10 fundamental UI/UX design skills and traits
A great UX designer understands their users' needs and isn’t afraid to step into their shoes to produce a great digital experience.
However, it’s more than just a mindset. Here are some fundamental UX/UI design skills and why they’re so important.
6 hard skills for UI/UX designers
Hard skills are technical skills that UI designer candidates can show in practical tests. Your recruits need these essential skills to actually perform the roles you expect of them.
1. Design skills
A great UI/UX designer knows how to create product designs whose visual communication sends a message, evokes emotions, and meets the user's needs.
A candidate with excellent design skills is talented in:
Color theory: A good knowledge of color theory helps a designer create contrast and hierarchy and evoke certain emotions
Typography: A well-chosen font, weight, and spacing can make all the difference in readability
Composition: Talented UI/UX designers understand the principles of visual weight, balance, and rhythm, and how to use them to create layouts
2. Information architecture
Information architecture (IA) is all about organizing content so it’s easy to understand, follow, and act on. It also helps to keep people on-site.
Research shows that attention spans are decreasing. Time spent on web pages is decreasing, and bounce or “quit” rates are increasing across industries.
A good UX designer should have strong IA skills to create a digital interface with clear buttons and links to guide users to their desired destinations.
3. Wireframing and prototyping skills
UI/UX designers use wireframes to build app and site page structures and plan functionality.
Building wireframes and prototype models helps designers present visually appealing, easy-to-follow ideas while discovering pain points early in the design process.
These skills help designers create working design models for checks with team members and stakeholders before launching the final product.
4. Software skills
The following software skills are ideal for UX designers because they help them turn their ideas into interactive designs:
Graphic design software: Tools like Adobe Illustrator help designers make graphic elements and complete visual prototypes
Wireframing and prototyping software: To test the design and bring their UI ideas to life, competence in using prototyping tools like Sketch, Adobe XD, and Figma is ideal
User research software: By using tools such as Survey Monkey and UserTesting, skilled designers can collect feedback and analyze user data
UI/UX design surveys reveal that Sketch is the most preferred design tool for wireframing and user interface design, while many also use Figma and Adobe XD.
5. Research skills
With varied methods for UX research, designers learn about how users interact with digital products and what features are valued most:
Surveying: Collecting data about the target audience’s attitudes, preferences, and behaviors
Usability testing: Watching users interact with products to find areas for improvement
User interviews: Learning about users’ experiences, motivations, and opinions and getting in-depth insights
A/B testing: Testing two different versions of a design to see which one performs better
Analytics tools: Tools like Google Analytics gather data on user behavior, including how long people stay on a page
6. Coding skills
A basic understanding of coding languages helps designers communicate with developers and understand technical limitations.
Understanding the basics of JavaScript, Python, or CSS also helps designer applicants maintain agility and adaptability.
For example, a hiring company might promote a designer with coding skills into a UX engineering role.
4 soft skills for UI/UX designers
UI/UX designer soft skills are interpersonal traits that help people collaborate, think creatively, and manage workloads.
7. Problem-solving
UI/UX designers create designs that solve real-world problems for their users. The best recruits genuinely enjoy critical thinking and solving puzzles!
Here are some factors they might consider:
Understanding the problem: Designers must research and gather user feedback to analyze problems
Ideation: With a clear understanding of a problem, designers brainstorm, sketch, create mood boards, and collaborate with team members
Testing and iteration: Designers test design solutions with users, creating interactive prototypes and testing usability
Being adaptable: The best designers are willing to try new ideas if solutions don’t work right away
8. Empathy
Empathy is an important skill that helps designers understand their users' needs and emotions to create more effective and user-friendly products. This way, designers better understand their frustrations and challenges and create user-centered designs that address these issues.
This is one of several soft skills for UI/UX designer roles that are difficult to measure without testing. Further down, we show you how personality tests can help you assess this important trait.
9. Communication
For the best project results, UI/UX designers must have effective communication with others.
Here are some people UX designers communicate with regularly:
Clients: Designers must engage in active listening for the client’s needs, then explain design decisions clearly and convincingly before creating and presenting design mockups
Developers: Collaborating with developers and product managers helps to make sure projects are practical, on budget, on time, and satisfying business goals
Team members: Designers make sure everyone is on the same page by participating in team meetings and providing regular updates for project management
Users: Communication also comes in the form of UX writing, which requires the designer to communicate information concisely through the interface
Strong communication skills help build trust and understanding with clients and team members, too.
10. Time management
UI/UX designers with time management skills excel at prioritizing their workflow tasks. They understand which design project elements need the most attention and easily hit their targets.
These skills also help designers manage their stress levels to avoid burnout. Reducing burnout is a must, with 57% of US employees experiencing “moderate” to “very high” burnout levels.
