Video game box size comparison?

[Palgrave]

Hello, I have been hunting for images comparing various game boxes for each system but haven't had much luck. The reason I ask is because I am making 3d models and so far have been guesstimating based from memory and would like to get them to be more accurate. I dont have any of the boxes and in some cases never even owned the box (like turbografix games) as I got the games from friends.

So far I have made ones for NES, SNES and Genesis shown below

If anyone can point me to any comparison images that would be fantastic!
