3. Get your schedule
A grid of shifts with how many people each one needs.
Common questions
A common rule of thumb: 1 volunteer per 10–15 expected attendees for most events. For check-in or food service, plan closer to 1 per 8.
Two to three hours is the sweet spot — long enough to be worth showing up for, short enough that people will commit.
