How to Customize Size Chart Layout for Your Shopify Theme
Popup, tab, accordion, inline. Configure once or per-product.
The 4 Layouts
Popup (default). Click button → modal opens. Cleanest for short product pages.
Tab on product page. Inline below description. Surfaces sizing without click. Good for fashion brands.
Accordion. Collapsible "Size Guide" section. Compact + scannable.
Inline above 'Add to cart'. Always visible. Best for high-return categories (denim, lingerie).
Setup
App settings → Layout → choose default. To override per product, set metafield custom.sizing_layout on the product. Bulk edit via Shopify admin or CSV import.
