Custum product calculator

Shopify Apps

Topic summary

Goal: Enable customers configuring a skylight (width, depth, number of glass panes, profile color) to automatically populate the cart with the correct pre-existing products/variants (e.g., specific glass sizes and profile types/lengths), without the customer doing research and without complex new calculations.

Suggested approaches:

  • Explore product personalization (variants) or product calculator apps from the Shopify App Store. Note: many such apps create their own products or come with constraints.
  • Implement theme customizations if all required products already exist; map user inputs to specific products/variants and quantities, avoiding dynamic product creation or custom pricing.

Example given: A custom length input (e.g., 1344 mm) could automatically select the nearest matching variant (e.g., 1500 mm) using rounding logic.

Resources: App Store searches for “personalization” and “product calculator” were provided. A custom build (theme or app) was offered as a service.

Status: No single app recommendation or final decision. Next steps are to research apps or proceed with a theme-based mapping solution; discussion remains open.

Hello everyone,

I am in the preparations for building a shopify webshop.
We are selling building materials that can be used for skylights.
Now I would like to have an option that customers could fill in a couple of options. By filling in these options I would like to see that Shopify automaticly selects the different kind of products with the right measerments. So the customer doesn’t have to do any research in what he needs to have.

For example. My custumor would like to build a skylight by himself, but he doesn’t know which materials he needs.
If we have the following options he can fill in:
Width: 300
Depth: 150
Number of glasses: 3
Color profiles: *Black
*
The following products then most show up in the chart:

**Temperred glas 55.2: **
3 pcs
Width: 980
Length: 1500 MM
**Profile A: **
2 pcs
Length: 1500 mm
Color: Black
Profile B:
2 pcs
Length: 1500 mm
Color: Black
Profile C:
1 pcs
Length: 3000 mm
Color: Black

So I am wondering I there’s any Shopify app that can do this. It’s not about the calculations, but just about an app that can pick the right products by filling in some options.

Thanks for your reply

Your tangentially looking for product personalization(aka product variants ) or calculation apps.
But most do create their own products or need other considerations
There’s always just doing the research:
https://apps.shopify.com/search?q=personalization
https://apps.shopify.com/search?q=product%20calculator

Or simpler this can be done with theme customizations when the products are pre-existing and all thta’s need really is just to map values to products;
an not other unspokens like having to dynamically create new products or custom prices, etc etc etc.
You can reach out to me for services to build this as a theme approach , or custom app if you can’t find an off-the-shelf that fits.

An example is a custom to length input where choosing 1344mm automatically choose the 1500mm variant or some other rounding logic.
