Your users are judging you whether you like it or not and the first impression is everything. You have maybe only a few seconds to get your message across, allowing your customer to learn more about you and your product. Designing an effective user interface (UI) is critical to the success of any mobile app or website. The following ten UI design principles are the best guideline if you’re searching for a way to create an engaging and user-friendly platform that meets the needs of your audience.


A simple UI design allows users to quickly and intuitively navigate an interface, reducing user frustration and increasing engagement. Maintaining consistency throughout the design, such as using the same visual style for buttons, icons, and menus, further enhances the user experience.

Example: Twitter’s user interface features a simple design with consistent visual elements that allow users to easily navigate and engage with the platform.

User Needs

Your user’s needs are the exact reason why you’re designing a UI, which means it’s a high priority to create an intuitive and user-friendly design. Consider user habits, preferences, and behavior patterns when designing the interface to make it as intuitive as possible.

Example: Amazon’s UI is designed to prioritize user needs, featuring personalized product recommendations based on user behavior and preferences.


Consistency in the UI design is a great way to easily enhance the user experience and create trust in your brand. Start by ensuring that all aspects of the design, including layout, colors, and fonts, are consistent throughout your platform.

Example: Google’s UI maintains consistency across all its products and services, featuring a simple and consistent design that allows users to quickly navigate and engage with the platform.

Clear Feedback

Providing clear feedback to users when they interact with your product is necessary for reducing user frustration and improving usability. Error messages or highlighting selected items can help users understand their actions and reduce mistakes.

Example: LinkedIn’s UI provides clear feedback by highlighting selected items and displaying error messages when necessary, improving usability and reducing user frustration.

Visual Hierarchy

Creating a visual hierarchy in the UI design draws attention to your CTA (Call to Action), improving overall consistency, and usability. This can be achieved through the use of color, size, and contrast.

Example: Apple’s UI design features a clear visual hierarchy that draws attention to the most important information, such as the call-to-action buttons, making it easier for users to engage with the platform.

Readable Fonts

Using readable fonts is one of the most overlooked principles and if left unchecked it could lead to users not being able to read and comprehend the information on your platform. Sans-serif fonts are recommended for body text, and serif fonts are recommended for headings. Font size is also important, especially on mobile devices.

Example: Medium’s UI features readable fonts that are easy to read on both desktop and mobile devices, improving the overall user experience.

Incorporate White Space

There’s a lot you want to say and you’re not sure how to say it, so you add all the information you possibly can into one page. Now you’re left with little to no white space, making it difficult for users to differentiate between different sections. Instead, utilize white space to improve readability and create a visual break.

Example: Dropbox’s UI design incorporates white space, creating a clean and organized look that makes it easy for users to navigate and engage with the platform.


Ensuring that your apps are accessible for users with different abilities, such as those with visual impairments or motor disabilities, is a wonderful opportunity to incorporate features such as keyboard navigation and alternative text for images to make your digital products more accessible.

Example: Microsoft’s UI design incorporates accessibility features such as high contrast mode and voice control, making it easier for users with different abilities to use the platform.

Test and Iterate

Before launching you can assure that there will be bumps along the way, but you can be prepared to address those concerns during the testing and iterating the UI design. This stage identifies any flaws and allows you to make the necessary changes to ensure that your app is user-friendly and meets the needs of your audience.

Example: Airbnb’s UI design undergoes extensive testing and iteration to ensure that it meets the needs of its users and provides a seamless user experience.

Stay Up-to-Date

Staying up-to-date with the latest UI design trends and tech is the fun part. This is where you can invest in Research & Development to find the latest and greatest tools to deliver a higher quality user experience.

Example: Twitter updated its UI mobile design in 2021 to include a new feature called “Fleets”, which allowed users to share temporary tweets that disappear after 24 hours.
