I need a small, well-structured block of Liquid and vanilla JavaScript added to the Dawn product page that lets shoppers type their room length and width (in metres), press nothing else, and immediately see: • total square metres required, driven by an accurate, rock-solid m² formula (this calculation is the heart of the job) • an optional 10 % wastage toggle presented as a smooth on/off switch • the number of full packs they must buy, rounded up automatically because packs are sold in set sizes, with no extra choice or dropdown required • the live product price adjusting as pack quantity changes, and that exact pack quantity flowing straight into the cart Everything needs to look native inside the current Dawn layout, work flawlessly on mobile, and survive future theme updates. I’m only after clean, commented code—no third-party apps or bloated libraries. Deliverables – Liquid, CSS and JS snippets ready to paste into Dawn – Clear installation notes (file names, line numbers, and how to reverse) – Quick screen-capture or demo link proving mobile behaviour Timeframe is three days and I’m offering a single fixed-price arrangement (no hourly quotes). When you reply, please include at least one Shopify project where you built comparable custom functionality without relying on apps; it will help me choose fast.

⭐⭐⭐Shopify Dawn m² Calculator + Auto Pack Pricing⭐⭐⭐ Flooring stores run into this exact problem — customers know their room size, not how many packs to buy. The cleanest fix is a small native calculator tied directly to the product form so pack quantity updates automatically. ✅ Accurate m² calculation (length × width) with instant output while typing ✅ Smooth 10% wastage toggle that recalculates pack quantity live ✅ Automatic pack rounding based on pack coverage (no dropdowns) ✅ Quantity synced to the product form + cart so price updates instantly ✅ Implemented with Liquid + vanilla JS only, styled to match Dawn and safe through theme updates I recently built a similar tile coverage calculator in Shopify where pack quantities updated the cart automatically without any apps. Your deliverables will include the snippet files, install steps (exact file + line placement), rollback instructions, and a mobile demo recording. Quick detail: how many m² does one pack cover for this product? That value drives the rounding logic.

Hi! You need a Dawn native area calculator that takes length and width in metres, instantly computes m2, optionally adds 10 percent wastage, converts that to packs by rounding up based on pack coverage, updates the displayed price live, and pushes that pack quantity straight into cart. I’ll implement it as a small Liquid snippet plus vanilla JS that hooks into Dawn’s quantity and price sections so it survives theme updates. I’m Edward, 10+ years dev. Similar work: custom Shopify product page calculator that set variant quantity and updated price without apps. Happy to chat more about this.

I've built exactly this kind of thing on Dawn before - custom m2 calculators with pack rounding and live price updates, all vanilla JS + Liquid, no apps. Your spec is pretty clear so this should be straightforward. I'll set up the length/width inputs, the wastage toggle with a clean CSS switch, and wire up the pack quantity logic to flow directly into the cart. Everything commented and reversible. Happy to share a previous Shopify customization where I did similar product-page JS work. Can have this done well within your 3 day timeline. - Usama

Hello, I’ve read through your goal of adding a native-feeling flooring area calculator directly into the Dawn product page, and the emphasis on a rock‑solid m² formula and pack rounding stands out clearly. I previously built a custom area‑to‑pack calculator for a tiles brand, delivering instant m² outputs and dynamic pricing without any apps, and another Dawn‑based project where I injected update‑safe Liquid/JS modules that survived multiple theme upgrades. The real challenge here is ensuring the calculator hooks into Dawn’s dynamic cart and variant logic without breaking theme scripts or being overwritten during updates. The pack‑rounding and live price recalculation also need to run cleanly inside Shopify’s event model to avoid double‑binding issues. I’ll create isolated Liquid and JS snippets, bind calculations only to size inputs, and update pack counts using Shopify’s native cart form. The wastage toggle will use a lightweight switch built in pure CSS/JS to keep everything dependency‑free. Before finalising, I want to confirm the current pack‑size structure and whether it varies by variant or product. I can deliver in three days with installation notes and a mobile demo. Thanks, John allen.

It’s frustrating when something as essential as a flooring calculator just doesn’t feel right in Shopify. Relying on clunky apps or bloated code only slows your store down and risks breaking with every Dawn update. You need a native, seamless solution that gives shoppers instant m² results, an easy wastage toggle, and automatic pack rounding, all styled to fit perfectly on every device. With clean, well-structured Liquid and JavaScript, you’ll have a calculator that updates live with every keystroke and sends the right pack quantity straight to the cart. You’ll see it working smoothly on mobile, with every calculation accurate and every element blending naturally into your product page. I’ll create and comment the code, give you clear install and removal steps, and share a quick demo showing it in action. Could you share the pack size in metres so I can make sure rounding is spot on?

Hi, I understand that you need a lightweight, native solution added to your Shopify Dawn product page to calculate flooring requirements. My approach would be to create a clean Liquid block for the product page and use vanilla JavaScript to capture room length and width, calculate total square metres, optionally add 10% wastage via a smooth toggle, and round up to the number of full packs automatically. The script will dynamically update the product price based on the calculated packs and push the correct quantity into the cart. All code will be fully commented, responsive for mobile, and designed to integrate seamlessly with the Dawn theme without affecting future updates. Before delivery, I will test all calculations, toggle functionality, price updates, and cart integration across desktop and mobile devices to ensure reliability. Installation notes will clearly explain file placement, line numbers, and rollback instructions. Best, Justin
