Made to measure
Price banners and signs by size on your Shopify store.
Shoppers enter the width and height and pick their finishing. The price per square foot, your setup fee, and the extras add up live.
A real Spark Kit calculator with a sample price. Type in your own numbers.
Print buyers want a price before they upload artwork.
A banner shopper is comparing you with two other printers in other tabs. If your page says "contact us for a quote" and theirs shows a price, they have already gone. A live price for their exact size keeps them on your page and moves them to checkout.
Priced per square foot

Setup fees and finishing

Banners and signs calculator questions
Can I add a setup or artwork fee?
Yes. A setup fee is part of the formula, so it shows in the price the shopper sees.
Can finishing options change the price?
Yes. Checkboxes and dropdowns can each add to the price, like hemmed edges or grommets in the example on this page.
Does the custom price carry through to checkout?
Yes, on every Shopify plan. The shopper checks out at exactly the price they saw.
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.
