18mm miniatures, also known as 1:100 or 1:120 scale miniatures, are small models commonly used in tabletop wargaming, historical reenactments, dioramas, and miniature collecting. They provide a slightly larger size compared to 15mm miniatures, allowing for more intricate details and easier painting.

These miniatures are often used to represent military units, vehicles, and structures in various historical periods, such as World War II, Napoleonic wars, or ancient battles. They are also popular for their compatibility with different wargaming systems, making them a versatile choice for gamers.

Working with 18mm miniatures allows hobbyists to enjoy a good level of detail without sacrificing too much space on the tabletop or in diorama setups. Painting and assembly techniques can be more forgiving compared to smaller scales, making them suitable for both beginners and experienced hobbyists.
