Radiant Size Chart documentation

Use these guides to move from installation to a published, product-specific sizing experience. The documentation follows the labels and behavior in the current Shopify app and storefront widget.

Start with the setup path#

1. Create or choose a size chart.
2. Assign it to the products or catalog rules that should use it.
3. Customize the storefront experience.
4. Enable the app embed or add the product page block in the theme editor.

Choose the guide that matches your task#

• New installation: follow Getting started from the app’s setup milestones to a live storefront check.
• Chart work: use Create and publish a size chart for lifecycle states, rows, units, and publication checks.
• Catalog coverage: use Assignments to understand products, collections, rules, and priority.
• Theme placement: compare the app embed and product block before changing your theme.
• Shopper guidance: review the Smart Selector journey and its conditional Shape step.
• Reporting: read Analytics before interpreting add-to-cart attribution or returned units.
