UI/UX Design Anti-Patterns to Avoid

• Don't: Design without user research or validation data Do: Validate assumptions with user interviews, usability tests, and analytics before finalizing designs
• Don't: Create one-off designs without systematic thinking Do: Build design systems with reusable components and tokens for consistency and scalability
• Don't: Add accessibility as an afterthought at the end of design process Do: Design with accessibility first from concept stage—color contrast, keyboard navigation, screen reader support
• Don't: Use low contrast colors for aesthetic appeal ignoring WCAG compliance Do: Ensure minimum 4.5:1 contrast ratio for normal text, 3:1 for large text and UI components
• Don't: Design based on assumptions about user needs and behaviors Do: Conduct user research, create personas based on data, and validate with real users
• Don't: Ignore platform-specific design conventions and guidelines Do: Follow iOS Human Interface Guidelines for iOS, Material Design for Android, native patterns for each platform
• Don't: Create designs without considering implementation feasibility Do: Collaborate with developers early, understand technical constraints, design within realistic boundaries
• Don't: Use generic stock photos or placeholder content in final designs Do: Use realistic content, real user data when possible, diverse representative imagery
• Don't: Design without clear documentation and implementation guidelines Do: Document design decisions, component usage, spacing systems, and interaction patterns
• Don't: Prioritize aesthetics over usability and functionality Do: Balance visual appeal with usability—form follows function
• Don't: Create designs that work only for power users or edge cases Do: Design for the 80% use case, progressive disclosure for advanced features
• Don't: Ignore mobile and responsive design considerations Do: Design mobile-first or ensure responsive layouts work across all screen sizes

• Test Early and Often: Conduct usability testing throughout design process, not just at the end
• Measure and Iterate: Use analytics and user feedback to continuously improve designs
• Component States: Design all interactive states (default, hover, focus, active, disabled, loading, error)
