UX Laws & Principles
Research-backed UX laws, principles, and methods connected to real insights
Aesthetic-Usability Effect
Users often perceive aesthetically pleasing design as more usable and are more tolerant of minor usability issues in beautiful interfaces.
Law of Closure
People tend to perceive incomplete shapes or forms as complete by filling in the gaps with their mind.
Law of Common Region
Elements located within the same closed region are perceived as grouped together.
Law of Continuity
Elements arranged in a line or curve are perceived as more related than elements not on the line or curve. The eye tends to follow smooth, continuous paths.
Law of Proximity
Objects that are close to one another tend to be grouped together and perceived as a unit.
Law of Prägnanz
People will perceive and interpret ambiguous or complex images in the simplest form possible. Also known as the Law of Simplicity or Law of Good Figure.
Law of Similarity
Elements that share similar visual characteristics (color, shape, size, etc.) are perceived as related and grouped together.
Law of Uniform Connectedness
Elements that are visually connected (through lines, colors, shapes, or other visual links) are perceived as more related than elements that are not connected.
Von Restorff Effect
Items that stand out from their surroundings are more likely to be remembered than items that blend in. Also known as the Isolation Effect.
