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.

At this scale, 1⁄4 inch represents 1 foot. It is similar in size to 1:50 scale and 1:43 scale, which are popular for diecast vehicles. In 2003, Tamiya began to manufacture a line of military ground vehicle models in 1:48 in addition to their more traditional 1:35 scale line.

The 1:64 scale is a traditional scale for models and miniatures, in which one unit (such as an inch or a centimeter) on the model represents 64 units on the actual object. It is also known as the "three-sixteenths scale" since 3/16 of an inch represents one foot.

Each model is a meticulous, downsized version of a vehicle or train, where 1 unit of measurement on the model equates to 76 of the same units on the full-sized version. For example, if an actual train car is 76 feet long, a 1:76 scale model of that train car would be 1 foot long.
