Cart-aware area calculator for products sold by the box. Pattern, waste factor, min-buy logic.
Customers enter their room dimensions. The calculator applies the appropriate waste factor (5% for straight lay, 15% for diagonal, 20% for herringbone), rounds up to the nearest box, enforces the minimum-buy, and adds the correct quantity to the cart.
5 stages from first touch to closed loop. The system runs this path autonomously; the operator only sees the result at the end.
he default Shopify quantity picker is useless for flooring. A customer with a 340 sq ft room who doesn't know the box coverage or waste factor will either under-order (returns are expensive for freight-heavy products) or call sales. The Sq Ft Calculator eliminates that call and prevents under-ordering.
The stack is on the bench, the wiring is documented, and the instance you ship with is yours to extend after handover.
Client-side Hydrogen component with product metafield integration (box coverage, waste presets, min-buy per pattern). Cart mutation via Storefront API. No backend required — all logic runs in the browser with product data fetched at build time.
