Party planning checklist: timeline, quantities, and supplies
A useful party plan starts with the date, guest count, venue, and budget. For a typical three-hour celebration, confirm those basics 6-8 weeks ahead, send invitations 3-4 weeks ahead, order decor and tableware for your confirmed headcount plus 10% spare, and finalize food, drinks, setup, and cleanup during the last week.

Frequently asked questions
How far in advance should I plan a party?
Start 6-8 weeks ahead for a 20-50 person party. Confirm the date, venue, guest list, and budget first; send invitations 3-4 weeks ahead; then finalize quantities after the RSVP deadline.
How do I calculate party supplies?
Use the confirmed guest count, then add about 10% for disposable place settings and other consumables. Calculate seating from the event format: provide one seat per guest for a meal, or fewer seats only when the event is intentionally designed for mingling.
What should a party budget include?
Track venue, food and drinks, rentals, decor, entertainment, invitations, favors, delivery, tax, tips, and a contingency. Keep estimates separate from confirmed purchases so the total does not look more certain than it is.
