Laws of UX is a collection of best practices that designers can consider when building user interfaces. They are grouped into four categories below.
Rules of thumb for quick, efficient design decisions — Fitts’s Law, Hick’s Law, Jakob’s Law, and more.
Fundamental principles for intuitive interfaces — Doherty Threshold, Occam’s Razor, Tesler’s Law, and more.
How people perceive visual information — proximity, similarity, common region, and connectedness.
Patterns in judgment and memory — peak-end rule, serial position, Von Restorff, and Zeigarnik effects.
Some laws apply broadly across interfaces; others are more specific to certain products or audiences. Consider context and target users when applying them.
