Top 15 UX Design Principles to Improve Usability in 2025

The 7 core principles, defined by Peter Morville, are:

• Useful: The design must solve a clear problem.
• Usable: The design must be easy to navigate.
• Findable: All content in the design must be logically organized.
• Credible: The design must build trust through transparency.
• Accessible: The design should work for all abilities.
• Desirable: One must aim for aesthetically engaging designs.
• Valuable: The design should benefit users and businesses.

• Start with user research (surveys, interviews) to identify pain points.
• Simplify navigation with consistent patterns.
• Test prototypes early on to measure task success rates.
• Trim unnecessary features and focus on designing features that users need.

Following UX design principles leads to strong UX design. This in turn leads to fewer post-launch fixes and customer support requests.

These designs meet accessibility laws, (for instance, ADA, WCAG) and avoid legal risks. Intuitive interfaces also increase sign-ups, purchases, and retention.
