As far as heft goes wrap you head around this. 0 scale has 8 times the presence of HO.
act.
Actually, it's closer to 1.81 times the size of HO,
Heft/ Volume and Size. I’d call it a draw and say your both correct.

In fact, it is said that historically, the name "HO" was inspired by it being "Half O". Even though every linear measurement in O scale is about twice the same measurement in HO scale, remember that each measurement in a 3-D item in O scale is twice that in HO scale. (i.e. length, width, height) So, for example, the volume of a structure in O scale is actually eight (8) times that of the same structure in HO scale. That is an important factor to remember when considering space requirements for each scale.
