Die-Cast Scales Explained: 1:64, 1:43, 1:24 and 1:18
What die-cast scales mean in real centimetres: how big a 1:64, 1:43, 1:32, 1:24 or 1:18 model car is, why Hot Wheels are only roughly 1:64, and how to choose a scale to collect.
What the numbers mean
Die-cast scale is a ratio between the model and the real car. At 1:64, every centimetre of the model stands for 64 centimetres of the real thing. The bigger the second number, the smaller the model.
How big each scale really is
Here is how long a model of a typical 4.5-metre family car or sports car comes out at each common scale:
| Scale | Length of a 4.5 m car | Typical for |
|---|---|---|
| 1:64 | About 7 cm | Hot Wheels, Matchbox, Mini GT, Tarmac Works, Inno64, Tomica |
| 1:43 | About 10.5 cm | Detailed display models; a long-standing collector scale in Europe |
| 1:32 | About 14 cm | Some die-cast lines and slot cars |
| 1:24 | About 19 cm | Larger kits and die-cast, often with opening parts |
| 1:18 | About 25 cm | Large display models, usually with opening doors, bonnet and boot |
Why your Hot Wheels are not all the same scale
Mainline Hot Wheels and Matchbox cars are built to fit a standard blister card, so the box decides the size as much as the scale does. A small hatchback may be made a little larger than true 1:64 and a long truck or bus much smaller. That is why "1:64" on a mainline car really means "roughly 1:64".
Premium 1:64 brands such as Mini GT, Tarmac Works and Inno64 stay much closer to true scale, so their cars line up properly next to each other. If you mix mainline and premium cars on one shelf, expect some size differences. Our comparison of Mini GT and Tarmac Works goes into those two brands.
Choosing a scale to collect
- Space. A shelf a metre long holds a dozen or more 1:64 cars side by side, but only four 1:18 models.
- Budget. 1:64 is the cheapest way to build a large collection; 1:18 models cost many times more each.
- Detail. Larger scales usually have opening doors, bonnets and full engines; 1:64 detail lives in the paint, wheels and printing.
- The hunt. If you enjoy searching shop pegs, 1:64 is where Treasure Hunts and new releases appear every month.
Plenty of collectors mix scales: a deep 1:64 collection with a few 1:18 hero cars on top. Vanto records the scale of every car, so a mixed collection stays easy to sort and filter, and the Scale Shifter medal marks the moment you own three.
