Diorama making and scale vehicle sizes can get a bit confusing that is why the Understanding Scale Replica Vehicle Sizes information was created to help clear it up a bit
There are so many different sizes available for the scale vehicle collector that it can be a little daunting. Scales are used to designate the size of scale replica vehicle. They reference the size of the vehicle compared to a life size car, truck, train, motorcycle, etc. For instance a 1:50 scale vehicle is one 50th the size of the real vehicle. The smaller the second number the closer to real life size, 1:1 scale. A 1:25 scale vehicle is twice as big as a 1:50 scale vehicle of the same item.
I created a little something I call Understanding Scale Replica Vehicle Sizes to help clear it up a little, there is a general guideline for railroad vs. scale replica vehicles. Scale sizes and general comparisons such as;
A vehicle that is 50′ long in real life will be 1′ long if reproduced in 1:50th scale.
A vehicle that is 16′ long in real life will be 1′ long in 1:16th scale.
A vehicle that is 1:24th scale means it is 1:24th the size of the actual vehicle in real life.
