What are the standard dimensions of a diving board?

The standard dimensions of a diving board are generally around 16 feet in length and 20 inches in width, which aligns perfectly with the provided choice. These dimensions are designed to ensure that the board has the appropriate length for the spring and bounce required for safe diving, while also providing sufficient width for stability and safety for divers.

Additionally, these measurements typically conform to industry standards that prioritize safety and usability in recreational diving contexts. Boards that are too short or narrow may not provide the right trajectory or support necessary for divers, potentially leading to accidents or injuries.

The other dimensions presented in the other options either exceed or fall short of what is considered standard, making them less suitable for common diving practices. By adhering to a recognized standard, swimmers and divers can have a more consistent and safe experience when using these facilities.
