What percentage of invited guests actually attend?

For casual parties, expect 70-80% attendance. Formal events see 75-85%. Weddings typically get 80-90%. Kids parties have the highest rate at 85-95%. Corporate events are lower at 60-70%. These rates vary by time of year, day of week, and how far in advance you invite.

How does distance affect attendance?

Local guests (within 30 minutes drive) attend at 10-15% higher rates than distant guests. For weddings with many out-of-town guests, expect 15-20% lower attendance from those travelling. Providing accommodation information helps increase distant guest attendance.

When should I send invitations?

Send formal event invitations 6-8 weeks in advance. Wedding invites go out 8-12 weeks ahead. Casual party invites need 2-4 weeks notice. Save-the-dates for weddings should go out 6-9 months in advance. Giving more notice increases attendance rates.

Should I over-invite to hit my target number?

Yes, if you need exactly 50 guests, invite 60-65 for a casual party or 55-60 for a wedding. This accounts for typical decline rates. Some people also send a B-list of invites once early declines come in, though this is controversial for weddings.
