In 2026, both Fit Quiz: Size recommendation and Jotly Size Charts & Size Guide address the critical issue of sizing accuracy for Shopify merchants, aiming to reduce returns and boost sales. However, they take distinct approaches. Fit Quiz positions itself as a modern alternative to traditional size charts, offering a dynamic quiz that provides personalized size recommendations without requiring sensitive customer data like body measurements. Jotly, on the other hand, focuses on enhancing and customizing traditional size charts and guides, providing a comprehensive solution for displaying detailed sizing information in a visually appealing and brand-consistent manner. Fit Quiz is focused on clothing and footwear, while Jotly appears to be more general purpose, although both support multi-language. Fit Quiz's strength lies in its ease of use and its focus on automation. It bypasses the need for manual size chart creation and offers automatic recommendations for returning customers. Its target audience appears to be clothing and footwear brands seeking a quick and effortless solution for sizing. Jotly's strength is its flexibility and customization options. It is designed for merchants who want complete control over the presentation of their sizing information and who need to support a wide range of products. The difference is really between automated size recommendation and enhanced size charts.

For clothing and footwear brands seeking a hands-off, data-driven approach to size recommendations, Fit Quiz: Size recommendation is the better choice. Its quiz-based system requires no size charts and offers a personalized shopping experience. It's great for merchants who want to quickly reduce returns without significant setup effort.
Jotly Size Charts & Size Guide is better suited for merchants who prioritize complete control over their size charts and need a highly customizable solution for a broader range of products. It is perfect for brands seeking to maintain a consistent visual identity and provide detailed sizing information to their customers. While requiring more setup and data entry, Jotly delivers the flexibility needed to create a tailored sizing experience.
Fit Quiz does not collect sensitive data like weight, body measurements, or body scans. It gathers information through the quiz to provide personalized size recommendations.
Jotly Size Charts & Size Guide can be used for any product type including apparel. The app’s flexibility allows you to create size charts and guides tailored to specific products, collections, or tags.
Fit Quiz is designed for easy setup, requiring no size charts or garment measurements. Jotly is more customizable, but setup is more involved due to manual data entry and layout configuration.
Jotly enables more detailed sizing information by enabling you to include tabs, images and tables directly in the size chart. Fit Quiz focuses on providing simple size recommendations, plus potentially width/length/fit recommendations, but not full size chart data.
Both apps offer multi-language support, allowing merchants to cater to a global audience by translating their size guides and recommendations.
