1. JAKOB’S LAW

Users spend most of their time on other sites. This means that users prefer your site to work the same way as all the other sites they already know. Websites do better the more standardized their design is.

2. FITT’S LAW

The time it takes someone to select an object in the screen depends on how far the cursor is from the object and the size of the object.

3. MILLER’S LAW

The average person can only keep 7 (plus or minus 2) items in their working memory.

• Proximity helps users understand and organize information faster and more efficiently.
