Hi 👋🏻 , UX Designers !

Welcome, aspiring UX designers! If you’re just stepping into the world of User Experience (UX) design, you’re in the right place. Today, we’re diving into the fascinating world of UX laws—principles that guide how users interact with products. These laws are the foundation of creating intuitive, user-friendly designs. Let’s explore these concepts with simple explanations and real-world examples.

Why UX Laws are Important

Understanding UX laws is crucial for anyone embarking on a UX design journey. These laws are derived from psychology and behavioral studies, providing insights into how users think and behave. Here’s why they are important and how they impact UX design projects:

Creating Intuitive Designs: UX laws help designers create interfaces that feel natural and intuitive. By adhering to these principles, you ensure that users can navigate your product effortlessly, leading to a smoother user experience.

Improving Usability: Following UX laws improves the usability of your design. It makes your product more accessible and easier to use, which is essential for user satisfaction and retention.

Enhancing User Satisfaction: When users find a product easy to use and navigate, their satisfaction increases. Happy users are more likely to return to your product and recommend it to others.

Reducing Learning Curve: Applying these laws minimizes the learning curve for new users. They can quickly understand how to interact with your product because it follows familiar patterns and behaviors.

Increasing Efficiency: Designs based on UX laws are more efficient. Users can complete their tasks faster and with less effort, which improves their overall experience and productivity.

Boosting Engagement: Well-designed interfaces that follow UX principles are more engaging. Users are more likely to spend time on your product, explore its features, and interact with it regularly.

By integrating these laws into your design process, you create products that are not only functional but also delightful to use. Let’s delve into the specific UX laws and see how they can be applied.

1. Hick’s Law

🙀 Definition:The time it takes for a person to make a decision increases with the number and complexity of choices.

🤖 The Principle: The more choices a user has, the longer it takes for them to make a decision.

🍽️ Example: Imagine you’re at a restaurant with a menu that has only five items. It’s easy and quick to choose what you want. Now, think about a menu with fifty items. You’d spend more time deciding, right? The same goes for UX design. Simplifying choices helps users make decisions faster.

🎲 Application: When designing a website or app, keep menus, options, and actions to a manageable number. For example, on an e-commerce site, categorizing products into clear, distinct groups makes it easier for users to find what they’re looking for.

2. Fitts’s Law

Definition: The time required to move to a target area is a function of the distance to the target and the size of the target.

The Principle: The time to acquire a target is a function of the distance to and size of the target.

Example: Imagine trying to click a tiny button on the far side of your screen. It’s not only hard to see but also takes longer to move your cursor to it. Larger buttons that are closer to where users naturally navigate are quicker and easier to interact with.

Application: Ensure important buttons and links are easily accessible and large enough to click without precision. Think of the “Submit” button on a form—it should be big and prominently placed to reduce friction.

3. Jakob’s Law

Definition: Users spend most of their time on other sites and prefer your site to work the same way as all the other sites they already know.

The Principle: Users spend most of their time on other sites, so they prefer your site to work the same way as all the other sites they already know.

Example: If most e-commerce sites have the shopping cart in the top right corner, users expect to find it there. Deviating from this norm can confuse them and disrupt their experience.

Application: Stick to familiar design patterns. Leverage common layouts, navigation structures, and interface elements. This familiarity breeds comfort and reduces the learning curve for new users.

4. Law of Proximity

Definition: Objects that are close to each other are perceived as more related than objects that are farther apart.

The Principle: Objects that are close to each other are perceived as related.

Example: On a form, placing labels close to their corresponding input fields helps users understand which label belongs to which field. If the labels are far away, it becomes confusing and frustrating.

Application: Group related elements together. For instance, in a user profile section, keep the name, email, and password fields close to each other. This visual grouping aids in quick comprehension and task completion.

5. Miller’s Law

Definition: The average person can only keep about seven (plus or minus two) items in their working memory.

The Principle: The average person can only keep 7 (plus or minus 2) items in their working memory.

Example: Think about trying to remember a long list of groceries versus a shorter one. The shorter list is much easier to recall. Similarly, users can only handle a limited amount of information at once.

Application: Break down complex information into smaller chunks. Use bullet points, headings, and concise text to avoid overwhelming your users. For example, when explaining features of a product, list them in brief, digestible points rather than long paragraphs.

6. Pareto Principle (80/20 Rule)

Definition: 80% of the effects come from 20% of the causes.

The Principle: 80% of the effects come from 20% of the causes.

Example: On a website, 80% of user interactions often come from 20% of its features. For instance, a blog might find that the majority of traffic goes to a few popular articles.

Application: Focus on optimizing the most used features of your site. Prioritize the design and functionality of elements that bring the most value to users. For an app, this might mean enhancing the usability of core features rather than spending time on less critical components.

7. Aesthetic-Usability Effect

Definition: Users are more likely to perceive aesthetically pleasing designs as easier to use.

The Principle: Users are more likely to perceive aesthetically pleasing designs as easier to use.

Example: Think of two coffee machines: one is sleek and modern, the other is old and clunky. Even if they function the same, most people will gravitate towards the more attractive one, believing it to be superior.

Application: Invest in visual design. A clean, visually appealing interface not only attracts users but also instills confidence in the product’s usability. For example, an elegant, well-designed homepage can make users feel more at ease and willing to explore further.


Understanding and applying these UX laws can significantly enhance your design process and create a more user-friendly experience. By considering how users think and behave, you can make informed design decisions that lead to more intuitive and enjoyable interactions. Keep these principles in mind as you embark on your UX design journey, and you’ll be well on your way to crafting exceptional user experiences.

Happy designing!
