1:18 vs 1:24 Scale Diecast Models: Which Size Is Right for Your Collection?
, by Linas Daukintis, 4 min reading time
Choosing between 1:18 and 1:24 scale diecast models is one of the most common decisions facing collectors. Both scales are incredibly popular, but they offer very different experiences in terms of detail, display space, and price. In this comprehensive guide, we compare these two beloved scales to help you decide which one best fits your collecting goals.
Understanding Scale Ratios: What Do 1:18 and 1:24 Mean?
A diecast model scale represents the ratio between the model and the real car. A 1:18 scale model means the car is 18 times smaller than the original — typically measuring 25–30 cm (10–12 inches) long. A 1:24 scale model is 24 times smaller, usually around 18–20 cm (7–8 inches) long. While the numerical difference seems small, the physical size difference is quite noticeable when you place both scales side by side.
Detail and Realism: 1:18 Takes the Lead
One of the biggest advantages of 1:18 scale models is the level of detail they offer. The larger size allows manufacturers to include features that smaller scales simply cannot accommodate. Premium brands like AUTOart and GT Spirit produce 1:18 models with opening doors, hoods, and trunks, detailed engine bays, realistic interior stitching, and even functional steering wheels. Many 1:18 models feature rubber tires, photo-etched parts, and hand-assembled components that create museum-quality display pieces.
That said, 1:24 models have come a long way. Brands like Bburago and Welly offer impressive detail at this scale, including opening parts and well-finished interiors. For many collectors, the detail level of a quality 1:24 model is more than sufficient.
Display Space: 1:24 Is More Practical
Space is often the deciding factor for collectors. A single 1:18 scale model takes up roughly twice the shelf space of a 1:24 model. If you have a dedicated display cabinet or a large collection room, 1:18 models create a stunning visual impact. However, if you live in an apartment or have limited shelf space, 1:24 scale models allow you to build a much larger collection in the same area. You can fit approximately 2–3 models in 1:24 scale in the space that one 1:18 model occupies.
Price Comparison: What to Expect
Budget plays a major role in scale selection. Here is a general price overview:
1:18 Scale Price Range
Bburago 1:18 models start from around EUR 25–40 for basic models. Mid-range options from Norev and Solido typically cost EUR 40–80. Premium brands like AUTOart and GT Spirit range from EUR 100–300+ for highly detailed resin or diecast pieces.
1:24 Scale Price Range
Welly and Maisto offer excellent 1:24 models starting from just EUR 10–20. Mid-range 1:24 options from Bburago cost EUR 20–40, making them ideal for beginners and gift-givers. This lower price point means you can build a diverse collection without a significant financial commitment.
Popular Brands by Scale
Different manufacturers tend to specialize in different scales. For 1:18 scale, the top choices include AUTOart (premium diecast and composite), GT Spirit (sealed resin models), Norev (excellent value sealed diecast), and Bburago (affordable opening models). For 1:24 scale, popular brands include Bburago, Welly, Maisto, and Motormax — all of which offer great variety at accessible prices.
Best Cars in Each Scale
Certain cars look particularly impressive in each scale. Supercars and sports cars like Ferrari, Lamborghini, and Porsche models shine in 1:18 scale where every aerodynamic detail is visible. Classic cars and muscle cars also look spectacular at this size. Meanwhile, 1:24 is perfect for building themed collections — imagine an entire shelf of BMW or Mercedes-Benz models spanning decades of automotive history. The smaller scale also works wonderfully for Volkswagen classics and everyday cars.
Collecting Strategy: Why Not Both?
Many experienced collectors maintain both scales in their collection. A popular approach is to keep 1:18 models for your absolute favorite cars — the dream machines you want to admire in the finest detail — while using 1:24 scale to build breadth across different makes, eras, and styles. This mixed approach gives you the best of both worlds: stunning centerpiece models alongside a diverse and growing collection.
