I understand Shopifys very limited pricing logic and that all apps must fall into that logic. So i’ll try to present what I am trying to do conforming to Shopifys system.
I currently use Globo Product Options for all my variations and it works good. But I have a printed item that can be ordered at custom arbitrary sizes. I know Shopify cant handle custom dimensions so I created square footage groups (variations) that if the size falls into the groups it chooses the correct price. But what app exists that can calculate the two dimensions that the customer chooses and select the proper variation in the back end.
Essentially if a customer chooses 24” on a dropdown menu, and 36” on the other dropdown, the app can understand go choose the “6 Square Feet” variation and apply it at checkout.
Yes I know Shopify is not made for this. But there has to be some app that can handle this. Or even an app that creates a new custom product every time a customer makes selections.
You can get inside the theme and manipulate the code to suit your need.
You could ask Sidekick to give you a script that does the math and basically do whatever you want it to do. Then you place the script in the main-product.liquid file or product-form.liquid file, or in a custom liquid section in the theme editor.
Shopify is made for exactly this. You have a need for custom sizes and prices. Shopify gives you control over the theme files, and even provides a AI tool that can give you the code.
If your goal is for customers to enter custom dimensions and have the system automatically calculate the corresponding price, Easify Product Options can be set up to handle this quite intuitively.
Here’s an example I’ve created so you can see how it works:
In the app, you just need to create a new option and select the Dimension type. Then you can set up two fields: Width and Length, choose the measurement unit (for example, inches), and define the min/max limits for each dimension based on your needs. Once configured, customers will see two input fields on the product page where they can enter their desired dimensions.
After that, go to the Advanced settings of this option and enable Add price to set up the pricing formula. For example, you can use a formula like x * y * {{price}}, where x and y represent the Width and Length values entered by the customer, and {{price}} is the unit price per area. When customers change the dimensions, the system will automatically recalculate the total price and display it instantly on the product page before they add the item to the cart.
This setup allows you to avoid creating multiple size variants in Shopify. Instead, you only need a single base product. Customers can enter their desired dimensions, and the app will automatically calculate the price based on the Width and Length values they provide. This approach is especially suitable for products that require custom sizing, such as rugs, printed artwork, signage, or materials that are cut to order.
I hope you are doing well. You can try the Inkybay – Product Personalizer app for dynamic pricing according to the custom free size option.
With Inkybay’s Product Option feature, you can create a preset size and a custom free size option so that customer can put their custom size. You can set pricing for the preset and custom size options. Also, you can set the inch/cm/ft measurement option for your product. All customer selections will show properly on the cart page and will be automatically saved with the order, so you receive everything clearly in the order file.
Inkybay also lets you add other advanced options such as text fields, file upload options, and image swatches.
The best part is that no coding is required, and a simple setup. It offers a free 21-day trial so you can explore it and see how it works for your product.
