Laws of UX

The Laws of UX are a set of principles developed by designer Jon Yablonski to guide the creation of effective and user-friendly interfaces.

The laws are based on research and best practices in user experience design and can be applied to a wide range of digital products, including websites, apps, and software. The laws include the following:

  1. Hick’s Law: The time it takes to make a decision increases with the number and complexity of choices.
  2. Fitts’s Law: The time it takes to move to a target is based on the size and distance of the target.
  3. Jakob’s Law: Users spend most of their time on other sites, so they expect your site to work the same way as those they already know.
  4. Law of Proximity: Objects that are near to each other are perceived as related.
  5. Law of Similarity: Objects that share visual similarities, such as shape or color, are perceived as related.
  6. Law of Closure: People tend to perceive incomplete shapes as complete.
  7. Miller’s Law: The average person can only keep 7 (plus or minus 2) items in their working memory at once.
  8. Pareto Principle: 80% of the effects come from 20% of the causes.

By following these laws, designers can create interfaces that are intuitive, easy to use, and meet the needs of their users.
