There are many other scales for the models, particularly earthmoving equipment and trucks which are typically 1/50 scale, and as the real machines of such models are quite large, a 1/50 scale model of such machines could be in the range of 20 to 40 cm long.

For example, the scale of 1:50 means that 1 mm on the drawing represents 50 mm on the object. This means that the object is 50 times larger than the drawing of it. An object 450 mm long would be represented by a line 9 mm long (450 mm/50).

1:43 scale is a popular size of die-cast model cars in Europe, Asia and the US. It has its origins in the British / European O scale for model trains and the rise of certain accessories made for that scale which since have become popular in their own right. Models in this scale are 10–13 cm length (3.93–5.11 inches).
