One of the biggest questions in running card sorts is how many cards and users to include. In this video, learn what influences the right number and how to come to the right conclusion for your project.
- You can do as many or as few cards in a sort as you like.…The sweet spot depends on what you're trying to learn,…whether you're doing a moderated or unmoderated test,…and how complex the cards or concepts you're testing.…The more complex the cards and the more surrounding…discussion you hope to have,…the fewer cards you'll want to include.…Typically, you want to aim to have moderated sessions…be about 20 minutes of pure sorting…and at least 20 minutes of conversation.…The best way to know if you've hit the goal…is to do a pilot test with a colleague.…However, if you're working on a very complex system,…you may need to have more cards or you may need…to allot more time for a discussion…in order to get useful results.…
If you do an unmoderated study,…you'll want to aim for about 15 minutes of sorting.…If the session is too long, participants may start…to get burnt out and become less attentive.…The analysis will also be more difficult with more items.…If you're doing a closed card sort…with straightforward categories,…
