Abstract:
An improved court perimeter boundary for volleyball or other sports comprises at least one indicator that indicates a hypotenuse distance to be used in squaring the court delimited by the boundary. Optionally, the perimeter boundary may be separated, facilitating the setup of the court and the winding of the boundary for storage. A method of setting up a volleyball court is also described.
