What are the laws of UX? Top 10 laws explained

Discover the essential UX laws that every designer should know to create intuitive and engaging user experiences. This article explores key principles like Jakob’s Law, Hick’s Law, and the Peak-End Rule, offering insights on how to apply these laws in your design projects to enhance usability and user satisfaction.
UX Laws

With human life totally plunged into the digital world, and each user having his arsenal of apps, websites, and all kinds of different digital tools, a couple of things have grown quite crucial. Namely, the creation of comfortable, engaging experiences. For designers, UX laws are a set of psychological principles and behavioral insights by which designers may build such an experience. These are anything but theoretical abstractions; they are practical frameworks through which even the most complex designs may be rendered into intuitive and enjoyable interactions.

This article investigates a few of the empowering UX laws of modern design. Designers can make decision-making easier by applying insights from these principles to develop intuitive navigation patterns and layout-optimized layouts. From simplifying choice to increasing engagement, each law empowers the designer to fulfill, at times exceed, the expectations of users while making the interactions natural, accessible, and rewarding.

It makes the design process so much richer for both novice and experienced UX designers because it enables them to create experiences that will go beyond meeting the needs of users; rather, it’s the experience itself that strikes a chord with the users. Let’s dive into some key UX laws that make up the foundation of the guiding rules in effective user-centered design.

What is a UX Law?

UX laws are the established principles and guidelines from psychology that inform designers about how users create interactions with digital interfaces.

What is a UX Law

Human behavior and cognitive science should make designers understand and anticipate what users will do in order to make their user experiences more intuitive, efficient, and enjoyable.

Designers apply these practical UX laws when considering in what ways people reliably process information to better facilitate seamless interactions and reduce user friction, equipping them with the tools they need for successful design.

 

Key UX Laws

Here, we’ll outline the necessary UX laws by explaining what each principle means and then how that is applied in a real situation, and, finally, how it’s going to affect users.

Guidelines help designers frame interactions and ensure their products feel intuitive for users.

1. Jakob’s Law

  • Definition: Most of the user’s time is spent elsewhere. Thus, users will assume that your site will work like all of the other sites they currently know.

Jakob’s Law is all about familiarity. Users expect websites (and other digital products) to be designed in a way that’s consistent with others they’ve used in the past.

  • Application: Employ design patterns more relatable to the user in order to meet expectations. It, for example makes use of a standard layout for navigation; placing a menu bar at the top reduces the learning curve for users.
    Impact: By following common design patterns, you will be making the users comfortable and confident while using your site, meaning greater usability and satisfaction of your users.

2. Hick’s Law

  • Definition: The greater the number of choices or difficulty increases, the greater the time it takes to make a choice.
  • Application: Reduce choices so users can decide more quickly. For example, when designing menus, just include a few choices or make use of groupings and categories so as not to have too many options.
  • Impact: The less the choice overload, the more efficiently users operate in terms of a smoother experience and less friction in attaining their goals.

3. Miller’s Law

  • Definition: A person is only capable of holding about seven items in one’s working memory.

Miller’s Law states that the average person can only hold 7 items in their working memory, plus or minus 2.

  • Application: Chunking or breaking information into groups or manageable pieces to understand better. Helping to break information down using a variety of techniques such as headings, bullets, or a visual hierarchy of information to make the information easier to digest.
  • Impact: By chunking information into manageable pieces, the user can process the information or content in very digestible pieces – not feeling overwhelmed – and allowing the user to read and retain better.

4. Fitts’ Law

  • Definition: The time it takes to reach a target depends on both the distance to and size of the target.
  • Application: Place frequently-used buttons in easy reach and make them larger, especially on mobile where users will be engaging with their thumbs.
  • Impact: By making the areas that are tappable larger the user can grasp those areas more easily reducing frustration and creating a much-satisfying efficient experience for the user of your application.

5. Postel’s Law

  • Definition: Be liberal in what you accept, and be conservative in what you send.
  • Application: Allow the users to enter information in multiple formats. For instance, if you are prompting for a date, the user may define that date in several ways. Your output should be in a standardized and unambiguous fashion. The lesson here is that when allowing flexibility in the format of the input you will have designed a forgiving interface-one that can absorb user mistakes and decrease frustration.

6. Peak-End Rule

  • Definition: Users judge their experience largely by its peak (best or worst moment) and its end.
  • Application: Make the experience at critical touchpoints as positive as possible. Examples include onboarding and checkout confirmation.
  • Impact: By improving an interaction’s peak and ending, you will create a long-lasting, positive impression that can make a huge difference in user perception and satisfaction.

7. Aesthetic-Usability Effect

  • Definition: Users often see beautiful designs as more usable.
  • Application: Invest in polished and visually appealing design elements while maintaining the functional quality of your product.
  • Impact: A good and well-designed interface builds trust and can even let small usability errors slide while creating a positive feeling within the application.

8. Doherty Threshold

  • Definition: When the users’ interaction with the system is free from noticeable delays, productivity increases.
  • Application: Keep load times as short as possible. Apply feedback, like loading animations, to keep users occupied when there are longer wait times.
  • Impact: Minimizing delays and keeping users informed keeps the flow smooth; users feel more in control, which increases productivity.

9. Tesler’s Law

  • Definition: Any application has a degree of inherent complexity that no redesign can reduce.
  • Application: Eliminate non-core features to maintain neat and simple design.
  • Impact: It simplifies the interface so your users pay Attention to the core activities in a simple and effective way.

10. Von Restorff Effect

Definition: in a homogeneous set of items, you’re more likely to remember the odd one.

Application: Colour contrast or any other weird shape will bring into the light those elements which are important for the user to pay attention, such as calls to action or notifications.

Impact: by drawing the attention to certain key elements by placing focus on them does increase the likelihood that users will actually interact with your design’s most critical aspects.

 

Other UX Laws

UX Law Definition Application Impact
Law of Proximity Objects that are close to each other are perceived as related. Group related items together, such as form fields or menu options. Helps users easily find and understand related information, reducing cognitive load.
Law of Prägnanz People perceive complex images in their simplest forms. Simplify visual content and reduce unnecessary detail. Improves clarity and ensures users focus on essential information without distractions.
Law of Similarity Objects that look similar are perceived as part of the same group. Use consistent colors, shapes, and styles for elements with the same purpose. Creates visual coherence, making interfaces easier to understand and navigate.
Law of Common Region Elements are perceived as related if they are located within the same closed area. Place grouped items within distinct sections or boxes, such as related products. Strengthens visual grouping, helping users differentiate between distinct content areas.
Serial Position Effect People are more likely to remember the first and last items in a sequence. Place key information at the beginning and end of lists or menus. Enhances recall of critical items, improving navigation and user experience.
Law of Figure/Ground People instinctively separate objects from their background. Use contrasting colors or shapes to differentiate primary elements from the background. Improves focus and readability, making content more accessible and engaging.
Zeigarnik Effect People remember uncompleted or interrupted tasks better than completed ones. Use progress indicators to show incomplete steps in a multi-step process, like checkout. Encourages users to complete tasks, boosting engagement and conversion rates.
Pareto Principle (80/20 Rule) 80% of effects come from 20% of causes. Identify and focus on the features or elements that will have the most significant impact. Improves design efficiency by focusing resources on high-impact areas, enhancing usability.
Law of Closure People perceive incomplete shapes as complete. Use implied shapes or paths to guide the eye without extra visual clutter. Engages users and simplifies the design while maintaining structure and flow.
Law of Contiguity Users perceive elements that occur close in time as related. Pair instructions with actions (e.g., confirmation messages after a form submission). Creates a sense of cohesion, improving understanding and user flow.

Designing UX Laws Application

That is all well and good in theory, but in practice, the real value of UX laws comes in how such principles are applied when working on actual design projects. Having such laws integrated into the design process can contribute a great deal to usability, satisfaction, and engagement. Here comes a step-by-step guide on practical implementation together with some real-life examples showing the impact.

Designing UX Laws Application

1. Jakob’s Law in Navigation Design

  • Application: Apply patterns that people are already used to on your website or application design.
  • Example: A menu navigation at the top of the page, or a search bar on the right-hand side. Commonly used elements will help users become confident in where things are as they use the site.
  • Example: Most shopping websites, like Amazon, tend to be very standard in how their products are listed and ways of navigation. In continuing these patterns of familiarity, it allows users to grasp how to browse categories, view items, and check out much more smoothly.

2. Simplifying Choices through Hick’s Law

  • Application: Too much choice creates user paralysis, when the user would rather not choose at all. In order to avoid it, options should be combined or restricted to what the user is shown, at least in more complicated contexts like forms or product filters.
  • Example: The Spotify mobile application makes it easier for its navigators to use by categorizing the different kinds of music into playlists, genres, and moods. This structure will help users make decisions in terms of what to listen to without feeling overwhelmed with the number of options available in the application.

3. Miller’s Law in Information Display

  • Application: Chunking information breaks up information into manageable pieces, making it easier for users to process. Apply the visual hierarchy through headings, subheadings, and lists in placing the content appropriately.
  • Example: Material Design by Google suggests chunking information into cards to break down such complex content. This makes comprehension easier and allows users to process data without much hassle.

4. Call-to-Action Button Enhancement through Fitts’ Law

  • Application: Position highly used buttons, such as “Submit” or “Add to Cart,” in easy-to-reach locations. On mobile, consider the thumbreach zones, placing important actions within easy reach.
  • Example: Most mobile banking applications position key user actions-say, “Transfer” or “Deposit”-within the bottom third of the screen, which reaches your thumb. Such positioning of elements makes frequent usability features more accessible and reduces effort for the user.

5. Making Forms More Flexible with Postel’s Law

  • Variations in input, in particular for dates, phone numbers, and addresses, should be small. Be flexible in accepting different formats so that the user may not get frustrated and can be flexible.
  • For example, Booking.com does not limit its search feature to a specific date format; hence, clients from other regions are comfortably entering the dates in their format without generating errors. In this way, loads of users are accommodated with ease when inputting information.

6. Increase Emotional Engagement by Using the Peak-End Rule

  • Application: Design milestones along the process to create a great impression at the start, height of interactions, but most especially at the end.
  • Example: Onboarding-usually guiding the user through some initial setup in a friendly and easy-to-follow manner-makes for a very good first impression. Also, upon completion of a task, a thank-you screen shows warmth and enhances positive interactions.

7. Aesthetic-Usability Effect on Branding

  • Application: Ensuring the design elements are attractively and cohesively matched to the brand in order for it to look professional and more usable.
  • Example: The clean and modern design language which Apple pursues makes it both visually appealing while it’s functional at the same time. Due to its look, users want to explore the interface and engage with it while at the same time, it builds trust and reinforces usability.

8. Performance Improvement by Doherty’s Threshold

  • Use latencies less than 400 ms with sufficient feedback, such as spinning icons while waiting, to be displayed to the user.
  • Example: Google’s search page presents the results in hardly any time; in the case of longer queries, it presents the progress indication. This type of immediate feedback will retain users and their participation in further using the service.

9. Simplification of Complexity – Tesler’s Law

  • Application: Knowing which features in your product are superfluous and reducing them to make sure core functionality is clear and accessible.
  • Example: The Twitter design focuses on its core activity – posting and reading tweets. There is no peripheral feature, keeping the site intuitive and never overwhelming for the user.

10. Drawing Attention with the Von Restorff Effect

  • Application: Highlight relevant elements, such as calls-to-action or notifications, using contrasting colors or bold visuals.
  • For instance, Instagram uses bright colors for its notification icons. If there is some new activity, it catches the users’ Attention in a moment. In this way, this will make the user locate the important updates faster and without looking.

 

Why UX Laws Matter in Design?

UX laws integrated into design work confer the ability to create interfaces that become intuitive for users. Users who can easily get through a digital product through subtle visuals or patterns and behaviors are more satisfied and engaging.

Why UX Laws Matter in Design

UX laws are based on empathy and understanding of the user, giving the designer an unparalleled strategic advantage, as these provide a framework that assures the experiences will be user-friendly.

They will guide everything from the designing of simple buttons down to the complex navigation flows in order to ensure that at the end, the product is really functional, accessible, and intuitive.

Knowledge of these principles by designers can help optimize every step of the user’s journey, right from reducing cognitive load to simplifying interactions. It could be the creation of recognizable patterns for users who are used to such interfaces or simplification of hard choices.

UX laws equip a designer with ways to meet and even exceed user expectations that make interactions efficient and rewarding.

 

Challenges of Using UX Laws

While UX laws do provide productive frameworks that guide the designer in comfortable and user-friendly experiences, putting them into practice can be quite hard to apply to real life. Finding the right balance between theory and practice, adapting to various user needs considering project constraints-all these are required. There are many common challenges designers face while applying UX laws and some ways through which those challenges can be overcome.

Challenges of Using UX Laws

Balancing Several UX Laws

Challenge: In intricate designs, there come times when a designer feels that a lot of UX laws might apply simultaneously and at times even seem to conflict with each other. For example, Fitts’ Law states that the bigger and reachable any button is, the better it is. This often runs in conflict with aesthetic preferences or the need for a reduction of clutter as outlined under Hick’s Law.

The order of importance of the UX laws is going to vary depending on the project objectives, so if, for instance, the primary objective of the design has to do with rapid execution of tasks, then Fitts’ Law becomes more important in making sure that key actions are easy to access. In other cases, if the focus of design is to fall on ease of cognitive load, then it should lean more toward Hick’s Law in order to reduce choices.

Maintaining Flexibility with Postel’s Law

The challenge, of course, is that support for flexible user input, as advocated by Postel’s Law, is not always easy to implement technically. Absolute exactness in particular data entries is of great importance within the financial world or the healthcare world, thus the designers run the risk of accepting too many variations that may eventually damage data integrity.

Solution: Introduce limits on flexibility. For instance, accept input variations but standardize and normalize the entries behind the scenes. For instance, an address field may be able to handle several different formats but normalize them before storing them, hence striking a balance between flexibility and consistency.

Explaining Miller’s Law- Cognitive Overload

Problem: Although Miller’s Law states information should be chunked, having the information too fragmented can confuse a user rather than simplify the user’s experience. In particular, if the user needs to have a holistic view to do a task, such as comparing a set of products against each other or viewing complex instructions.

Solution: A clear hierarchy, judicious use of chunking. Chunk information so that where there is more detail, it’s easily disclosed by the user if they need to. Example: On a long product description, collapsible sections give users an overview but afford them the opportunity to dig deeper if they want to.

4. Applying UX Laws to Various Devices

Application of certain UX laws across devices is quite tricky. For instance, Fitts’ Law really stresses target size, but whatever works on desktop doesn’t quite make its way to mobile.

This would include designing responsively, adapting the design to the form of the device. On mobile, main actions should ideally sit within thumb-reachable zones, while larger target sizes would be required for desktops. Test your designs across devices to ensure the experience remains consistent and intuitive.

5. Using the Aesthetic-Usability Effect for Balancing Aesthetic Preferences

Problem: The more aesthetic designs may create the impression of higher usability among users. However, too much focus on aesthetics actually harms performance and functionality, especially on mobile.

Solution: Things need to be balanced between beauty and performance. Let aesthetics be a priority to only a reasonable extent that visuals enhance, not detract from, usability. Optimize image sizes, reduce animations, and avoid heavy elements that can make loading times slow. This will keep the design clean yet effective.

6. Tesler’s Law to Avoid Over-Simplification

Problem: Tesler’s law says to reduce gratuitous complexity, oversimplification kills features or reduces functionality such as the depth required in applications like data analytics.

Solution: Distinguish between what is considered “nice-to-have” and “must-have” features. While eliminating the unnecessary elements in simplifying them, retain the important aspects necessary in performing tasks. Through user testing, one can know what users consider important and what can be simplified without affecting usability.

7. Meeting User Expectations across Different Contexts

Problem: Jakob’s Law says consistency with user expectations, but such expectations may result from several factors related to demographic differences, cultural background, and even past experiences pertinent to the product being investigated.

Solution: Research what your target group prefers. Perform A/B testing to see what is best for your audience. Permit users to customize the interface to their taste.
