Shopify "Smart Size Matcher" with “Pin code Delivery Estimator” Project Overview I need a custom-built UI for my Shopify Standard product pages to help customers find the correct Standard Size mosquito net. The tool needs to handle size matching logic and provide a delivery estimate based on the user's Pin code. The User Flow: 1. Visual Guide: A small "How to Measure" snippet (Infographic) showing the Inner Frame (Clear Opening) in cm. 2. Product Selection: User selects Colour and Design (standard Shopify swatches). 3. The Inputs: Size: User enters Width (cm) and Height (cm). Location: User enters their 6-digit Pin code. 4. The Checkbox: A mandatory "I have measured the Inner Frame correctly" checkbox. The Technical Logic: Next-Size-Up Matching: The system adds a pre-set [X] cm overlap to the user's input and automatically matches them to the smallest Standard SKU that is still larger than their requirement. Delivery Estimate: Based on the Pin code entered, the tool should display "Estimated Delivery: [Date] or [X] Days." Note: This can be pulled via API (Shiprocket/ Delhivery) or a static "Zone-based" table. Custom Redirect: If the size exceeds our largest Standard SKU. “Need an exact fit or a larger size?
