Graphicscard PCB- dimensions

First of all I am sorry if I am posting this in a completly wrong board, but I couldn’t really find one wich fits my request.

My Name is Valentin and I am from the small modding company mercomods.

At the moment we are wokring on a configurator for fully customizable graphicscard backplates for our webshop (

For that to work I need to get every single Graphicscard plus the PCB-dimensions into this configurator.

I started researching and found out that there is a lot of false information in the Internet or for some older cards I was unable even find the PCB-dimensions size at all.

If you have any kind of list our valid source for you Graphicscards and their sizes I would be extreamly thankful if you could help me out with that.
