Class 4 article

A Baseplate is a large flat plate in many colors, on which structures are often built ontop of. They can be bought as sets like 628 X-Large Grey Baseplate or come in sets that contain buildings. Compared to regular plate elements, baseplates are thinner and flat and their undersides cannot be connected to other studded pieces.


Baseplates are usually sized in multiples of eighth studs, although there are occassional exceptions such as 10x16, 14x14 or 50x50.

Most baseplates are completely covered with studs, while others have large entirely flat sections on their surfaces that are printed with various different patterns to act as roads, waterways etc.

Raised baseplates

A common variant of the baseplate is the so called "raised baseplate". These elements are large plastic pieces that are stretched out in the third dimension to form various landscapes. Raised baseplates usually represent hills and feature recesses that can serve as basements or caves for the structure built on top of them. Studs can be found on sections on the ground level as well as on the top or intermediate levels of the landscape.
