Affordance

Affordance is a design principle describing how an object’s attributes suggest its function. In UX/UI, it helps users intuitively understand how to interact with an interface without needing explicit instructions.

A button that looks clickable, a slider that appears draggable, or a text field that invites typing are all examples of affordances. These cues reduce cognitive load, allowing users to act quickly and confidently.

In product management, understanding affordance ensures that features are not only functional but also discoverable. A feature buried behind unclear controls can fail to deliver value, even if it is technically sound.

Affordances can be perceived (what the user thinks is possible) or actual (what is truly possible). Good design aligns both, so expectations match reality. Mismatched affordances can cause frustration, such as a decorative element that looks like a button but does nothing.

Digital products often use familiar metaphors, like a trash can icon for deletion, to create strong affordances based on user experience from other systems. These patterns become part of design systems to maintain consistency.

Mastering affordance means designing elements that clearly communicate their purpose, guiding users toward successful interactions without the need for extra explanation.
