Sort Types

Different ways to learn how users think

Choose the right sort type for your research question — or combine them in a single study.

Open sorting

Users create their own groups. Best when you're starting from scratch.

Closed sorting

Users sort into your categories. Great for testing an existing structure.

Hybrid sorting

Start with your categories, let users refine them.

Priority sorting

Understand what matters most, not just where things belong.

Mobile First

Works the way users actually use it

People don't sit at desktops to do research tasks. Your study shouldn't expect them to.

Cards appear in different orders to avoid pattern bias.

Deeper input

Users don't just group things — they show what matters most.

Frequently Asked Questions About Card Sorting

What is card sorting in UX research?
Card sorting is a research method where participants organize topics or items into categories that make sense to them. It reveals how users mentally group information, helping teams design intuitive navigation, menus, and information architecture.
What types of card sorts can I run?
You can run open sorts (participants create their own categories), closed sorts (participants sort into predefined categories), hybrid sorts (mix of both), and ranked sorts (participants prioritize items within groups). Each type answers different research questions.
Do participants need to install anything?
No. Card sorts run entirely in the browser on any device — desktop, tablet, or phone. Participants simply click a link and start sorting. No downloads, no plugins, no friction.
How does the analysis work?
Results include agreement matrices showing which groupings are unanimous vs controversial, automatic grouping of similar category labels, and full session recordings with participant audio so you can understand the reasoning behind each sort.
How many participants do I need for a card sort?
For most card sorts, 15–30 participants give statistically meaningful results. We can recruit niche audiences matched to your exact criteria and deliver first participants within 48 hours.
