Model Railway Forum

It is difficult to define but Brian has just given a good guide if we are referring to layout size. Up to 8x4ft is considered small. Over 8x4 up to 12x8 is considered medium. Large is anything over that.

Now what would be considered a small, a medium or a large collection if one is referring to numbers of trains etc?

(I hope I've put this in the appropriate section. It is railway related but is more general).

If a short psychic broke out of jail, then you'd have a small medium at large.

Sorry, couldn't resist

I would define a layout size on area rather than dimension, eg an 8 x 4 is considered small but if you had a 16 x 2 end to end that could be considered as large, yet they both have the same area 32 sq ft, so in this regard i would consider layouts up 40 sq ft as small, 40-100 sq ft as medium, and 100+ sq ft as large,

For the younger members, or the ones from metricated areas:

40 sq ft=3.716122m²

100 sq ft=9.290304m²

Round the metric values off as appropriate.
