How to Add a Size Guide in Shopify Symmetry Theme

Symmetry has a native size guide feature — a real fit-and-measurement block that matters a lot for a theme built around fashion, health, and beauty products.

Steps

1. In your Shopify admin, go to Online Store > Themes and click Customize on Symmetry.
2. Open a product page and select the Product information section.
3. Click Add block and choose Size guide.
4. Build the chart's rows and columns for your size range, or link to a shared size guide page if your catalog uses the same chart across many products.
5. Set which products or product types the guide should appear on.
6. Click Save.

Keep the guide in the same units your customers actually shop in — for a store selling internationally, showing both metric and imperial measurements cuts down on sizing-related support requests and returns.
