Manage every size guide in one app instead of editing theme code or product descriptions. Create charts in a visual editor (rows, columns, per-column units with instant in/cm conversion, notes) and add a labelled measurement guide so shoppers know where to measure. Assign charts with clean rules (product, collection, product type, vendor, tag), and choose how they display: inline table, accordion, or modal. A theme app block renders them on your product pages, no coding required.

• Show a visual guide of where to measure — chest, waist, hip, and more
• Build reusable charts in a visual editor with per-column units + in/cm convert
• Assign by product, collection, type, vendor, or tag — deploy once, forget
• Display inline, as an accordion, or in a modal — rendered server-side
• Import from CSV, export anytime as CSV or JSON — no lock-in
