What is a ground plan in stagecraft?

A ground plan in stagecraft refers to a detailed diagram that represents the layout of a set or stage from a bird's-eye view, providing a to-scale depiction of the stage's physical elements. This visual aid is crucial for directors, designers, and technicians as it illustrates where each set piece, prop, and actor should be positioned during a performance. It helps establish the spatial relationships on stage and assists in planning the movement of actors as well as technical elements like lighting and sound.

The ground plan is an essential tool for communicating the design vision to the entire production team, ensuring everyone has a clear understanding of the staging requirements. It serves as a reference during rehearsals and performances, facilitating effective collaboration across different departments involved in the production process.
