Two Measures of Scale. The size of a miniature, relative to what it is a replica of, is known as the scale of the figure. For no particularly good reason, two different systems are used to rate scale. Some scales are given as a ratio, variously written as either a ratio (i.e., 1:300 or 1.300) or a fraction (i.e., 1/300).
In addition to the major scales, slot cars have been commercially produced in 1:48 scale and 1:43 scale, corresponding to O gauge model trains. 1:48 cars were promoted briefly in the 1960s, and 1:43 slot car sets are generally marketed today (2007) as children's toys.
