Achieving UX Success: 3 Key Design Laws

Graphic showing design examples

Creating a great user experience requires understanding and implementing fundamental design principles. In this blog post, we'll explore three key laws that can significantly impact UX success: Miller's Law, Jakob's Law, and the Aesthetic-Usability Effect.

Miller's Law, introduced by psychologist George Miller, reveals the limitations of our working memory. By grouping information into meaningful chunks, we can optimize content organization and enhance user comprehension. Remembering around seven pieces of information at a time, users can better absorb and retain content when presented in manageable segments.

Jakob's Law emphasizes the importance of adhering to established design patterns and conventions. Users spend most of their time on other websites, and they expect familiar functionality. By following commonly recognized symbols, layouts, and workflows, designers can provide a sense of familiarity while still incorporating unique elements to meet clients' needs.

The Aesthetic-Usability Effect, discovered by researchers Masaaki Kurosu and Kaori Kashimura, highlights the impact of aesthetics on usability. Beautifully designed interfaces evoke positive responses and enhance perceived usability, even when minor usability issues exist. While aesthetics can captivate users, designers must ensure that functionality remains at the core of the design to maintain long-term success.

Understanding and implementing these design laws can significantly improve the user experience. By organizing content effectively, adhering to established conventions, and balancing aesthetics with functionality, designers can create intuitive and visually appealing interfaces that engage and delight users.

Unlock the potential of these design laws to elevate your UX game and achieve success in creating exceptional user experiences.
