The user interface (UI) is a critical part of any software product. When it’s done well, users don’t even notice it. When it’s done poorly, users can’t get past it to efficiently use a product.

To increase the chances of success when creating user interfaces, most designers follow interface design principles. Interface design principles represent high-level concepts that are used to guide software design. In this article, I’ll share a few fundamental principles.

The UI design principals are:

Place users in control of the interface

Good UIs instill a sense of control in their users. Keeping users in control makes them comfortable; they will learn quickly and gain a fast sense of mastery.

Make actions reversible – be forgiving

This rule means that the user should always be able to quickly backtrack whatever they are doing. This allows users to explore the product without the constant fear of failure — when a user knows that errors can be easily undone, this encourages exploration of unfamiliar options. On the contrary, if a user has to be extremely careful with every action they take, it leads to a slower exploration and nerve-racking experience that no one wants.
