Model Car Scale Guide: Sizes in cm and Inches from 1:8 to 1:64

In short

A model car scale tells you how many times smaller the replica is than the real car: divide the real length by the scale number. A typical 4.5-metre car measures about 56 cm in 1:8, 37.5 cm in 1:12, 25 cm in 1:18, 19 cm in 1:24, 14 cm in 1:32, 10.5 cm in 1:43 and 7 cm in 1:64. In the Vroomi catalogue, 1:43 and 1:18 are by far the largest ranges, followed by 1:12; 1:8, 1:24, 1:32 and 1:64 cover more specialised subjects, and racing helmets come in 1:2 and 1:5.

Choosing a scale decides almost everything else in a collection: how much shelf space you need, how much detail you can see, and how many cars can tell one story side by side. This guide gives you the real size of each scale in centimetres and inches, explains where the most common ratios come from, and shows the same race car — the Ferrari 499P that won Le Mans in 2024 — in three different scales, with the length each one reaches on the shelf.

How model car scale works

A scale is a ratio. At 1:18, every centimetre of the model represents 18 centimetres of the real car; at 1:43, it represents 43. The bigger the second number, the smaller the model. To find the length of any model, divide the real car's length by the scale number: a 4.5-metre saloon in 1:43 is 450 ÷ 43 ≈ 10.5 cm.

Two practical notes. First, 1:18 and 1/18 mean exactly the same thing; manufacturers simply use different notation. Second, length depends on the subject: a compact hatchback, a modern hypercar and a 1950s American sedan in the same scale can differ by several centimetres. A Le Mans Hypercar, which the regulations allow up to 5 metres long, measures up to about 28 cm in 1:18 and 11.6 cm in 1:43.

Model car scale size chart in cm and inches

Scale	4-metre car	4.5-metre car	5-metre car
1:8	50 cm (19.7 in)	56.3 cm (22.1 in)	62.5 cm (24.6 in)
1:12	33.3 cm (13.1 in)	37.5 cm (14.8 in)	41.7 cm (16.4 in)
1:18	22.2 cm (8.7 in)	25 cm (9.8 in)	27.8 cm (10.9 in)
1:24	16.7 cm (6.6 in)	18.8 cm (7.4 in)	20.8 cm (8.2 in)
1:32	12.5 cm (4.9 in)	14.1 cm (5.5 in)	15.6 cm (6.2 in)
1:43	9.3 cm (3.7 in)	10.5 cm (4.1 in)	11.6 cm (4.6 in)
1:64	6.3 cm (2.5 in)	7 cm (2.8 in)	7.8 cm (3.1 in)
1:87	4.6 cm (1.8 in)	5.2 cm (2 in)	5.7 cm (2.3 in)

The figures are pure maths, so they apply to any maker. Real models can differ by a few millimetres, because some manufacturers round the scale or adjust proportions slightly.

One car, three scales: the Ferrari 499P No. 50

The clearest way to understand scale is to look at one subject in several sizes. Looksmart produces the Ferrari AF Corse No. 50 of Antonio Fuoco, Miguel Molina and Nicklas Nielsen, overall winner of the 2024 24 Hours of Le Mans, in 1:43, 1:18 and 1:12. The livery and the shape are the same; what changes is how much of the car you can actually read — from the overall silhouette in 1:43 to cockpit, sponsor print and aero details in 1:12.

For collectors: if you want the car itself to be the story, choose the Looksmart 1:12 or the Looksmart 1:18. If you want the whole race, the Looksmart 1:43 lets you line up the winner with its rivals on a single shelf. For a die-cast alternative in 1:18, Burago makes the same No. 50 with a display case.

1:8 scale: the showpiece

At 1:8, a sports car is more than half a metre long. These are rare, heavy pieces built in very small numbers, designed to be the single object that defines a room rather than part of a row.

For collectors: the GT Spirit Porsche 911 Turbo (930) in 1:8 shows what this format is about — bodywork you can study like a real car. Plan a dedicated plinth or a deep shelf.

1:12 scale: the centrepiece

1:12 is the largest scale that still fits a normal shelf or sideboard. Expect around 33–42 cm for most cars. It is used for halo subjects: Le Mans winners, Formula 1 cars and iconic road cars, often in resin and in limited numbers.

For collectors: one or two 1:12 models give a display a clear focal point. Browse the 1:12 scale model cars collection to see the current subjects.

1:18 scale: the collector standard for detail

1:18 is the reference scale for detailed road and racing cars, at roughly 22–28 cm. Its success is relatively recent: the first zinc-alloy 1:18 cars from European makers such as Schuco, Polistil and Gama appeared around 1970, and the scale grew steadily from the mid-1980s with the Italian brands Bburago and Polistil, followed by Maisto. Today it covers both die-cast models, often with opening doors and engine covers, and sealed resin models focused on exact shape and livery.

For collectors: a 60–80 cm shelf holds two or three 1:18 cars with space around them. Explore the full 1:18 scale model cars range.

1:24 scale: the middle ground

1:24 sits between 1:18 and 1:43, at roughly 17–21 cm for a car. In the Vroomi catalogue it is used mainly for trucks and tractor units, where a larger scale would quickly become impractical.

For collectors: the Solido Scania S580 Highline shows how 1:24 gives a modern truck real presence without needing a full cabinet. See all 1:24 scale models.

1:32 scale: agricultural and slot-car territory

1:32 has long been a reference size in several hobbies, from slot cars to farm models. A car measures about 13–16 cm; tractors and trailers are the main subjects in our range.

For collectors: the Universal Hobbies New Holland T7.225 is a good example of how much mechanical detail the scale allows on working vehicles. Browse the 1:32 scale collection.

1:43 scale: the storyteller's scale

1:43 is the most widespread scale for model cars, especially in Europe. It comes from British O-scale model railways, where cars were first made as accessories for train layouts, and the first model car made exactly to 1:43 appears to be the French Dinky Toys No. 24R Peugeot 203 of 1951. From the 1950s to the 1980s it was the standard of Corgi, Dinky, Schuco, Solido, Polistil and many others, and later it became the main scale for hand-built resin and white-metal models.

At about 9–12 cm per car, 1:43 trades size for breadth: a 60 cm shelf holds eight to ten cars, enough for a full Le Mans podium, a WRC season or a brand's history decade by decade.

For collectors: 1:43 is the scale for grids and timelines. Start from the 1:43 scale model cars collection, or from the historic rally selection.

1:64 scale: the pocket grid

1:64 was born by halving 1:32, and in the United States it was also the S scale of model railways from the late 1940s to the mid-1960s. Matchbox and Hot Wheels describe their cars as 1:64, even though the real proportions of those toys vary widely. Premium 1:64 models are now made to precise scale, at about 6–8 cm per car.

For collectors: dozens of cars fit on one shelf, which makes 1:64 ideal for dioramas and for following a model line across many years. See the IXO Mack B61 and the full 1:64 scale collection.

Helmet scales: 1:2 and 1:5

Racing helmets use their own scales. A 1:2 mini helmet is half the size of the real one and reproduces the driver's design in great detail; a 1:5 helmet is a compact desk piece, often supplied with a display base.

For collectors: compare the Oscar Piastri 1:2 mini helmet with the Charles Leclerc 1:5 helmet by Looksmart. Browse the 1:2 and 1:5 helmet collections.

Which scale should you collect?

If you have little space

Choose 1:43, or 1:64 for very large themes. You can tell a complete story on one shelf.

If you want maximum detail

Choose 1:18 for most subjects and 1:12 for the few cars that matter most to you. Add a 1:8 only if you have a dedicated spot for it.

If you collect a race, a season or a brand

Choose 1:43 for the whole field and add the winner in 1:18 or 1:12. Many collectors build exactly this way: breadth in 1:43, hero pieces in a larger scale.

If you collect trucks or working vehicles

1:24 and 1:32 give these large vehicles presence without overwhelming the room; 1:43 and 1:64 work well for complete fleets.
