Diecast Model Scales Explained

The world of diecast models is vast. With thousands of replicas for the world's most iconic luxury, modern, vintage, sport, and heavy-duty vehicles, it can be challenging to know exactly which is the right scale to add to a collection.

What does "scale" mean in diecast?

Scale represents the ratio of the original vehicle to the diecast replica. Diecast model scales are usually expressed as a fraction or a ratio. The first or top number represents the model, and the second or bottom number represents the original by comparison.

For example, a car model scale represented as 1:32 or 1/32 means the diecast replica is 32 times smaller in length, width, and height than the original.

Why does car model scale matter?

In the diecast model world - size matters, but not necessarily for the reasons one might think.

For instance, a diecast replica that is 1:12 scale to the original will be approximately 33 cm in length. A diecast replica of that size may have trouble fitting on most shelves or display cases. Alternatively, a diecast replica that is 1:76 scale may be too small to fit on mounting posts or pegs.

Scale can also indicate the level of detail put into a diecast replica - the larger the scale, the more intricate the detail.

For example, many diecast replicas of classic Holden racing cars are made in scales ranging from 1:12 to 1:43 because the larger size allows diecast manufacturers to add intricate and visible decals, sponsors logos, and overall graphics.

So why even make small-scale replicas?

Smaller scales such as 1:64 and 1:76 shouldn't be considered less than their larger counterparts in any way. While there are many benefits to collecting larger-scale replicas, smaller scales are typically more affordable, have greater availability in most retail stores, and are easier to store in the home.

The smaller size also makes them ideal for building and displaying extensive collections in a home or office.

How many diecast model scales are there?

In the world of diecast model cars, there are more scales to choose from than you might think. Each has its own particular benefit and purpose, so keep the following in mind when thinking about which diecast replica you want to purchase for a collection.

1:12 Scale Models

Diecast models made in a 1:12 scale are used to replicate cars requiring extensive detail as well as figurines and motorcycles. Since people and motorcycles tend to be smaller than vehicles, this scale size is a great way to bring smaller originals to life with stunning detail.

1:18 Scale Models

The most common large scale size, 1:18, is for collectors looking for a statement piece that is detailed and massive, ranging between 24-30 cm in length. A 1:18 car model scale is often used for replicas of luxury sports and vintage cars.

1:24 Scale Models

While not as common in the world of diecast models one might come across at a store or website - 1:24 is still an impressive and detailed car model scale. These 1:24 models range between approximately 16-20 cm in length and are ideal for replicating racing, classic street and vintage Hollywood movie vehicles.

1:43 Scale Models

Often referred to as the "Collector's Size", 1:43 diecast model scales are the most common size found at stores and websites. Averaging approximately 11 cm in length, these scale models come in various styles, including passenger cars, commercial vehicles, commemorative series racers, and vintage classics.

1:50 Scale Models

When looking for diecast replicas of trucks, farming and construction vehicles, or trailers, you'll usually find them on a 1:50 scale. Since these vehicles tend to be quite large in real life, the 1:50 scale is perfect for reducing the size without sacrificing attention to detail on the interior and exterior features.

1:64 Scale Models

Typically referred to as the "Hot Wheels" or "Matchbox" scale, 1:64 replicas are among the smallest model car scales available on the market. Never larger than 7.5 cm in length, 1:64 scale diecast replicas are ideal for building extensive collections, displaying in areas with limited space, or as a gift to a child.

1:76 Scale Models

They really don't get any smaller than 1:76. This car model scale is usually reserved for oversized vehicles such as double-decker tour buses or giant city buses used as public transport. Besides their unique size, 1:76 models offer similar detail and availability to their slightly larger counterparts.

The Takeaway

Choosing the right diecast car model scale for your collection really comes down to personal preference and the particular replica you're looking for. One scale is no better or worse than the other as every diecast model is made with close attention to detail, regardless of the size.
