Scale (ratio)

The scale ratio of a model represents the proportional ratio of a linear dimension of the model to the same feature of the original.

Description

Examples include a 3-dimensional scale model of a building or the scale drawings of the elevations or plans of a building.

In such cases the scale is dimensionless and exact throughout the model or drawing.

The scale can be expressed in four ways: in words (a lexical scale), as a ratio, as a fraction and as a graphical (bar) scale. Thus on an architect's drawing one might read

'one centimetre to one metre' or 1:100 or 1/100 and a bar scale would also normally appear on the drawing.
