By the yard
Sell fabric by the yard on your Shopify store.
Shoppers enter how much they need, in yards or metres, and see the price straight away. Each fabric keeps its own price per yard.
A real Spark Kit calculator with a sample price. Type in your own numbers.
Yards do not fit a quantity box.
Shopify’s quantity selector counts whole items, so fabric stores end up with awkward workarounds: a "half yard" product, a quantity that secretly means quarter yards, or a note asking shoppers to do the math. A length field and a live price is what shoppers expect.
A length, not a count
Shoppers enter the length they want, in steps you choose, like quarter yards.
One calculator, every fabric
Set it once as the default for every product. Each fabric uses its own price per yard from Shopify.
The right price at checkout
Length times your price, shown live, and charged exactly at checkout.

Fabric by the yard calculator questions
Can I sell in metres instead of yards?
Yes. You choose the unit when you set up the calculator.
Can I set a minimum length?
Yes. Each field can have a minimum and a step, for example a half-yard minimum in quarter-yard steps.
Does the price match checkout?
The price always comes from your own product price in Shopify, so the total a shopper sees on the page is exactly what they pay at checkout. Change your price in Shopify and the calculator follows.
Will it work with my theme?
Yes, on any current Shopify theme that supports app blocks (every Online Store 2.0 theme, including Dawn). You add the calculator to your product page from the theme editor, with no code to paste in.
What does it cost?
Spark Kit is $14.99 per month with a free trial, and you can cancel any time. One subscription covers every calculator on your store.
