UX, which are critical for shaping how users interact with digital products. But how many types of UX laws are there, and why do they matter so much in modern design? This complete guide explores essential UX laws, cognitive principles, and actionable strategies to help you create experiences that users love.

Introduction to UX Design

At its core, UX design is about crafting products that meet user needs while minimizing friction. Good UX isn’t just about creating aesthetically pleasing designs; it’s grounded in a deep understanding of human behavior, including memory, attention, and decision-making processes.

When building interfaces, designers must account for working memory limitations, cognitive load, and mental effort. Even beautiful designs can fail when overlooked because they don’t align with users’ thinking and behaviour. Applying UX laws ensures that digital experiences are attractive and functionally intuitive, resulting in higher user satisfaction and retention.

What Are UX Laws?

UX laws are design principles based on psychology and behavioral science that explain and predict user behavior. These laws guide designers in creating layouts, workflows, and interactions that align with natural human tendencies.

Instead of reinventing strategies with every project, understanding UX design laws allows designers to optimize the user journey for maximum engagement. Whether reducing cognitive friction or improving navigation design, these laws make experiences more predictable and pleasurable.

For instance, applying the principles of cognitive load theory helps minimize the number of steps a user must take to complete complex tasks, leading to improved efficiency and satisfaction. The laws of UX simplify decision-making for designers, ensuring that every interaction is purposeful and user-centric.

Understanding the Different Types of UX Laws

Hick’s Law

Hick’s Law states that the more choices users have, the longer it takes them to make a decision. This is why minimalist menus or simplified checkout processes are so effective.

By limiting options and grouping them into categories, designers can speed up decision-making and reduce frustration. For example, Apple famously applies this principle in its product pages by offering only a few key product comparisons, helping users make faster decisions without overwhelm.

Miller’s Laws of UX

According to Miller’s Law, average people can retain 7±2 items in their working memory. Overwhelming users with more information increases the likelihood of abandonment.

Chunking information, such as breaking content into steps or categories, aligns with how users process information naturally. This approach significantly reduces cognitive effort, making user interfaces more approachable and efficient. Slack’s onboarding is a strong example—users are guided step by step with digestible bits of information to prevent overload.

Aesthetic-Usability Effect

The Aesthetic-Usability Effect emphasizes that aesthetically pleasing designs are perceived as more usable, even lacking functionality.

Users tend to forgive minor usability issues when designs are clean, harmonious, and visually delightful. To master this balance, explore how visual hierarchy impacts usability and why it’s crucial in UX. Creating aesthetically pleasing designs reduces mental effort and encourages users to interact positively.

Fitts’s Law

Fitts’s Law states that the time it takes to interact with a target is a function of distance and size. Large, well-placed buttons make digital interfaces more accessible and efficient. In e-commerce sites, for instance, placing “Add to Cart” buttons directly next to product images reduces the effort required for a user to take action.

Amazon has consistently optimized product page layouts by placing important actions within immediate reach, resulting in higher conversion rates. Fitts’s Law reinforces the importance of optimizing digital interfaces for efficiency and accessibility.

Jakob’s Law

Jakob’s Law suggests that users spend most of their time on other sites, influencing their expectations. Consistency with established norms reduces the learning curve and ensures that users prefer your site because it “just works.” When updating interfaces, maintain consistent UI patterns to align with users’ expectations based on their experiences elsewhere.

LinkedIn maintains expected user behaviors in its interface, mirroring standard social media interactions while offering unique professional tools.

Law of Proximity

The Law of Proximity tells us to group related elements based on spatial closeness. Proper grouping of associated elements improves scannability and ensures smoother navigation through the interface. This principle is crucial when designing forms, menus, or multi-step processes. It encourages efficient user navigation and seamless information processing.

Law of Similarity

Users perceive similar elements as part of the same group. Maintaining consistent design elements like colors, fonts, and shapes strengthens brand identity and usability. Designers should leverage visual cues to emphasize the relationship between multiple similar objects, reinforcing usability and trust.

Spotify applies this law by keeping album art, play buttons, and playlists consistent, ensuring users can quickly interpret repeated elements.

Law of Uniform Connectedness

When visual elements are physically linked or grouped within a clearly defined boundary, users naturally perceive them as related.

Highlighting steps within a multi-stage checkout process effectively applies this principle. This approach aids users in understanding the structure and flow of information. Our WordPress maintenance services illustrate this with logically connected service tiers and icons for fast comprehension.

Law of Common Region

Elements within the same closed boundary tend to be perceived as grouped. Designers can use borders, shading, or background colors to visually separate different sections. Clear separation helps users focus on the active user area without confusion.

Law of Closure

The Law of Closure states that users tend to perceive a complete shape even if parts are missing. Designers can use incomplete visuals creatively to suggest form and encourage mental engagement.

WWF’s panda logo is a great real-world application; it’s visually incomplete but instantly recognizable, leveraging closure to imprint brand memory.

How Cognitive Factors Shape UX

Working Memory and Cognitive Load

Understanding the limits of working memory is critical in UX design. Users can only process a few pieces of information at a time. Heavy cognitive load forces users to expend greater mental effort, often leading to frustration or abandonment.

Designers should prioritize clarity, simplicity, and progressive disclosure, only revealing necessary information when users need it. A detailed example is our piece on WordPress SEO Optimization, where content is structured with collapsible tips to avoid overwhelming the reader.

Serial Position Effect

The Serial Position Effect states that users are likelier to remember the first and last items they encounter. When designing your CTAs or content layout, ensure that the most important messages appear in these memory-strong positions. Using this principle can drive higher conversion rates and better user satisfaction.

Zeigarnik Effect

The Zeigarnik Effect states that users remember uncompleted or interrupted tasks better than completed ones. Progress bars, visual indicators, or save-and-resume features can leverage this principle, especially during long forms or complex tasks.

Google Docs autosave and revision features use this bias by signaling tasks aren’t “done” yet, prompting users to revisit and complete documents.

Cognitive Load Theory

Cognitive load theory suggests that users abandon tasks requiring excessive mental effort.

Simplifying interfaces, avoiding unnecessary complexity, and providing intuitive navigation reduce cognitive overload and create better experiences. Reducing complexity directly supports users in completing tasks efficiently and effectively.

Anchoring Bias

Anchoring bias influences how users interpret information based on the first piece of data they see. Presenting premium features first can set positive expectations for other product tiers. Understanding anchoring bias can improve pricing page designs and user onboarding.

Availability Heuristic

The Availability Heuristic refers to users relying on immediate examples that come to mind. Prominently highlighting positive user experiences can help users perceive your service as trustworthy and reliable.

This is the psychology behind strong testimonial placement on landing pages like Dropbox, which showcases logos and quotes from prominent brands to anchor trust quickly.

Human-Computer Interaction and Behavioral UX Laws

Jakob’s Law Revisited

As users spend most of their time on other sites, designers must ensure they mirror standard practices. Deviating too much from established patterns forces users to relearn behaviors, causing friction and dissatisfaction. Consistency reduces the learning curve and ensures familiarity.

Fitts’s Law Revisited

Optimizing button size and positioning is not just good practice; it’s essential for improving task efficiency. Designers must always consider how physical actions translate into digital behavior. Designing for efficiency reduces user frustration and enhances usability.

UX Principles for Visual Clarity

Reducing Ambiguous or Complex Images

The Law of Prägnanz suggests that users simplify ambiguous or complex images to create meaning. Minimizing visual clutter and presenting clear, organized content helps users focus on key elements without unnecessary confusion. Simplicity in visual elements promotes faster comprehension and more pleasant experiences.

Visual Cues and Progress Indicators

Clear visual cues such as arrows, contrasting buttons, and progress bars guide users toward desired actions. Guided interactions reduce mental effort, speed up task completion, and enhance the overall experience. Progress indicators capitalize on the psychological need for closure, motivating users to complete tasks.

Consistent Design Elements

Maintaining consistency across design elements reduces the cognitive load and boosts user confidence. Whether it’s colors, typography, or button styles, consistency signals trustworthiness and professionalism. Consistency allows users to predict interactions, streamlining navigation.

Cognitive Biases in UX Design

Von Restorff Effect

The Von Restorff Effect states that standout items are remembered better. Designers can emphasize necessary actions like “Sign Up” or “Buy Now” buttons by making them visually distinct. This principle should guide calls to action and promotional content.

Peak-End Rule

According to the Peak-End Rule, users judge an experience by its most intense point and end. Delightful “thank you” pages or smooth post-purchase processes can dramatically improve user satisfaction and loyalty. Designing with the Peak-End Rule in mind ensures that users leave with positive memories.

Practical Tips to Apply UX Laws

• Use fewer design elements for cleaner interfaces.
• Chunk information to fit within working memory limits.
• Apply a clear visual hierarchy.
• Emphasize CTAs using the Von Restorff Effect.
• Use progress indicators to reduce perceived complexity.
• Highlight key design elements using visual cues.
• Group related elements using the Law of Proximity.
• Design visually appealing experiences that align with user expectations.

Applying these techniques results in a user experience that feels effortless and enjoyable.

So, How Many Types of UX Laws Are There?

Although there is no absolute number, most experts categorize 20–30 major UX laws. These laws fall into:

• Cognitive Psychology Laws (e.g., Miller’s Law, Hick’s Law)
• Perceptual and Behavioral Laws (e.g., Law of Similarity, Peak-End Rule)
• Interaction and Navigation Laws (e.g., Fitts’s Law, Jakob’s Law)

Rather than memorizing all UX laws, successful designers focus on applying the right law based on the context of their digital interfaces. Using context-specific laws is essential for creating experiences that users understand intuitively.

Conclusion: The True Power of UX Laws

Understanding the laws of UX transforms the way UX designers approach problem-solving. Rather than guessing, designers can rely on proven psychological principles to motivate users, increase user satisfaction, and drive better business outcomes. Crafting designs based on human-centered laws helps ensure that users interact with products effortlessly, meeting their needs with the least cognitive effort.

Combining critical thinking, user research, usability testing, and continuous iteration ultimately sets exceptional designs apart. The future of UX design lies in mastering human behavior, minimizing cognitive load, and creating experiences that users love and remember.
