Scale tells you how many times smaller a model is than the real car: a 1:18 model is 18 times smaller, a 1:43 model 43 times smaller. For most collectors 1:43 is the most practical choice (compact, huge range), 1:18 suits a single detailed showpiece, 1:24 is typical for film and road cars, and 1:64 works for collections in a small space.
Below you will find a table of approximate lengths, how the level of detail differs, and advice on which scale to choose based on space, budget and what you want to collect.
How to read a model's scale
1:X means that 1 cm on the model equals X cm on the real car. Working out a model's length is simple: real car length ÷ X. A 4.5 m car will be 25 cm long at 1:18 and about 10.5 cm at 1:43.
The rule of thumb: the smaller the number, the bigger the model. So 1:12 is much larger than 1:64.
Table: approximate model lengths by scale
Values are calculated from the real car's length and rounded. Actual models can differ by a few millimetres depending on the manufacturer and whether you include the front and rear wings.
| Scale | 4 m car | 5 m car | F1 wheelbase 3.6 m (2022–2025) | Typical use |
|---|---|---|---|---|
| 1:12 | 33 cm | 42 cm | 30 cm | premium F1 models, motorcycles |
| 1:18 | 22 cm | 28 cm | 20 cm | detailed desk or cabinet models |
| 1:24 | 17 cm | 21 cm | 15 cm | film and road cars, kits |
| 1:32 | 12.5 cm | 15.5 cm | 11 cm | toy models, slot cars |
| 1:43 | 9.3 cm | 11.6 cm | 8.4 cm | F1, rally and Le Mans collections |
| 1:64 | 6.3 cm | 7.8 cm | 5.6 cm | small collections, palm-sized cars |
| 1:87 | 4.6 cm | 5.7 cm | 4.1 cm | model railways (H0) |
For F1 we use the wheelbase rather than overall length, because the F1 rules do not directly cap overall length, but they do limit the wheelbase. For 2026 the maximum wheelbase was cut from 3,600 to 3,400 mm and the width from 2,000 to 1,900 mm (source: Formula1.com). Models of 2026 cars will therefore be slightly shorter than 2022–2025 cars in the same scale.
1:18 – a large model with the most detail
A 1:18 model is big enough for the details to stand out: sponsor graphics, a cockpit with steering wheel, tyre markings and fine aerodynamic parts. Road car models in this scale often have opening doors or bonnets; single-seaters may have removable parts or steerable front wheels (depending on the manufacturer).
- Pros: the best balance of size and detail, a statement piece for a shelf or as a gift.
- Cons: takes up space (around 30 cm for an F1 car including wings), higher price, only a few fit on a typical bookshelf.
- For whom: fans of one driver or one winning car who want “the one” model.

1:24 – the sweet spot for road and film cars
1:24 is less common among F1 collectors, but very popular for road cars, American classics and film cars. The model is large enough for an interior and opening parts, yet takes up less room than 1:18.
A typical example are cars from the Fast & Furious film series in the Fast & Furious car models collection, or road car models in car models.
1:43 – the collector standard for F1, rally and Le Mans
1:43 is the most widespread collector scale for racing cars. An F1 model is roughly 11–13 cm long, so a whole season, a whole team or a driver's complete career fits on one shelf.
- Pros: the widest choice of cars and individual races (special liveries, winning cars), compact size, more affordable.
- Cons: fine details are simplified, cheaper ranges may not include a driver figure.
- For whom: anyone who wants to collect systematically – season by season, team by team.
1:43 also offers the most rally car models, including Czech crews; see rally car models or Bburago 1:43 models.
1:64 – small models for big collections
A 1:64 model fits in your palm: a 4 m car is only around 6 cm long, an F1 car roughly 8–9 cm. It is the classic toy-car scale, but in recent years it has also gained collector ranges with more faithful liveries.
- Pros: minimal space, low price, ideal for a desk or for children.
- Cons: limited detail, simplified printing.
Larger scales: 1:12, 1:8 and helmet models
1:12 appears with premium F1 models and motorcycles. LEGO Technic F1 cars are 1:8 – the 42141 McLaren Formula 1 set, for example, is about 65 cm long. Driver helmets usually come in 1:5, 1:4 and 1:2; a 1:2 helmet is half the size of the real one. You will find them in the helmet models collection.
Which scale to choose: a quick guide
| Situation | Recommended scale |
|---|---|
| I want to start collecting F1 and space is limited | 1:43 |
| I want one standout model of my favourite driver | 1:18 |
| I collect film and road cars | 1:24 |
| A gift for a child or a small desk piece | 1:64 |
| I collect whole rally seasons | 1:43 |
| I want to build the model myself | LEGO (Speed Champions, Technic 1:8) |
Stick to one scale
The most common mistake new collectors make is mixing scales. Cars of different sizes side by side look inconsistent and are harder to display. If you collect one series, stay with one scale and keep other scales on a separate shelf.
Check the scale in the description
Always check the scale in the product description. Some remote-control models and toy ranges use less usual scales (e.g. 1:16, 1:41 or 1:50) that do not fit a 1:43 or 1:18 collection.
Frequently asked questions
How long is a 1:43 scale F1 model?
Usually around 11–13 cm. The exact length depends on the car and season, because the F1 rules do not directly cap a car's overall length. The wheelbase is a useful guide: 3.6 m on 2022–2025 cars, which is about 8.4 cm at 1:43.
Is 1:18 bigger than 1:43?
Yes. The smaller the number after the colon, the bigger the model. A 1:18 model is roughly 2.4 times longer than a 1:43 model of the same car.
Which scale is best for starting a collection?
For most collectors, 1:43. The models take up little space, the choice of F1, rally and Le Mans cars is widest in this scale, and dozens fit in a single display cabinet. If you want one eye-catching piece for a desk, choose 1:18.
Are LEGO Speed Champions sets in a particular scale?
Not in a fixed scale like collectible models. Speed Champions F1 cars are around 19 cm long (the Audi R26 set, for example, is listed at about 19 cm), which puts them closer in size to 1:24–1:32. LEGO Technic F1 cars, on the other hand, are 1:8.
