SCALE is the size relationship of a model to the real world. Usually, it is expressed in fractions. Thus, a scale of 1/43 has dimensions that are a forty-three the height, length, width and depth of its real-world counterpart. Another way of doing this is 1:43, or "one to forty-three". That means that one inch or millimeter of real measure equals forty-three of the miniature.


Nowadays most diecast models are generally offered in the scale of 1/12, 1/18, 1/24, 1/32, 1/35, 1/43, 1/48, 1/50, 1/64, 1/72 and 1/87. Nevertheless, larger scale such as 1/2, 1/6, 1/8 and 1/10 are available in the market but not common. And the smaller scale like 1/90, 1/100, 1/144, and 1/2500 etc. are usually crafted for larger vehicles - aircraft and ships. The scale of 1/38, 1/40 or 1/55 etc in between are not the main stream in the industry and seldom made by the major brands.


However, the size of the models fall in the same scale may slightly variant from brand to brand. For instance, Autoart’s model will a bit larger in size than Minichamps’ models; and Collector’s Model (CsM) is obviously smaller than that of the Corgi. Hence, we cannot define which brand or company is representing the true scale indeed while most collectors may not concern anyway.
