Principles of Good UI Design

Learn key principles like consistency, simplicity, and feedback to create intuitive and effective user interfaces.

Key UI Design Principles

Master these fundamental principles to create user interfaces that are intuitive, efficient, and enjoyable to use.

Consistency

Maintain uniform design elements and patterns throughout your interface to reduce cognitive load and improve learnability.

Example: Using the same color for all primary action buttons across your application.

Simplicity

Eliminate unnecessary elements and focus on essential functionality to create clean, uncluttered interfaces.

Example: A minimalist login form with only username and password fields.

Feedback

Provide clear and immediate feedback for user actions to confirm that their input was received and understood.

Example: A success message after submitting a form or a loading spinner during processing.

Visibility

Make important functions and options visible and easily discoverable without requiring users to search for them.

Example: Placing the search bar prominently at the top of the page.

Constraints

Design interfaces that guide users toward correct actions and prevent errors by limiting available options.

Example: Disabling the submit button until all required fields are filled.

User Control

Empower users by giving them control over the interface, including the ability to undo actions and customize their experience.

Example: Providing an undo option after deleting an item.
