Supra Size Chart

Manage all your size charts in one app without editing theme code or product descriptions. Create professional size guides using a visual editor with rows, columns, per-column units, and instant inch/cm conversion. Add a labeled measurement guide showing shoppers exactly where to measure — chest, waist, hip, and more. Assign size charts using clean rules based on product, collection, product type, vendor, or tag. Deploy once and forget about manual updates. Choose how charts display on your product pages: inline table, accordion, or modal. The theme app block renders everything server-side with no coding required. Import size charts from CSV and export anytime as CSV or JSON — no lock-in. One size-chart system for your entire catalog that actually works.
