What is the triangular or center piece of a corner desk called, and how big is it?

The center connecting piece on a corner desk is called the corner unit or corner bridge. It typically measures 24” × 24” or 30” × 30” and fills the corner gap between the two wings, creating a continuous work surface across the full desk. In modular systems, the corner unit is an independent piece that connects to two separate wing sections. On many fixed desks, the corner unit is integrated into the overall structure. The size of the corner unit affects how much transition space you have between wings — a 30” corner unit feels more spacious than a 24” one.
