Full List of UX Laws
Let’s explore 19 UX Laws and their use examples, from Hick’s Law to the Law of Context. Understanding these principles can help you design user-friendly interfaces and experiences that are intuitive, engaging, and effective.
Hick’s Law
The time it takes to decide increases with the number of choices available. In UX design, this law reminds us to keep things simple and limit the number of options presented to users. ⚡️Example: An e-commerce website could limit the number of product categories on the homepage to avoid overwhelming users.
Fitts’s Law
The time it takes to reach a target with a pointing device (such as a mouse) depends on the distance to the target and the size of the target. In UX design, this law emphasizes the importance of making buttons and other clickable elements large and easy to find. ⚡️Example: A mobile app could make the “add to cart” button large and prominent to make it easy for users to click.
Jakob’s Law
Users spend most of their time on other sites, so users expect your site to work the same way as all the other sites they already know. In UX design, this law reminds us to follow established design patterns and conventions to make our websites more intuitive and easy to use. ⚡️Example: A news website could use a familiar layout and navigation structure to make it easy for users to find and read articles.
Miller’s Law
The average person can only keep 7 (plus or minus 2) items in their working memory at a time. In UX design, this law emphasizes the importance of breaking up complex tasks into smaller, more manageable steps. ⚡️Example: A software application could break up a long form into multiple steps to make it easier for users to complete.
Pareto Principle
80% of the effects come from 20% of the causes. In UX design, this law reminds us to focus on the 20% of features or functionality that will have the biggest impact on users rather than trying to do everything at once. ⚡️Example: A social media platform could prioritize the most popular features, such as posting and commenting, over less-used features.
Tesler’s Law
For any system, a certain amount of complexity cannot be reduced. In UX design, this law reminds us that there will always be some complexity in any system, but we should strive to minimize it as much as possible. ⚡️Example: A website could simplify the checkout process as much as possible while still gathering necessary information from users.
Aesthetic-Usability Effect
Users perceive attractive products as more usable. In UX design, this law reminds us that visual design and aesthetics play an important role in user experience. ⚡️Example: A mobile app could use a visually appealing color scheme and typography to make the interface more enjoyable to use.
Law of Common Region
Elements tend to be perceived into groups if they are sharing an area with a clearly defined boundary. In UX design, this law reminds us to use visual cues such as borders and white space to combine related elements. ⚡️Example: A website could use a border around the navigation menu to make it stand out from the rest of the page.
Law of Proximity
Elements that are close to each other tend to be perceived as a group. In UX design, this law reminds us to arrange related elements in close proximity to each other to convey a sense of hierarchy and organization. ⚡️Example: An e-commerce website could group product categories on the homepage to make it easy for users to find what they want.
Law of Similarity
Elements with visual similarities (such as shape, color, or texture) tend to be perceived as a group. In UX design, this law reminds us to use consistent visual design patterns throughout our interfaces. ⚡️Example: A mobile app could use a consistent color scheme throughout
Law of Closure
The brain tends to fill in missing pieces to form a complete picture or shape. In UX design, this law reminds us to use visual cues such as borders or enclosing shapes to make the interface feel more organized and complete. ⚡️Example: A website could use a box around related options or features.
Law of Continuity
The brain tends to perceive elements in a continuous, smooth flow. This law in UX design reminds us to use smooth transitions and consistent design patterns throughout our interfaces to make them more coherent and user-friendly. ⚡️Example: A mobile app could use a consistent design pattern for all its buttons, with smooth transitions between screens.
Law of Figure/Ground
The brain tends to separate elements into a foreground (figure) and a background (ground). In UX design, this law reminds us to use contrast and visual cues to highlight important elements and make them stand out from the background. ⚡️Example: A website could use a bold font or contrasting color for important text or buttons.
Law of Feedback
Users must receive clear and immediate feedback when interacting with a product. In UX design, this law reminds us to provide clear feedback to users, such as confirmation messages or progress indicators. ⚡️Example: A mobile app could show a loading indicator while a user’s data is being processed.
Law of Similarity
Elements that are similar in size, shape, or color tend to be perceived as a group. In UX design, this law reminds us to use consistent design patterns and visual cues to make related elements look similar and help users understand the relationship between those elements. ⚡️Example: A website could use a consistent color scheme for all its buttons and links.
Law of Expectation
Users have certain expectations of how a product or interface should work based on past experiences. In UX design, this law reminds us to follow established design patterns and conventions to make our products more intuitive and easy to use. ⚡️Example: A mobile app could use familiar icons and gestures to make navigating easier for users.
Law of Simplicity
The simplest solution is usually the best. In UX design, this law reminds us to simplify interfaces as much as possible while still meeting users’ needs. ⚡️Example: A web application could use a minimalist design to make the interface easy to use and understand.
Law of Visibility
The more visible an element is, the more likely users will notice it. In UX design, this law reminds us to use visual cues such as color, size, and placement to draw users’ attention to important elements. ⚡️Example: An e-commerce website could use a bold color or large font for a limited-time sale.
Law of Context
The meaning of an element can be influenced by the context in which it appears. In UX design, this law reminds us to consider the context in which our products will be used and ensure our interfaces are appropriate. ⚡️Example: A mobile app for weather forecasts could use location data to provide more relevant and contextualized information.
