When planning for fluctuations in attendance, what percentage buffer zone is commonly recommended?

When planning for fluctuations in attendance at events, a buffer zone of 10% is commonly recommended because it strikes a balance between accommodating potential increases in attendance while also not overcommitting resources. This percentage allows event planners to prepare for a reasonable uptick in attendance due to factors such as increased interest, last-minute registrations, or unexpected guests.

Using a 10% buffer helps ensure that there are enough resources, such as seating, food, and materials, without excessively inflating costs or logistics in anticipation of a larger-than-expected crowd. It reflects a practical approach to event management, acknowledging that while attendance can vary, it tends to do so within a manageable range. This guideline is widely adopted in the industry, making it a standard practice for effective event planning.
