User-driven grouping and labeling reveals natural patterns in your content. Optimal’s card sorting helps you analyze these patterns, compare open vs closed sorts, and improve your information architecture and navigation with real users.
Use card sorting when...
From complex enterprise dashboards to public websites, card sorting helps teams bring structure to messy content.
Not necessarily. Optimal guides you through setup, and visual analysis makes it easy to understand the results, even if you’re new to research.
Most teams see meaningful patterns with 30-50 participants, depending on how diverse your audience is. The more complex your content, the more participants you may want to include.
In an open sort, participants create their own categories and labels, which is great for discovering mental models and understanding how participants think about your content. In a closed sort, they sort cards into predefined groups, ideal for validating an existing structure.
Yes. Card sorting works for any structured content, like mobile apps, dashboards, intranets, help centers, and more.
