How it works

From chart to confident choice.

Four merchant steps turn the sizing information you already trust into a guided storefront experience.

For the merchant

A setup flow your catalog can grow with.

  1. Build the chart

    Choose a starting template or create a guide around the measurements and sizes your products actually use.

  2. Assign the catalog

    Connect guides to products and catalog rules, then use coverage signals to catch gaps before shoppers do.

  3. Match the storefront

    Select the launcher, panel, colors, typography, language, fit details, and brand treatment that suit your theme.

  4. Publish and learn

    Turn on the storefront embed and use consent-aware analytics to understand engagement, outcomes, and product-level gaps.

For the shopper

Four focused moments. One clear outcome.

Smart Selector asks only for the current details that help evaluate the assigned chart. Relevant shape questions appear only when the chart needs them.

  1. Details

    Basic profile details used for the current recommendation.

  2. Size

    Height and weight in the shopper's preferred units.

  3. Shape

    Only the body-shape selectors relevant to that garment.

  4. Result

    A recommended size, fit context, and an alternative when useful.

Before you publish

A small checklist with a large effect.

The strongest guidance starts with accurate chart ranges and a deliberate product assignment. Radiant helps organize the experience; your product data remains the source of truth.

  • Confirm chart units and product measurements
  • Review overlapping catalog rules
  • Preview the launcher and panel on mobile
  • Keep the full table and measurement guide available
  • Check consent-aware analytics after publishing
