How Is the Biggest Festival Measured
Size is usually measured by total attendance, number of stages, and duration. Single-day festivals may have high headcounts, while multi-day festivals are counted by cumulative visitors. Organizers report ticket sales and on-site counts, and independent sources such as event industry reports help verify claims about the largest gatherings.
