Setting up your first size chart is straightforward.

Add your specific measurements and images, then assign the chart to relevant products, collections, or vendors. The app provides intuitive table editors and allows for quick 5-minute setup.

If your size chart isn't displaying, first ensure theme app extensions are enabled in your theme settings. Check that the size chart is properly assigned to your specific product, collection, or vendor. Verify the chart is published and not in draft status. For persistent issues, the support team offers personalized assistance to troubleshoot display problems and ensure proper integration with your theme.

You can easily customize the size chart link text through the app settings. Navigate to the Clean Size Charts configuration section and locate the 'Link Text' option. This allows you to change default text like 'Size Chart' to match your brand's terminology, such as 'Sizing Guide' or 'Fit Guide', providing a more cohesive shopping experience for your customers.
