Model Scale, Part 2 – Standard Scales
Tuesday, August 24, 2010 Leave a comment
Although history of modeling industry is relatively short, we cannot possibly track a development of all standard scales and find an explanation for each particular scale. Because railroad models were the earliest products for modeling enthusiasts, there is no doubt that most of standard scales derived from these set for railroad models. The most popular scale in 1930-s England was O (or O gauge) which is 1:43, known today more as a standard scale for die-cast car replicas. Later, due to miniaturization of railroad models, US manufacturers developed a new scale by dividing the O-gauge in half – 1:87 scale or Legendary HO (see the connection in a letter code: half-O). HO scale today became the king of railroad scales that conquered the whole world. Approximately at the same time in UK another standard railroad scale was developed – OO gauge, the 1:76. OO trains were slightly larger than HO ones, however they were also compatible to the 16.5mm railroad track. For peculiar model maker a deviation between 1:87 and 1:76 scale is huge – 11 units. However for about two decades manufacturers tried to promote both scales as compatible, even were labeling their products as HO/OO. A birth of 1:72 scale is even more interesting. This scale, where 1 inch represents 6 foot was originated in UK in 1930, developed by companies producing aircraft replicas mostly for military recognition training. Some UK manufacturers starting 1960-s were producing plastic kits in 1:76 scale but labeling it as
1:72 scale. Later manufacturers switched to the true 1:72 scale. I the beginning of 1960-s Tamiya (Japan) came up with motorized plastic tank kits. 1:72 scale product would be too small to accommodate the electric motor, so Tamiya came up with 1:35 scale, which is awfully close to doubled 1:72. 1:35 scale became a hit and remain the most popular scale for military plastic kits till present. Throughout the history of standard scale’s development you can discover a connection between most of them when you will start dividing in half or doubling. Don’t forget, however, that the larger the sale, the lower the numeric value of it, and another way around.
It is nice when professional model maker has knowledge of scale predominates in terms of general education, but not a necessity. However, a model maker has to know by heart current standard scales and types of prefabricated models and accessories available. When it comes to architectural models, matching the scale of future architectural model to one of the standard ones is a must in order to use prefabricated scenery elements.
It is also important when model maker is commissioned to develop a scale model or replica for mass production, as each standard scale product has its own tradition and must-to-follow requirements.
Below is a table of some of the most popular standard scale for a number of industry’s fields and directions.
