The main scale used for agricultural models is 1:16 scale. Construction is 1:50, but how big is that? This guide tries to help. We have many other popular scales on this site.
Scale definition
In it's simplest terms the scale of a model is the ratio of the size of the model to the size of the real item, meaning if you have a 1:32 scale tractor you will need 32 of them lined up nose to tail to equal the length of the real thing, so is 1/32 the size.
How big is a 1:32 scale model?
The exact size of the model will depend on the size of the real thing, though for an average size tractor a 1:32 scale model will be around around 12 cm / 5 ins in length, and an average 1:32 scale combine harvester will be around 30cm / 12 ins in length.

Note: The Ferguson show is half the size of the Fendt tractor above, as it is in real life!
