Simplicity in design: how to create clear UX/UI experiences

Let’s take a random page, say a settings page, and add forty options on one screen. It might look comprehensive, but finding the right setting or deciding what to change can quickly become frustrating. Simplicity in UX/UI design addresses exactly this kind of friction.

However, an interface that feels effortless is rarely easy to build. It takes user research, hard decisions about what to prioritize, a deliberate visual hierarchy, and several rounds of testing. With UI and UX working together, the aim is to make the experience clearer without stripping away useful functionality. Below, we look at what simplicity really means and how to apply it without oversimplifying.

What is simplicity in UX/UI design?

Simplicity in UX/UI design means removing unnecessary complexity from a product while keeping it useful, clear, and focused on the user’s main goal. A simple interface lets people see what they can do, do it with as few obstacles as possible, and understand the result.

In his book Don’t Make Me Think, usability expert Steve Krug argues that interfaces should be self-evident, so users can understand what they’re looking at and how to use it without unnecessary effort.

That’s why the simplicity design principle applies to both layers of a product. In the user interface (UI), it shapes layout, typography, and controls. In the user experience (UX), it shapes flows, content, and the number of decisions on the way to a goal.

Why simplicity matters in UX/UI design

Every screen asks for some of the user’s attention. The less clutter there is, the easier it becomes to focus on what matters — and that's good for business, too.

It reduces cognitive load

Cognitive load is the mental effort a person needs to process information and act on it. When this load is too high (extra buttons or vague labels), it leads to more errors and slower reactions. But once a screen shows only what’s relevant to the task, users can focus on what matters. This connects directly to how psychology and UX influence user decision-making: people tend to choose the path that feels easiest, and a lighter interface guides them there more efficiently.

It helps users make decisions faster

More options usually mean slower choices. According to Hick’s Law, a principle from 1950s psychology research, decision time grows as the number of possible choices increases. On a pricing page with seven plans or a menu with twenty equally weighted items, users compare rather than buy.

Simple design reduces this delay by:

1. Narrowing the choice set: They show the options most people need and group the rest.
2. Recommending a default: A suggested plan or setting is highlighted.
3. Making the next step obvious: One clearly labeled primary action.

As a result, users move forward with confidence instead of second-guessing.

It improves usability and accessibility

Clear structure benefits everyone, and it matters most for people who process information differently. The W3C’s guidance on making content usable for people with cognitive and learning disabilities sets objectives such as helping users find what they need, focus, and avoid mistakes, as well as using clear and understandable content. Simple design supports these objectives and can help people with ADHD, non-native speakers, and anyone trying to complete a task while distracted.

If people have to guess what happens after every click, something in the design needs fixing.

It builds trust through clarity and consistency

First impressions form very quickly. In a study published in the International Journal of Human-Computer Studies, researchers showed participants website screenshots for as little as 17 milliseconds. Sites with low visual complexity and a familiar layout were rated as the most appealing.

But first impressions are only part of the story. A clear, consistent interface can also make a product feel more reliable over time. Whenever people meet something unpredictable, such as buttons that look different on every screen or links that open in unexpected places, they start to doubt the product.

What simplicity in design does not mean

It’s easy to misunderstand simplicity in design and end up removing things users actually need. Here's what to watch out for.

Simplicity is not minimalism

Minimalism is a visual style that uses limited colors, lots of space, and few decorative elements. Simplicity focuses less on visuals and more on usability: making the product easy to understand and utilize. The two often look similar. The difference is that a minimal interface can still be unintuitive. For example, when navigation hides behind an unlabeled icon or buttons lose their borders and look like plain text.

Simplicity is not removing important functionality

Cutting features is the fastest way to make a screen look simpler and one of the riskiest. If users need a function and can’t find it, the product becomes harder to utilize. A complex analytics tool or a professional editor can still feel simple when its features are well organized, grouped by task, and revealed at the right moment.

Simplicity is not making every interface look the same

Familiar conventions, such as a shopping cart icon in the top corner or navigation along the top or left side, help users orient themselves. Simplicity in design doesn’t require copying a generic template, though. A banking app, a design tool, and a children’s learning platform serve different users with different goals, so a simple solution should look different in each case.

Core principles of simple UX/UI design

Simple products tend to follow the same set of design principles that make them effortless for users, since each one removes a specific source of friction.

Clear visual hierarchy

Size, color, contrast, position, and spacing guide the eye to what to look at first, second, and last. With a clear hierarchy, people can scan a page and find the main action within seconds. When it’s not the case, every element competes equally for the user’s attention.

Limited choices and clear next steps

Showing every option at once rarely helps. A better approach is to define the one action most users need on a screen and make it visually dominant. As for the secondary actions, they should be available but quieter, for example, as text links or inside a menu.

Consistent interface patterns

A predictable interface means that the same element looks and behaves the same everywhere. If a blue button submits a form on one screen, it shouldn’t delete data on another. Taking into account two kinds of consistency, internal (within your product) and external (with platform conventions people already know), reduces the number of actions users need to learn.

Clear language and helpful microcopy

Good copy often removes the need for extra UI elements, such as tooltips or help pop-ups. This is a short overview:

• Precise names for actions: “Save draft” instead of “Submit.”
• Explanations for errors: “Password must contain at least 8 characters” instead of “Invalid password.”
• Drops filler: “Upload your file to continue” instead of “To proceed with the next step in this process, please upload your file.”

Thoughtful use of white space and negative space

White space, also called negative space in design, is the empty area between and around elements. It groups related items, separates unrelated ones, and gives important content room to stand out. In practice, it often does more to reduce visual noise than removing elements does.

Progressive disclosure

Progressive disclosure shows people only what they need at the current step and reveals advanced options when they ask for them. A photo editor might put basic tools like cropping, rotating, and filters upfront, while keeping more advanced options, such as curves and color channels, in a separate panel. That way, beginners can get started easily, and experienced users still have access to the tools they need.

How to achieve simplicity in UX/UI design

Now that you know the basics of simplicity in design, it’s time to learn how to put them into practice and create interfaces that feel clear, intuitive, and easy to use.

Start with user goals and key tasks

Before changing anything on screen, define what users come to do and which tasks matter most, as described in our complete guide to UX flow. This shows where people take detours, repeat actions, or get stuck, and you can decide what stays and what goes.

During discovery for Home Medix, a medical equipment e-commerce platform designed for older adults, our team identified confusing interactions and accessibility issues that could cause users to leave. These insights informed a simpler site structure, with clearer navigation, categories, and filters.

Remove visual noise and unnecessary steps

Once the key tasks are clear, review every element against one question: does it help the user complete this task? If there are any decorative graphics, repeated information, optional form fields, and confirmation screens, consider removing them. The same applies to steps: if a flow asks for information the product already has, that step can usually go.

It’s easy to keep adding things. The tricky part of simplifying is deciding what not to show.

Prioritize one main action per screen

Giving each screen one primary action draws attention to the task users came to complete. Secondary actions, such as “Save for later” or “Go back,” should remain available, just less prominent. For example, in our mood-tracking app, HowIFeel, we made logging a mood the central interaction. Users can record how they feel by selecting an emoji, without having to navigate a complicated flow.

Test the design with real users

A design that seems obvious to the team can confuse someone seeing it for the first time. To avoid this, usability testing is a great choice. It helps you learn where people hesitate, misread labels, or miss important controls. Professional user testing can make this process more systematic, with moderated or unmoderated sessions and prioritized recommendations.

Review and simplify continuously

Products tend to grow more complex with every release as new features and settings are added. Regular UX design audits use data from analytics, support tickets, and session recordings to identify unused features, abandoned flows, and screens that need rework, and then turn these findings into a prioritized list of improvements.

Simplicity in UX/UI design examples

Simplicity looks different depending on the task. In onboarding, it means helping users get started without unnecessary setup. In checkout, it comes down to making each step easy to complete. In a dashboard, it is all about showing the right information without overwhelming people. Here’s what that looks like in practice.

Simple onboarding flow

A simple onboarding gets new users to their first useful result as quickly as possible. Instead of a long tutorial before the product even opens, it asks only for essential information, applies sensible defaults, and explains features in context when the user first needs them. Everything else, such as profile details or notification settings, can wait until later.

Simple checkout or form experience

In a simple checkout, the user moves through a short, focused sequence without distractions. Typical decisions include:

• removing extra fields and asking for each piece of information once;
• validating fields as people type instead of after submission;
• formatting card numbers and phone numbers automatically;
• keeping a clear way back to the cart.

Each change reduces the chance that someone abandons the purchase over a small frustration.

Simple dashboard or navigation

Data-heavy products show that simplicity doesn’t depend on how much information a system handles. The key is organizing it around what users actually need. For our laboratory information system, we designed over 50 screens tailored to different lab roles and diagnostic workflows. By keeping navigation focused on everyday tasks, we made complex processes easier to follow without sacrificing essential functionality.

When simplicity can go wrong

Oversimplification happens when a team removes complexity users actually need. You can usually observe it in:

• Hidden navigation: key sections tucked behind a menu icon on desktop, adding clicks and making them less visible.
• Unclear icons: symbols without labels that users interpret differently, especially for less common actions.
• Missing context: short labels or empty states that leave the next step unclear.
• Oversimplified forms: single fields that merge different data, or removed hints that people need to enter information correctly.
• Features buried too deep: frequently used functions placed several levels down for the sake of a cleaner home screen.

In each case, the screen looks simpler, but the user has to work harder, which signals that simplification went too far.

Simplicity starts with the right UX decisions

Removing elements can make a screen look cleaner, but that doesn’t always make a product easier to use. True simplicity starts with understanding what people want to achieve, which tasks matter most, and which elements they need to complete them. A well-designed interface also relies on a clear visual hierarchy, familiar patterns, and straightforward language. Regular usability testing and UX audits help keep the experience simple as the product evolves.

To put these principles into practice, look at your product’s most common tasks. Can people complete them without unnecessary steps or confusion? Do they understand the labels and know what to do next? If each release makes the product harder to use, or support teams keep answering the same basic questions, it's time to review the UX and identify what needs to change.
