Card Sorting

This method asks users to organize content into groups with labels. It is often used to create the information architecture of a web site or menu system.

Two variants:

  • Open card sorting. Users are allowed to cluster content items as they see fit. They then propose labels for the clusters.
  • Closed card sorting. Users are given a set of labels. They then place each content item with the label that matches best.

Mathis covers these methods in chapter 8.

Items for discussion

  • What information does card sorting provide?
  • Is it a user research method or a design method?
