Hi..I want to add variants to my shopify product “blind curtain” that customize price based on unit and dimensions
I have one product and need to do this customization

My product link is

I wanna add same variants exactly as the below product

https://guardblinds.com/products/guard-total-blackout-blinds?variant=49597376627029

I got a good app in shopify “option calculator” that can do the job.
The below image shows the unit, width,height that are variant and the price will be based on these variants

Please also note that there are 2 units, cm and inches

Please check the link and change dimensions, so you will see the price is changed accordingly

My budget is 25$ and timeline is 2 days delivery

I got a good app in shopify “option calculator” that can do the job. So I want experienced one to set it up correctly for me
It may or may not need some coding im not sure


Thank you
