Managing Your Guest List
Guest management can be surprisingly complex, especially for larger events. You need to account for people who will not attend, plus-ones, children, and dietary requirements. Our calculators help you plan realistic numbers.
RSVP acceptance rates vary by event type. For weddings, expect around 80-85% of invited guests to accept. For casual parties, acceptance rates are typically 60-75%. For children's parties, expect roughly 70-80% attendance. Always invite slightly more people than your target headcount.
Seating plans are crucial for sit-down events. Round tables of 8-10 are the UK standard for weddings and formal dinners. Our seating calculators help you work out table numbers and distributions so no table feels overcrowded or empty.
