The scale of a model refers to the chosen size when representing an object in a reduced form. There are various scales depending on the purpose of the model. A specific scale might be chosen for a model, for instance, to apply for a building permit or to monitor the production of a product.

Large and Small-Scale Models

Certain models require strict use of smaller scales. Examples include models of railways, cities, neighborhoods, and terrains. These objects are large and need to be represented in a simplified manner without going into excessive detail. Small scales encompass many objects and are more focused on showcasing the social context, geographic integration, and road planning of an area.

However, there are also models with larger scales, such as to illustrate floor plans or enhance an interior perspective. A larger scale is also used in prototyping to visualize a product during the design process, making it easier to identify errors through a larger representation.

Application of Scale to the Model

Thanks to laser cutting machines, parts or cut panels can be produced in relation to the chosen scale. Existing data is processed using software to create precise components for model construction. Similarly, 3D printers can be used to produce parts after volumetric data has been input. These parts are then assembled to create a finished model.

What Determines the Choice of Scale?

The choice of scale depends on common practices within a particular field of work and compatibility with digital and software-based processes. An example of this is the globally used HO scale in model railroading. This scale was established when the first model railway with a track gauge of 16.5 mm was introduced.
