The collector's guide
Diecast & Scale Guide
Small models. A world of possibilities. Understand the scales, spot the details that matter and find a model you will enjoy owning.
01 / The basics
What is a diecast model?
Die casting shapes molten metal inside a reusable mould. In model cars, metal parts give the miniature its familiar weight, while plastic, clear glazing and rubber may be used for other components. Construction varies by release: “diecast” does not mean every part is metal.
A good place to start is a car you like: a childhood favourite, a dream road car, a racing memory or a whole garage built around one theme.
02 / Size matters
What does 1:64 mean?
The ratio describes the model's size compared with the real vehicle. At 1:64, each measurement is one sixty-fourth of full size. A smaller number after the colon means a larger model of the same car.
A worked example using a 4.5-metre car. Lengths are calculated; the drawings show relative proportions, not actual screen size.
| Scale | Relative model size | Length |
|---|---|---|
| 1:18 |  | 250.0 mm |
| 1:24 | | 187.5 mm |
| 1:43 | | 104.7 mm |
| 1:64 | | 70.3 mm |
| 1:87 | | 51.7 mm |
Formula: real-car length in millimetres ÷ scale number = model length in millimetres. A longer real car makes a longer miniature at the same scale.
Try your own car length
Use the real vehicle's length, not the size of its packaging. This is a scale estimate, not a product measurement.
Why collect 1:64?
It gives you room to build a varied collection in a modest display space. You can compare road cars, race liveries and different makers without needing a large cabinet. Detail still varies between brands and individual releases.
Check the stated scale. Similar packaging sizes do not guarantee the same ratio. For example, a listing marked 1:62 is not exactly 1:64. Confirm dimensions when matching cars to a diorama, transporter or display case.
03 / Buy with confidence
Look beyond the scale
Decide how you will display it
Carded, boxed and loose describe presentation, not scale. Check model, card, blister and box condition in the individual listing. If you keep packaging, allow room for that too.
Compare the details you value
Look at wheels, tyres, paint, printed decoration and any opening parts. MINI GT describes metal construction and soft rubber tyres in its model details; features still need checking on each release. A larger scale or a “premium” label is not a promise of opening doors.
Choose for the person collecting
Follow a marque, a generation, a racing series or simply the cars you love. For gifts, check the manufacturer's age guidance: a delicate display model and a toy intended for play can have different requirements.
04 / Build your garage
Follow your collecting interest
Start with a theme, then compare the models and brands within it. Every listing keeps its own price, scale and availability.
