Final answer:
The size requirement per person for locker rooms is approximately 20 square feet as a common standard, but this can vary based on local building codes and specific facility needs.
Step-by-step explanation:
The size requirement in square feet per person for locker rooms depends on various factors such as the guidelines set by the organization, the intended use, and comfort standards. However, a common standard from the National Intramural-Recreational Sports Association (NIRSA) suggests roughly 20 square feet per person for a basic locker room. Local building codes and specific facility needs can impact this standard, so it is essential to consult these sources for more accurate requirements.
