A template for your trade
Start from a ready-made calculator: flooring, tile, wallpaper, paint, bulk material, pool and spa, banner and vinyl. Pick the closest one and tweak it to your products.
Built for Shopify
Sell by the square foot, the roll, or the yard, right on your product page.
Shoppers enter their measurements, see exactly how much they need and what it costs, and add it to cart with confidence. No more guesswork, no more “how many boxes?” emails.

A real Spark Kit calculator on a sample product page. Type in your own numbers and watch it work.
Why Spark Kit
Shopify sells in fixed sizes. Your customers don’t measure that way.
A room is 14 by 11 feet, not “6 boxes.” Spark Kit does the math on your product page, so shoppers buy the right amount the first time, and you stop fielding wrong orders and returns.
Set it up yourself, no code
Edit your inputs, pricing, and labels in one simple editor with a live preview. No developer, no theme code, no support ticket. Change it anytime.
Sell by the box or cut to size
Round a room up to whole boxes and rolls, or price made-to-measure items cut exactly to a shopper’s dimensions. The total they see is the total checkout charges.Made-to-measure pricing requires Shopify Plus.
Matches your brand, safely
It picks up your store’s colors and sits right on the product page, and it can never break your theme. If anything is ever off, it quietly hides instead of showing an error.
