Law of Similarity

Things that look similar to each other


Everyone knows similarity from every day life. Houses look familiar as everyone has seen a similar one before. Even parks might seem known because they look similar to another park someone was at before.

For UX designers the law of similarity can be very important, as it means that elements that have the same/similar visual appearance must have the same/similar function. Buttons for example should all have a similar appearance.

But this goes beyond a single website. The law of similarity can also be used over multiple solutions. The burger-menu for example is used across multiple websites and users recognise it again due to the similarity.

Visual Design

Visual design plays an essential role for the user experience of a product, software or service.
