bouwplaat

A bouwplaat is a flat, rigid plate used as a base for constructing models or scenes. In practice the term is most closely associated with base plates used in LEGO and other construction toy systems. The plate provides a stable, level surface with a grid or studs that allow bricks and elements to attach securely, helping builders keep their designs aligned and sturdy.

Common sizes and materials vary. The best-known example is the 32 by 32 stud base plate, widely used in LEGO sets, which translates to roughly 25.6 by 25.6 centimeters. Baseplates are typically made from ABS plastic and are available in many colors, including solid hues and transparent variants. Some specialty plates use reinforced plastics or smooth, non-stud surfaces for particular applications.

Uses and applications are broad. Baseplates serve as building surfaces for play, display, diorama construction, and model railways. They are also popular in stop-motion animation to provide a stable platform for scenes. Compatibility across brands varies; many baseplates are designed to accommodate bricks from multiple manufacturers that use the same stud-based connection system, though tolerances can differ.

Etymology and regional usage reflect its Dutch origin, with bouwplaat used in the Netherlands and Flanders to refer to any such building plate. While most often linked to LEGO, the concept extends to a range of baseplates and compatible surfaces used in model-making and educational contexts.
