What is a closed card sort?

With a closed card sort, participants sort a list of items into predefined categories. They cannot update category names or add additional categories.

When should you conduct a closed card sort?

  • Testing an existing navigation structure: are my current category names understandable? Are there categories that aren't used by the users?

  • Leverage a closed card sort when adding new items into the existing structure to see how people fit new cards into existing categories.

  • You can also used closed card sorting to verify the labels that participants created during open card sorting.
