What is diecast scale? This is the first question most beginning diecast collectors encounter when they start to buy diecast cars.
Diecast scale is really just a measure of diecast car size. It may seem confusing at first, but it's really not so complicated.
The scale of a diecast vehicle is an indication of its size relative to the actual car that it is modeled after. This means that a 1/24 scale diecast toy car is one 24th the size of the actual car. A 1/18 scale car is one 18th the size of the actual car, and so on.
Note that diecast scale is expressed either as a fraction or as a ratio -- both have the same meaning. So 1/24 and 1:24 are exactly the same as far as vehicle scale is concerned.
Here's an example: if a real-life Corvette Stingray is about 15 feet (180 inches) long, then a 1/24 scale Corvette Stingray will be about 7 1/2 inches long (180 divided by twenty-four). A 1/18 scale replica of the same car would be 10 inches long (180 divided by 18). A 1/64 scale replica would be about 2.8 inches long.
In general, this means that for the same model car, a 1/18 scale version will be larger than a 1/24 scale version, which is larger than a 1/32, which is larger than a 1/43, which is larger than a 1/64, and so on. For those of you who still remember middle-school math, the number on the bottom of a fraction is called the "denominator" -- and the larger the denominator in the vehicle's scale, the smaller the car will be.
For reference, here is a chart of approximate sizes based on scale -- note that the actual size will vary based on the size of the original car that the diecast replica is modeled from:
|Diecast Scale||Approximate Size|
|1/18 Scale||9-12 inches / 24-30 cm|
|1/24 Scale||6.5-8 inches / 16-20 cm|
|1/32 Scale||4-6 inches / 10-15 cm|
|1/43 Scale||3.5-5 inches / 8-12 cm|
|1/64 Scale||2.5-3 inches / 6-7.5 cm|
Thus, a 1/18 scale diecast car is usually about 9-12 inches (depending on the size of the actual car). A 1/24 scale diecast car is generally about 6.5-8 inches. Many of the cars made in the smaller scales (1/32-1/38) are actually made so that the car will be exactly 5 inches long, regardless of the scale. The 1/64 scale cars are a similar size to "matchbox" cars, usually 2/5-3 inches.
Finally, it's important to note that larger vehicles, such as trucks or construction vehicles, are often made on a smaller scale (1/50 or 1/64), but are in fact about the size of 1/24 scale cars, since the actual vehicle is much larger.
