1. Simplicity

Making applications that are engaging requires simplicity. It is one of the key elements of UI/UX design principles. A straightforward interface is simple to use and comprehend. Adopt a minimalistic style for your design. Eliminate anything superfluous that does not advance the user’s objectives. Give clear instructions for navigation. Use familiar icons and terms. Make good use of whitespace to cut down on distractions and draw attention to important details.

As an example, think about the Google home page. With its clear navigation and uncluttered design, it is a shining example of simplicity. Google makes sure that people can concentrate on their main task, which is searching, by reducing distractions.

2. Consistency

Users can learn and anticipate how to use an application with the help of consistency. Establish a design system with elements, colors, and fonts that are all consistent. Utilize common elements, such as menus and buttons, consistently throughout the application. Make sure comparable interactions result in comparable results.

For instance, it is well known that Apple’s ecosystem is reliable. The design elements are the same whether you are using an iPad, iPhone, or Mac. This is why switching between devices is a seamless experience. 

3. Feedback

User feedback enables application owners to conclude the effects of their actions. To indicate actions, use visual signals such as color changes or animations. Also, give loading indicators so users can see that the application is working. Provide solutions along with clarified error messages.

As an example, Dropbox ensures that users are aware of the status of their uploads. They provide instant visual feedback and progress indicators when they upload a file.

4. Accessibility

Ensuring accessibility in application design guarantees that all users can engage with it. Verify that a keyboard can be used to navigate the application. Moreover, provide appropriate HTML tagging and ARIA labels to assist screen readers. To improve readability, use high contrast between the background and text colors.

Many accessibility features, such as high contrast modes and screen reader support, are available in Microsoft Office products. This enables users with a variety of disabilities to use the software.

5. Usability

Usability is one of the most important UI/UX design principles. Making an application easy to use is what usability is all about. To find usability problems, test your product with real users. Also, facilitate a seamless onboarding experience for users. For difficult tasks, provide tooltips and clear instructions.

For example, Slack provides an excellent onboarding experience. They provide a thorough onboarding guide that explains how to use the platform effectively.

6. Visual Hierarchy

A visual hierarchy directs users to the most crucial information first. To draw attention to important components, use font weight and size. Also, put crucial components in eye-catching locations, such as the top or middle of the screen. To highlight important areas, use contrast and color.

Newspapers make good use of visual hierarchy by using bold and large fonts. They use large, weighted fonts for headlines and smaller fonts for less important content. By doing this, the reader can navigate the content easily. 

7. Aesthetics

Designs that are visually appealing increase user engagement and satisfaction. Select a unified color scheme that is representative of your company. Moreover, use readable and eye-catching typefaces. To improve the design, add eye-catching graphics and photos.  

As an example, Instagram creates an engaging user experience. It combines a visually appealing and cohesive color palette with high-quality images and easily navigable fonts.

8. Performance

Performance has a big influence on the user experience. To speed up load times, write clear, well-optimized code. Use caching techniques to increase performance. UI/UX design principles ensure the app works well and is responsive across all platforms.

For example, Amazon’s website has optimized performance. This leads to responsive design and fast load times. As a result, it is easy to shop on desktop and mobile devices.
