Information Architecture Sorting
What is Information Architecture Sorting?
Information Architecture Sorting is a user research technique used to organize and categorize information in a way that makes sense to users. It involves asking participants to group related items or concepts together, helping designers create intuitive navigation structures and content hierarchies for websites, apps, or other digital products.
Synonyms: Card Sorting, IA Sorting, Content Categorization, Information Organization, Website Structure Testing

Why Information Architecture Sorting is Important
Information Architecture Sorting is crucial for creating user-friendly digital experiences. By understanding how users naturally group and categorize information, designers can:
- Improve website navigation and findability
- Reduce user frustration and cognitive load
- Increase user engagement and satisfaction
- Enhance overall usability of digital products
How Information Architecture Sorting is Used
Researchers typically use two main methods for Information Architecture Sorting:
- Open Card Sorting: Participants group items into categories they create themselves.
- Closed Card Sorting: Participants sort items into predefined categories.
The process usually involves the following steps:
- Prepare a list of items or concepts to be sorted
- Recruit participants representative of the target audience
- Conduct the sorting exercise (either in-person or online)
- Analyze the results to identify patterns and trends
- Use insights to inform the information architecture design
Examples of Information Architecture Sorting
- E-commerce Website: Sorting product categories and subcategories to create an intuitive navigation menu.
- Mobile App: Organizing features and settings into logical groups within the app's menu structure.
- Intranet Design: Structuring internal documents and resources in a way that makes sense to employees across different departments.
Frequently Asked Questions
- What's the difference between open and closed card sorting?: Open card sorting allows participants to create their own categories, while closed card sorting uses predefined categories.
- How many participants are needed for an effective Information Architecture Sorting study?: Typically, 15-20 participants per user group are recommended for statistically significant results.
- Can Information Architecture Sorting be conducted remotely?: Yes, there are online tools available that allow for remote card sorting exercises, making it easier to reach a diverse group of participants.
- How does Information Architecture Sorting relate to site mapping?: The insights gained from sorting exercises often inform the creation of site maps, helping to structure content in a user-centric way.
