So, judging from this article, about a 1/6th scale Millennium Falcon someone built:
This 1/6 Scale Millennium Falcon is One Huge, Fast Ship | Nerdist
Which was 18Ft long and 12 Ft wide, then a 1/12 scale would be 9Ft long and 6 Ft wide.
When you consider that the action figures are 1/18 scale, or just under 2/3 of 1/12 scale, that leaves a 4Ft wide, 6Ft long Millennium Falcon to match the action figures 0-8
Can't imagine how many pages it would take to print that! Not to mention needing to use corrugated paper just to hold it up.
