What is Miller’s Law? – The Psychology of Design (3/7)

Miller’s Law predicts that the average person can only keep 7 (± 2) items in their working memory.


In 1956, a psychologist, George Miller performed research in which he found what he believed to be the limit of the human ability for processing information. He found that most people stored 7 things plus/minus 2 in their short-term memory.


Miller’s Law directs us to use chunking to organize content into more manageable groups. This helps users process, understand and memorize more easily.

This was particularly significant for first-time users. Because they haven’t had the time to encode the information into long-term memory.

The law also highlights the importance of foresight and proper planning in the design process, because as you add more features to a product — your interface must be able to accommodate those new features without breaking the visual foundation of what you built. Rebuilding a foundation takes immense time and resources.
