Card Sorting

Ever wondered why some websites feel easy to browse through while others leave you clicking around in frustration? The secret lies in how their information is organized within the website. Card sorting is a straightforward technique that helps you figure out how users naturally group and categorize content.

It’s a lifesaver for crafting intuitive website navigation, designing seamless apps, and building solid information architecture. Around 69.99% of online shopping carts are abandoned, often due to poor navigation and design.

Don’t let your site fall into this category. Let’s explore how card sorting can enhance your user’s experience.

let’s make trust the foundation of every project you work on.

Why Card Sorting Matters for User Experience

Let’s be real, no one likes fumbling around a website trying to find what they need. A seamless user experience starts with organizing information in a way that makes sense to your audience. That’s exactly what card sorting helps you do. It’s not just about structure; it’s about creating an experience that feels natural, intuitive, and frustration-free.

Here’s why card sorting should be in every designer’s toolkit:

  • Simplifies Information Organization – Ever landed on an app and thought, “Where do I even start?” Card sorting eliminates that confusion by organizing content logically so users can easily find what they’re looking for. Take Amazon for example, categories like “Electronics,” “Clothing,” and “Home Essentials” make browsing straightforward. Without this structure, shopping would feel like wandering aimlessly through a giant warehouse.
  • Improves Website Navigation – Good navigation can make or break your website. If users can’t figure out where to go, they’ll leave or abandon mid-way. Card sorting helps you design menus and paths that guide users effortlessly.Look at Spotify. Their navigation is clean, with options like “Playlists,” “Podcasts,” and “Genres” front and center. This intuitive setup reduces frustration and keeps users coming back for more.
  • Aligns with User Mental Models – Here’s a secret: how users expect information to be grouped might be completely different from what you think. Card sorting ensures your structure aligns with their mental models, creating a smoother experience.
  • Improves Content Discovery – Card sorting isn’t just about organization, it’s about making sure users find the content they didn’t even know they were looking for.Netflix has successfully cracked this code. With categories like “Top Picks for You” and “Trending Now,” they make it super easy to stumble upon your next binge-worthy show.
  • Optimizes Information Architecture – Think of card sorting as laying the foundation for your site’s structure. A well-organized architecture leads to better usability and happier users.
  • Enhances User-Centered Design – The best part about card sorting? It’s driven by real user input. Instead of guessing how to organize your content, you’re letting your users show you exactly how they think.Platforms like Google Drive categories like “Shared with Me” and “Recent” reflect how users actually search for files, making the platform intuitive and user-friendly.


Card sorting is more than just a research method, it’s the key to creating websites and apps that users love. It ensures intuitive navigation, improves content discovery, and puts your users’ needs front and center. If you want to keep your audience engaged and happy, card sorting is the way to go!

Types of Card Sorting: Open, Closed & Hybrid

Types of Card Sorting Open, Closed & Hybrid

When it comes to card sorting, there’s no one-size-fits-all approach. Depending on your goals and where you are in the design process, you can choose from open, closed, or hybrid card sorting. Each type offers unique benefits to help you understand how users think and organize information. Let’s break them down.

Open Card Sorting

Participants group items (like page titles or product names) however they like.They also create their own labels for each group, giving you fresh, user-driven insights.

This method works best in the early stages of design, when you’re exploring how users naturally categorize content.

Think of it as a blank canvas that reveals unexpected ways users think about your information.

Why it’s valuable: It gives you an unfiltered view of user preferences, helping you build a structure that aligns with their mental models.

Closed Card Sorting

In this method, participants sort items into pre-defined categories you provide.It’s ideal for testing and validating a structure you’ve already created.

For example, if you’re designing a retail website, you might test categories like “Men’s Clothing” or “Accessories” to ensure they make sense to users.

Why it’s valuable: Closed card sorting ensures your categories are clear and logical, reducing confusion and improving navigation.

Hybrid Card Sorting

A combination of open and closed methods, this approach lets participants use pre-defined categories but also allows them to create new ones if needed. It strikes a balance between structure and flexibility, making it a versatile option for testing.

Use this when you want feedback on structured categories while leaving room for users to suggest improvements.

Why it’s valuable: Hybrid card sorting combines the best of both worlds, capturing fresh insights while validating your existing structure.

Open card sorting is great for uncovering new ideas, closed card sorting helps validate your structure, and hybrid offers flexibility with structure. No matter which you choose, card sorting ensures your design is built with users at the center.

Best Practices for Effective Card Sorting

Want to get the most out of your card sorting tool & sessions? Follow these best practices to ensure your results are meaningful and actionable.

1. Set Clear Objectives

Be clear about what you’re testing. For example, if you’re designing a retail site, decide if you’re testing product categories or navigation. Knowing your focus keeps the process efficient.

2. Use Plain, Understandable Language

Avoid jargon or internal terminology. Instead of “SKUs,” use “Products” so participants can relate. Clear labels lead to better insights.

3. Limit the Number of Cards

Stick to 30–40 cards. For instance, if you’re organizing an online grocery store, focus on core categories like “Fruits,” “Vegetables,” and “Dairy” instead of listing every item.

4. Recruit the Right Participants

Test with people who resemble your target audience. If you’re designing for students, test with students. Their perspective will shape your structure effectively.

5. Choose the Right Card Sorting Type

Choose the right card sorting method based on your project goals. Open sorting is perfect for exploring how users naturally group items during the early design phase. Closed sorting works well when you need to validate existing categories. For a mix of creativity and structure, hybrid sorting is the way to go.

For example, if you’re organizing an e-commerce site, hybrid sorting can reveal if users group “Sneakers” under “Shoes” or create a new category like “Sportswear.”

6. Analyze and Iterate

After the test, look for patterns. If 80% of participants grouped “T-shirts” and “Sweaters” under “Clothing,” you’re on the right track. Refine and retest if needed.

Effective card sorting starts with clarity and ends with iteration. Follow these tips, and you’ll build an intuitive structure that works for your users.
