Diecast Scale Guide: What Size Is Each Scale?
Diecast scale tells you how many times smaller a model is than the real vehicle. A 1:18 model is one eighteenth of full size — so the bigger the second number, the smaller the model. A 1:18 Corvette is over 10 inches long and commands a shelf; a 1:64 version of the same car fits in your palm. Neither is “better” — they serve different kinds of collecting. Here is what each scale in our catalog means in practice, and how to choose.
Scale size chart
| Scale | Typical car model length* | Best for |
|---|---|---|
| 1:12 | ~15 in / 37 cm | Large centerpiece display models with maximum detail |
| 1:18 | ~10 in / 25 cm | The classic showcase size — opening doors, detailed interiors |
| 1:24 | ~7.5 in / 19 cm | Display presence without the shelf space of 1:18 |
| 1:32 | ~5.5 in / 14 cm | Compact display models |
| 1:43 | ~4 in / 10.5 cm | The classic European collector standard — racing liveries, big themed collections |
| 1:64 | ~2.75 in / 7 cm | The collector staple (“matchbox size”) — affordable, easy to collect in volume |
| 1:87 | ~2 in / 5 cm | HO scale — matches HO model railway layouts |

1:18 — the showcase scale
This is the scale most people picture when they think “collector’s model”: opening doors, detailed engine bays, steerable wheels, real fabric seatbelts on premium releases. Brands like AUTOart, GT Spirit and Solido do their best work here, and typical prices run $40–$400+. The trade-off is space — a dozen 1:18 cars fill an entire bookshelf. If you want five models you’ll display proudly rather than fifty in a drawer, start with 1:18.
1:24 to 1:27 — the sweet spot
Roughly hand-sized, still detailed enough for opening parts on many releases, and significantly cheaper than 1:18 at $15–$80. Jada, Motormax and Maisto dominate this range, and American muscle is especially well covered. It’s the scale we recommend to most new collectors — big enough to appreciate, small enough to grow a real collection. Browse 1:24–1:27 models.
1:64 — small size, serious collecting
Don’t dismiss this as toy territory. Premium 1:64 from Mini GT, Tarmac Works and INNO64 features metal bodies, rubber tires and factory-accurate liveries — and lets you own fifty JDM legends in the space one 1:18 car occupies, usually for $5–$60 apiece. This scale also has the strongest limited-edition chase culture. See 1:64 models.
1:43 and 1:87 — specialist favorites
1:43 is the classic European racing scale — most Le Mans and F1 subjects appear here first, typically at $15–$120. 1:87 (HO) matches model railroad layouts at $10–$40, which is why Oxford Diecast’s classic American cars in this scale are beloved by layout builders.
Aircraft scales
Aircraft models use their own conventions: 1:72 is the classic military-aviation scale (a fighter jet comes out around 8–10 in), while airliners are usually 1:200 (~14 in for a typical narrow-body) or 1:400 (~7 in) — compact enough to build a whole fleet.
Which scale should you collect?
There is no wrong answer — most collectors settle on one or two scales so their shelf looks consistent, because mixed-scale shelves never quite look right. Pick one “hero” scale for your main collection: if you want maximum detail for the money, go 1:18; if you want variety and volume, go 1:64; 1:24 is the balanced middle path. If you run a model railway, 1:87 vehicles will match your layout perfectly.
