What is required for the center line of the court?

The requirement for the center line of a volleyball court is that it must be a continuous line, which may be shadow-bordered. The center line serves as a crucial boundary that separates the two sides of the court and indicates where the front row players must align during the serve and play. A continuous line ensures clear visibility and minimizes confusion. The shadow border allows for a visual distinction without compromising the integrity of the line itself, making it easier for players and officials to recognize. This specific marking helps maintain the rules and flow of the game effectively.

Other markings such as solid colors or dashes are not standard for the center line, as they do not fulfill the requirements that ensure the functionality and clarity needed in official play.
