Card-Based IA organizes content into discrete, self-contained units (cards) that users can scan, compare, and interact with independently. Each card contains a preview or complete piece of content. Think Pinterest boards, Trello cards, or product grids. Great for heterogeneous content where items are equal in hierarchy.
Use card-based IA for content discovery (Pinterest, products, articles), dashboards (metrics, widgets), collections (team members, projects), or when content has similar importance but different types. Perfect for responsive design—cards reflow naturally on mobile. Avoid when content has strict hierarchy or sequential flow (use hierarchical or sequential IA instead).
