Card sorting allows you to discover how your users categorize and understand information. It's a great way to understand how your users think about the structure of your design.
Card sorting is useful to:
- Validate how people perceive information on a website or app.
- Understand where users expect certain content to be found.
- Get inspiration for labeling and grouping content.
- Segment how different user groups understand the content.

- While there's no hard limit on the number of cards/categories you can include in a Card Sort, we'd recommend limiting them to avoid overwhelming your testers.
- To avoid bias, you have the option to shuffle cards and/or shuffle categories so that they're presented to testers in random order.

Create a card sorting block
Here's how to add a card sorting block to your maze:
- Open your draft maze, or create a new one.
- In the draft maze, choose Card Sort from the list of blocks.
Customize your card sorting instructions
You can use the default title and instructions you see in the preview. To add your own, enable the Customize instructions toggle.
Set the card sorting type (open vs. closed)
With Maze, you can run both open and closed card sorts. Hybrid card sorting is not currently supported — if this is something you'd be interested in, please let our team know!
- Closed: Testers group cards into predefined categories. This method works well at later stages of a project, as it allows you to evaluate whether already established terminology and structures are intuitive to your users.
Open: Testers group cards into categories they create. This more flexible approach works well in the early/exploratory stages of a project, when you're looking to get a more accurate grasp of your users' mental models for grouping and labeling content.
Open card sorting is a paid plan feature.
Depending on the complexity of your project, it might make sense to use both approaches iteratively: start with an open card sort to discover how testers categorize and label your content, then at a later stage move to a close card sort to validate the decisions you’ve made based on the open card sort data.
To set the card sorting type, click the Closed or Open toggle in the maze builder.
Add and edit your cards
Click + Add cards to add the cards to be sorted (at least 1).
To add cards individually, click + Add new card, type the name of the card, and press Enter.
To add a batch of cards, click Add in bulk and paste the cards, separated by a comma or a new line.
To save, click Done.
To edit existing cards, click + Edit to open the card editor.
Click each card to edit it. Click and drag to change the order of the cards.
Open the card editor to access the following settings:
If needed, enable Shuffle cards to present cards in random order. This might be helpful to reduce bias.
Allow participants to continue without completing
If needed, enable Allow participants to continue without completing to allow participants to continue without having to sort all cards.
This might be helpful to prevent skewed results caused by testers placing cards on a random category (for instance, if they're unsure what a card means or where it should be placed) in order to move on with a maze.
Require participants to rank cards
If needed, enable Require participants to rank cards to prompt testers to rank cards according to preference or priority. Learn more here: Ranking items using a Card Sort block
To delete cards, open the card editor and click the Delete () icon next to each card name. To delete cards in bulk, click the More () menu and select Delete all cards.
Add and edit your categories (closed card sorting)
Click + Add categories to add the categories into which the cards should be sorted (at least 2).
Click + Add new category to add categories individually.
To add a batch of categories, click Add in bulk and paste the categories, separated by a comma or a new line.
To save, click Done.
To edit existing categories, click + Edit to open the category editor.
Open the category editor to access the following settings:
If needed, enable Shuffle categories to present categories in random order. This might be helpful to reduce bias.
To delete categories, click the Delete () icon next to each category name. To delete categories in bulk, click the More () menu and select Delete all categories.
